Combining Ability Effects for Mineral Elements in Forage Sorghum Hybrids
The concentrations of minerals in forages are important in satisfying animal requirements, but little attention has been given to determining these concentrations in forage sorghum (Sorghum bicolor (L.) Moench.) breeding programs. In this 2-yr study, the objectives were to determine the contents, genetic variability, combining ability effects, and correlations for 12 mineral elements in 49 expe...
متن کاملStability of Combining Ability Effects in Maize Hybrids
General and specific combining ability effects are important indicators in a maize (Zea mays L.) breeding program aiming hybrid development. The objectives of the present study were to estimate the general (GCA) and specific combining abilities (SCA) effects of commercial maize hybrids using a complete diallel scheme and to assess the stabilities of these estimates. Fifty-five entries were asse...
متن کاملCombining ability and heterosis for diastatic activity in grain sorghum
Eighty-five sorghum (Sorghum bicolor (L.) Moench) entries including 13 restorer-lines (lines), 5 maintainer-lines (testers), 65 F1 hybrids, and two controls, were grown at Muzarabani, Zimbabwe during the rainy seasons of 1986/87 and 1987/88 to study the combining ability and heterosis for diastatic activity. Grain samples were evaluated for diastatic activity, expressed in Sorghum Diastatic Uni...
متن کاملEstimation of Combining Ability and Gene Effects in Forage Maize (Zea mays L.) Using Line × Tester Crosses
Abstract Determination of gene effects and combining abilities is a critical stage in maize hybrid breeding. In the present study, 20 S6 lines as female and three S6 inbred lines (K18, K19 and K1264/5-1) as tester were crossed and the resulting test cross progenies were evaluated in a randomized complete block design with three replications in 2008. During the growing period, several agronomi...
متن کاملHeterosis 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 ...
