Heterosis and Combining Ability Studies in Sorghum (Sorghum bicolor (L.) Moench) Over the Environments
In the field of plant breeding, the most important breakthrough has been considered as ‘heterosis’. Exploitation of heterosis on commercial scale and the systematic varietal improvement through hybridization are the main tools to increase the sorghum production. The success in the development of superior hybrids and/or varieties depends on the choice of parents for hybridization and amount and ...
متن کاملcombining ability and heterosis for seed yield and its components in indian mustard (brassica juncea l.)
brassica juncea l. is an important oilseed crop which occupies premier position in indian agriculture. developing high yielding genotypes has been a major breeding objective in indian mustard. present study was conducted at directorate of rapeseed-mustard research, india, during 2010-2013 to determine general combining ability (gca) and specific combining ability (sca) of parental lines and bet...
متن کاملCombining ability analysis for seed yield and its components in Sunflower (Helianthus annuus L.)
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...
متن کاملStudy of Gene Effects for Stalk Sugar Yield and Its Component Traits in Sweet Sorghum [Sorghum bicolor (L.) Moench] Using Generation Mean Analysis
Generation mean analysis was carried out to estimate the nature andmagnitude of gene effects for sugar yield and its component traits in sweet sorghum[Sorghum bicolor (L.) Moench. Six basic generations, namely P1, P2, F1, F2,BC1P1, BC1P2 of four crosses involving seven diverse parents were evaluated inrainy 2009. The mean performance of the F1 in all the crosses indicated dominantgene effect fo...
متن کاملCombining ability analysis for within-boll yield components in upland cotton (Gossypium hirsutum L.).
Cotton is an important cash crop worldwide, accounting for a large percentage of world agricultural exports; however, yield per acre is still poor in many countries, including Pakistan. Diallel mating system was used to identify parents for improving within-boll yield and fiber quality parameters. Combining ability analysis was employed to obtain suitable parents for this purpose. The parental ...
