Opis:: The use of 2,4-D as a post pollination treatment to fertilize florets instead of GA₃ provided a two-fold improvement in seed set, culturable embryos and hence green plant production from wheat and maize pollination. The efficiency of the wheat by maize pollination method for haploid production was equal to the anther culture method in F₁ hybrid combinations that were responsive to anther culture. However, in recalcitrant combinations obtained from non-responsive genotypes the maize pollination method was far superior.

Opis:: Recent advances at Institute of Grassland and Environmental Research (Aberystwyth, U.K.) in cytogenetics of the Lolium/Festuca complex places us in the advantageous position of being able to map genes of agronomic importance onto chromosome arms using fluorescence in situ hybridization (FISH). The ability to physically map genes leads to the capability for "dissecting" quantitative traits into their different components and will lead to better understanding of the complex physiological processes involved and the identification of their genetic control. By tagging genes of interest, using molecular and morphological markers, it will be possible to select and combine suites of desirable genes in a single genotype and thus produce novel cultivars by conventional breeding procedures. Programmes for introgression depend on the relationships between species and on levels of chromosome pairing. Phylogenetic relationships within the Lolium/Festuca complex are being determined using both genomic in situ hybridization (GISH) and FISH. With recent advances in genetic manipulation within the Lolium/Festuca complex, opportunities now arise for gene transfer from Lolium and Festuca species into other important agricultural crops.

Opis:: Tolerance to a new herbicide, pyributycarb, was evaluated both at the plant and cellular levels. Several highly or moderately tolerant strains chosen at the plant level, showed a parallel relation of to tolerance at the cellular level. However, on the whole, correlation between total tolerance indices and survival rates of calli was not significant in 18 out of the 80 studied strains. As a result of somaclonal selection for two herbicides, lines NB-200 and NM-100 were regenerated from the tolerant calli screened with benthiocarb at 200 ppm, and molinate at 100 ppm, respectively. In the R₂ generation, both the lines displaned a stable tolerance both at the plant and cellular levels. Thus the highly tolerant mutant lines were developed from a moderately tolerant line, N-61, via in vitro selection. To achieve a short-cut method in the interspecific genetic exchange, a series of techniques related to cell fusion were established in rice and related species. Two kinds of somatic hybrids between the cultivar Kitaake and tetraploid Oryza species, O. punctata and O. officinalis, were successfully produced. Among the somatic hybrid plants, a wide range of chromosomal variation was observed. Aneuploid plants with a chromosome number around 2n = 72 (hexaploid), which are expected from a symmetric fusion between diploid and tetraploid strains, were obtained showing mixoploidy within a plant. Most of the somatic hybrids were characterized by intermediate features of plant-type showing high sterility, shattering of spikelets and reduced plant height. As an exception, a diploid plant, which was identified by RFLP analysis using the rDNA gene probe, closely resembled Kitaake and produced viable seeds. A tetraploid hybrid plant was also promising for the introduction of economically important characters through the reduction of chromosome numbers by doubled haploids. Gametoclonal variation and gamma radiation was applied to Kitaake. The mutation frequency was prominently increased by gamma ray treatment, especially at high doses of 200 Gy or 300 Gy. In the M₃R₂ or M₄R₃ generations, most of the variants showed unfavourable characters. Most of the mutant characters were governed by single or double recessive genes. Several mutants such as short culm and early flowering time might be used for rice breeding.

