Stability 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 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 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 کاملT Evaluation of genes effect and combining ability in selected maize (Zea mays L.) lines
Maize is one of the most important grain and forage plants that has a unique role in the food and feed, especially poultry feed. To study the genetic effects, genes act and identify the best hybrid combination for morphological traits, experiment was carried out in diallel cross layout using 19 parents at Gorgan Agricultural Research Station, Iran in 2013. The progenies were planted in three re...
متن کاملEvaluation of genes effect and combining ability in selected maize (Zea mays L.) lines
To evaluate radiation use efficiency and weed control, this experiment was conducted in two locations in Ahwaz, Iran, in a randomized complete block design with 14 treatments and four replications in 2016-2017. Treatments included: Sole sugarcane, Sole soybean, Sole cowpea, Sole soybean+rhizobium, Sole cowpea+rhizobium, Sole sugarcane+mycorrhizal, Intercropping sugarcane with cowpea, Intercropp...
