    Opis:
    In rabi season 2012, six diversed maize inbred lines were crossed in all possible combinations without reciprocals by using a half diallel mating design to obtain 15 single cross. Inbred parents and their F1 single crosses with a check were evaluated in rabi season 2013 to evaluate the role of general and specific combin-ing ability and heterosis for some quantitative traits. Significant general combining ability variances was observed only for cob height and specific combining ability variances were observed for plant height, cob height, cob length, cob girth, number of kernels per cob, cob weight and hundred grain weight. The GCA/SCA ratio was less than unity for all studied traits except shelling percentage; this means that these traits are pre-dominantly controlled by non-additive gene action. Based on GCA estimates, it could be concluded that the best combiners were ML01, ML05 and ML29 inbred lines for most of the studied traits. This result indi-cated that these inbred lines could be considered as good combiners for improving these traits. Significant positive SCA effects were found for all studied traits except number of kernels per row and shelling percent-age. Based on SCA effects, it could be concluded that the crosses ML01×ML02, ML02×ML05, ML02×ML29 and ML05×ML15 could be exploited by the maize breeders to increase maize yield. Three F1 hybrids such as ML02×ML15, ML02×ML29 and ML05×ML15 proved to be the outstanding hybrids to immediate further steps for commercial cultivation. In a conclusive decision the F1 hybrid, ML02×ML29 was the best combina-tion as evaluated through combining ability and standard heterosis.

    Opis:
    An analysis of combining ability of rye, based on F1 generation hybrids, was performed in order to select lines of high effects of general combining ability which are useful for creation of population and synthetic varieties as well as hybrids giving high effects of specific combining ability. The main aim of the present paper was to recognize the actions of genes responsible for quantitative traits and combining ability of rye inbred lines on the basis of F1  and F2  hybrids analysis.The study material included 56 F1 generation hybrids obtained though diallel-cross with 8 parent lines as well as 56 F2  generation hybrids crossed with 8 parent lines.A genetic analysis of generation F2 yields results and GCA estimates which substantially correspond with those obtained for generation F1. The closest results were obtained for plant height, ear length and 1000-grain weight. For cultivation purposes, an analysis of generation F2  will be reliable and the selection based on it successful. Most of the studied lines were found to essentially influence the effects of general combining ability. The most recommendable is the line SMH-49 whose progeny was characterized both by shortened leaves and increased 1000-grain weight and the weight of grains per ear.

    Opis:
    Effects and variances of general (GCA) and specific (SCA) combining ability have been estimated from two experiments. For the first experiment (EXP 1) 19 homozygous lines originating from the Petkus pool were crossed with two CMS single cross testers derived from the Petkus pool (intra-pool test crosses) and with two testers from the Carsten-Danko pool (inter-pool test crosses), respectively. In the year 2000 grain yield was measured at 5 locations in Germany. The second experiment (EXP II) comprised a factorial of inter-pool crosses by using 4 homozygous CMS Petkus pool lines as seed parents and 6 Carsten-Danko lines as pollen parents. The respective 24 inter-pool crosses were evaluated for grain yield on several locations in 1996 and 1998.In EXP I GCA-variance of candidate lines (4.7 —5.9 q/ha2 was estimated to have a similar size as SCA-variance. Possible reasons for an overestimation of SCA-variance are extreme divergence between testers, insufficient removal of inbreeding effects in the intra-pool test crosses and bias due to SCA × year interaction-variance. The use of intra-pool testers should be restricted to breeding material where inbreeding due to consanguinity between testers and candidate lines is either absent or will evenly affect test cross performance of all candidates.In EXP II GCA-variances for female 9.2 q/ha2 and male 2.4 q/ha2 lines were much higher than SCA-variance. Repeatability for GCA-effects over different environments was medium (r=0.67), whereas for SCA-effects it was low (r=0.13). Selection intensity for yield should therefore be moderate, if based on a single year of testing only. Selection of parental components for hybrids and prediction of hybrid performance should mainly base on GCA-effects. Alternative to the use of factorial crosses test crosses with testers representing the opposite pool are recommended. Testing for SCA-effects and for SCA x environment interaction- effects can be a valuable diagnostic tool, to become aware of strengths and weaknesses of the elite material used to build new hybrids. SCA-tests should therefore be performed by using highly divergent environments.

    Opis:
    Combining ability analysis and heterosis for cotton fiber quality traits were studied in a set of diallel crosses involving eight cotton (Gossypium sp.) genotypes. Randomized complete block design was used to test 56 F1 and 8 parents for fiber quality traits; length (Len), strength (Str), micronaire (Mic), uniformity (Unf), elongation (Elg), spinning consistency index (Sci) and short fiber index (Sfi). Analysis revealed significant general combining ability (GCA) and specific combining ability (SCA) effects for all the traits and additive gene effects were important in the inheritance of the traits. Giza-45 had the highest GCA effects for Len, Sci, Unf and Elg while Is-4 had the highest Str value. Mic and Sfi values were lowest for Askabat-100 and Giza-45, respectively. The cross Cukurova-1518 × 108-F and Nazilli-84S × Askabat-100 had the lowest SCA effects for Mic and Sfi, respectively. The highest values for Len (Askabat-100 × 108-F), for Str (Acala Prema × 108-F), for Sci (Is-4 × Giza-45), for Unf (Stoneville-453 × Askabat-100) and for Elg (108-F × Is-4) were also obtained. Hybridizations among Askabat-100 × Nazilli-84S, Is-4 × Giza-45, Askabat-100 × Stoneville-453, Askabat-100 × Giza-45, Is-4 × 108F, Giza-45 × 108F, Giza-45 × Acala Prema, Nazilli-84S × Giza-45, Is-4 × Nazilli-84S and Acala Prema × Askabat-100 crosses yielded the best heterosis and heterobeltiosis values. Aforementioned parents and crosses could be utilized for further selection of high fiber quality and applying 3-way crosses or modified backcross or recurrent selection to genotypes having good combining ability would improve fiber quality...