Opis:: Eight anther-derived DH lines of pepper hybrids: two red-fruited (AP14, AP15) and two yellow lines (AP25 and AP32) of C. annuum (ATZ1 × PO)F2, two lines of (C. frutescens × C. annuum)F1 (FA1, FA2), and two of (C. frutescens × C. chinense)F1 (FCH2, FCH3), were studied regarding important morphological plant and fruit characters. C. annuum breeding line ‘ATZ1’ was used as a standard. The following traits were evaluated: total fruit yield, fruit weight, weight of placenta with seeds, technological matter, pericarp thickness, extract content, dry matter content, weight and number of seeds per fruit. The level of homogeneity within the DH lines was analysed with a one-way analysis of variance, additionally the values of coefficient of variation (CV) were determined for the tested plant characters. The highest phenotypic uniformity was noted for the red-fruited lines obtained from anthers of (ATZ1 × PO)F2 and for the DH lines of (C. frutescens × C. annuum) F1, while the least uniform were FCH2 and FCH3 lines of (C. frutescens × C. chinense)F1. The DH lines AP14 and AP15, as well as FA1 and FA2 were phenotype homogeneous in respect of weight of fruit, technological matter, pericarp thickness and extract content. For these parameters, also the values of CV were the lowest. Statistically significant interline polymorphism between the androgenic lines of the same origin was detected among the lines of C. annuum (ATZ1 × PO)F2.
W pracy oceniono wybrane cechy plonotwórcze ośmiu linii DH, otrzymanych w kulturach pylników mieszańców papryki (Capsicum spp.): C. annuum (ATZ1 × PO) F2 (dwie linie czerwonoowocowe – AP14, AP15 i dwie żółtoowocowe – AP25 i AP32), (C. frutescens × C. annuum) F1 (FA1, FA2) oraz (C. frutescens × C. chinense) F1 (FCH2, FCH3). Linia hodowlana C. annuum ATZ1 została wykorzystana jako standard do porównań. Oceniano całkowity plon owoców z rośliny, masę owocu, masę łożyska z nasionami, masę technologiczną, grubość ścian perykarpu, zawartość ekstraktu i suchej masy oraz masę i liczbę nasion z owocu. Wyrównanie każdej z linii określono przy pomocy analizy wariancji oraz współczynnika zmienności cech (CV). Najwyższą jednorodność fenotypową roślin stwierdzono w przypadku czerwonoowocowych linii DH, otrzymanych w kulturach pylników mieszańców (ATZ1 × PO) F2 oraz (C. frutescens × C. annuum) F1. Linie AP14, AP15 oraz FA1 i FA2 były wyrównane między innymi pod względem masy całkowitej oraz technologicznej owocu, a także grubości ścian perykarpu i zawartości ekstraktu. Dla tych cech odnotowano również najniższe wartości CV. Najmniej wyrównane fenotypowo okazały się linie FCH2 i FCH3, pochodzące z kultur pylników międzygatunkowego mieszańca (C. frutescens × C. chinense) F1. Istotny statystycznie, międzyliniowy polimorfizm cechował cztery androgeniczne linie wewnątrzgatunkowego mieszańca C. annuum (ATZ1 × PO)F2.

Opis:: The aim of the research was to assess the androgenic potential of 21 Polish cultivars of spring and winter barley. On average, a few green plants developed per 100 anthers. Cold pretreatment proved conducive to the formation of embryos/calli, while mannitol pretreatment favoured green plant development. The first embryos/calli formed on the induction medium developed most efficiently. The authors chose FHG medium supplemented with 1 mg/l BAP and 0.2 mg/l 2,4-D (induction of androgenesis) and FHG medium supplemented with 0.4 mg/l BAP and 3% maltose (plant development).

Opis:: Using in vitro androgenesis serves as a unique opportunity to produce doubled haploid (DH) plants in many species. More benefits of this biological phenomenon have kept these methods in the focus of fundamental research and crop breeding for decades. In common wheat (Triticum aestivum L.), in vitro anther culture is one of the most frequently applied DH plant production methods. The efficiency of in vitro wheat anther culture is influenced by many factors, such as the genotype, growing conditions, collection time, pre-treatments, and compositions of media and culture conditions. According to some critical review, the genotype dependency, low efficiency and albinism are mentioned as limitations of application of the anther culture method. However, some research groups have made significant efforts to diminish the effects of these bottlenecks. Due to the improvements, a well-established in vitro anther culture method can be an efficient tool in modern wheat breeding programs.

Opis:: Anther and somatic tissue culture in combination with mutagenesis were carried out to evaluate the efficiency of different mutagenic treatments of various in vitro culture materials, and to obtain some promising variants for rice improvement. Results indicated that in japonica rice radiation treatment of dry seeds and young panicles influenced the percentage of green plantlets regeneration from anther culture. Both treatments increased significantly the percentage of regenerated green plantlets in comparison with the control. Irradiation with 30 Gy of rice callus increased also the percentage of regenerated green plantlets. For indica rice, the combination of the suitable dose of gamma rays irradiation on seeds and an improved medium, increased the percentage of callus induction. This approach made it possible to use anther culture in indica rice breeding. Somatic tissue cultures combined with radiation-induced mutagenesis led to the development of a number of promising mutants including some new cytoplasm-nucleus interacting male-sterile lines with almost 100% stigma exsertion. Their development would be of practical significance for increasing the genetic diversity for production of hybrid rice.

