Eight bread wheat genotypesof diverse origin were crossed in a half-diallel model in 2011/2012 season. The eight parents (Sahel-1 P1, Giza-168 P2, Misr-1 P3, Gemmieza-9 P4, Gemmieza-11 P5, Line-1 P6, Line-2 P7, Line-3 P8) and their 28 F1 hybrids were evaluated under normal and water stress conditions during 2012/2013 season in a two field experiments wereas designed a randomized complete block ...

Cotton is very important crop regarding the global trade. It grown for its fiber and edible oil in Pakistan. contributes 1.5 percent to GDP 69 foreign exchange. There need enhance yield per unit area of cotton by developing high yielding stress tolerant varieties. In breeding program parents their crosses are selected on basis combining ability. Combining ability analysis performed identify gen...

In the present study, a set of six female (lines) and seven restorers (testers) pearl millet were crossed in Line × Tester mating fashion. The newly synthesized hybrids evaluated for yield performance during Summer, 2020. high magnitude SCA variance indicates predominance non-additive gene action all characters. Hence, heterosis breeding method is suggested to exploit this kind action. estimate...

Twenty four lines were crossed with two testers in an L x T mating design to estimate the combining ability for seed yield in sunflower. Non-additive genetic variance played a preponderant role in the inheritance of all the characters studied viz., days to 50 % flowering, days to maturity, plant height, head diameter, volume weight, hundred seed weight and seed yield per plant. The lines 27, 43...

A study was carried out to assess the combining ability of ten CMS lines with four testers using line x tester method. Biometrical observations were taken for days 50% flowering, plant height, head diameter, maturity, volume weight, hundred seed yield /plant, oil content and yield/plant.  Specific combing variance greater than general all characters which indicated that non-additive gene a...

Estimation of general and specific combining ability effects in a diallel analysis of cross-pollinating populations, including the selfed parents, is presented in this work. The restrictions considered satisfy the parametric values of the GCA and SCA effects. The method is extended to self-pollinating populations (suitable for other species, without the selfed parents). The analysis of changes ...
