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:
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.

Anthers of twenty triticale genotypes were cultured on three different media: 1 - PII (Chuang et al. 1978) with increased 2,4-D to 2 mg L⁻¹ and agarose 6 g L⁻¹ , 2 - Macro-, micronutrients and vitamines like in MN6 (Chu, Hill 1988) + 2 mg L⁻¹ 2.4-D + 0.5 mg L⁻¹ KIN + 5 mg L⁻¹ FeEDTA + 90 g L⁻¹ sucrose; 3 - Macro-, micronutrients and vitamines like in MN6 (Chu, Hill, 1988) + 2 mg L⁻¹ 2.4-D + 0.5 mg L⁻¹ KIN + 5 mg L⁻¹ FeEDTA + 120 g L⁻¹ sucrose. Embryoid induction and plant regeneration were influenced by donor plant genotype and induction medium. Medium 1 was the best for embryoid induction, while for green plant regeneration the best were media 1 and 2. Out of 300 anthers from each genotype plated on each of the three media, 64-1250, 12-486 and 6-212 somatic embryos and 8-86, 3-136 and 1-26 green plants were recorded, on media 1, 2 and 3, respectively.

Opis:
A large population of anther culture-derived barley regenerants and their progeny was tested for allele segregation at 1 isozyme and 8 morphological marker loci. The segregation of genetic markers was examined separately for haploid, diploid and polyploid regenerants. All the 9 analysed genes except al (albino lemma) on chromosome 3 segregated according to the expected 1:1 ratio in the microspore-derived barley population. There was no difference in allele distribution between haploid and diploid regenerants. Among the limited number of 34 analysed tetraploids a significant excess of the dominant allele at locus о (orange lemma) of chromosome 6 was also observed. The recombination frequency between linked genes (n - lk2 on chromosome 1 and r - s on chromosome 7) estimated in the DH population did not differ significantly from recombination rates calculated in F₂ progeny or presented in barley chromosome maps. The phenomenon of gametic selection is discussed in relation to the genotype dependency of anther culture response and procedures used for DH production in barley.

Opis:
The influences of genetic and environmental factors on the anther culture responses of wheat were investigated. Significant differences for callus induction, plant regeneration, and green plant percentages were observed when the nucleus of Triticum acstivum L. cv. Selkirk was transferred to ten alien cytoplasms by substitution backcrosses. In most cases, the alien cytoplasms decreased anther culture responses, but sometimes they were as good as or better than the T. aestivum cytoplasm. Significant within-genotype variation for anther culture responses were observed for wheat varieties Chris, Yecora Rojo, WA7176 and Edwall, indicating genetic heterogeneity in the present commercial cultivars, and potential for improving anther culture responses by in vitro prescreening. When five genotypes (Chris, Pavon 76, Butte 86, WA6916, and Edwall) were cultured across three (potato-4 liquid, 100 g L⁻¹ ficoll-supplemented, and 6 g L⁻¹ agar-solidified) induction media, the liquid and ficoll-containing media were 10 to 15 times more productive than the agar-solidified medium. Whereas, the ficoll medium was not significantly different from the liquid medium. Several low concentration starch media appeared promising to replace current induction media. The starch media sustained the highcallus-induction properties of the liquid medium, while improving callus aeration similar to that observed on solid media, resulting in markedly higher plant regeneration and green plant percentages.

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:
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.