Opis:: F₁, F₂ populations as well as F₃ and F₄ wheat lines coming from more than 300 cross combinations have been used for androgenic wheat studies and more than 5000 haploid plants were produced. Promising doubled haploid lines were tested together with lines produced in the conventional way in yield trials. The two best doubled haploid lines overyielded the standard. On the basis of results related to the general combining ability it is advisible to cross parents with a good combining ability for characters such as high percentage of responding anthers and embryo/callus induction with parents indicating a good combining ability for green plant production. In this way ideal lines can be obtained for doubled haploid production.

Opis:: The effect of C17 and W14 induction media on the formation of embryo-like structures (ELS) from F3 generation of nine hexaploid oat hybrids was investigated in the study. In all genotypes, the highest number of ELS (0.6 - 12.1/100 anthers) was obtained on C17 medium. The efficiency of plant regeneration on medium 190-2 was tested, in relation to different ELS culture conditions. The highest rate of green plants per 100 ELS (3.3 - 42.4) was produced by incubation at 22oC in the dark for the first two weeks. Among 36 green regenerants, 28 (77.8%) were haploid and 8 (22.2%) were spontaneous doubled haploids, fully fertile. After colchicine treatment of haploid plants, 19 were partially fertile and set from 1 to 15 seed per panicle.

Opis:: W kulturach pylnikowych 15 form mieszańcowych pszenżyta ozimego badano częstotliwość uzyskiwania androgenicznych roślin. Ze wszystkich genotypów otrzymano zielone rośliny, przy czym częstotliwość wahała się od 0,4 do 15,2/100 pylników w poszczególnych genotypach. Dla regeneracji roślin zastosowano pożywkę 190-2 z dwoma stężeniami kinetyny (0,5 lub 1,5 mg/l). Na pożywce zawierającej 0,5 mg/l kinetyny otrzymano więcej zielonych roślin, tj. od 2,5 do 46,7/100 androgenicznych struktur. Poziom ploidalności oznaczono cytometrycznie u 350 roślin i w zależności od genotypu stwierdzono od 17,6 do 80,0% spontanicznie podwojonych haploidów. Ogółem uzyskano 80,3% linii DH pszenżyta ozimego, wśród których było 38,0% spontanicznie podwojonych haploidów, natomiast w wyniku kolchicynowania 209 roślin haploidalnych otrzymano 70,8% linii DH.
We investigated the rate of obtaining androgenic plants using anther culture of 15 winter triticale hybrids. Green plants were obtained from all genotypes, with the frequency ranging from 0.4 to 15.2/100 anthers. The medium 190-2, with two different concentrations of kinetin (0.5 and 1.5 mg/l), was used for plant regeneration. Higher number of green plants was observed in the case of the medium with 0.5 mg/l of kinetin (2.5–46.7/ 100 androgenic structures). Ploidy level was determined by flow cytometry in 350 plants and showed from 17.6 to 80.0% spontaneously doubled haploids, depending on the genotype. A total of 80.3% of DH lines was obtained, among which 38.0% were spontaneously doubled haploids, whereas 70.8% of DH lines was obtained from colchicine treatment of 209 haploid plants.

Opis:: With the numerous improvements in cereal tissue and wheat anther culture, it is necessary to determine which of the improvements should be combined for optimal response. This study was conducted using one highly responsive cultivar of wheat (Triticum aestivum L. cv. Pavon 76) to test the effectiveness of pre-culture cold treatment (0 or 3-7 days at 5°C) of anthers, five initiation basal media, and various changes in Murashige-Skoog regeneration media. A cold pre-culture treatment was inhibitory for all initiation media for embryoid initiation. Of the initiation media, P1, 85D12, and N6 were similar for embryoid initiation (0.80 to 0.90 embryoids/anther) without a cold pre-culture treatment. Plant regeneration was improved by the addition of amino acids or glucose, increased sucrose concentration, filter sterilizing the medium, and altering plant growth regulator concentrations. P1 medium which is normally used for embryoid initiation was also beneficial for improving plant regeneration. Ethylene inhibitors were generally not beneficial.
