Estimation 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...
متن کاملCombining Ability Study of Biochemical and Physiological Traits of Maize (Zea mays L.) Using fourth Dialllel Griffing’s Method
Biochemical and physiological traits are affected by environmental stresses and therefore the breeding of these traits will play an effective role in stress tolerance. In this study, hybrids of five S7 lines of maize in a 5 × 5 half-diallel design were investigated in order to study the combining ability of biochemical and physiological traits of maize at the Research Farm of Graduate Universit...
متن کاملStudy on Combining Ability and Gene Effects Estimation in Some Sweet Corn Inbred Lines (Zea mays L. var saccarata) by Line × Tester Method
In breeding programs determination of gene effects and general and specific combining ability for screening of test crosses is necessary. In order to estimate the genetic variance components and the general and specific combining ability of sweet corn lines, an experiment was conducted using 8 sweet corn S6 inbred lines (including 4 maternal and 4 paternal lines) by line × tester mating design ...
