Combining ability in rice
WebJun 30, 2024 · Combining ability in rice was studied with a set of 4 lines and 10 testers and their 40 hybrids. The magnitudes of gea variances were higher than sea variances for all the characters which indicated that additive gene action was predominant in the expression of traits. The estimation of gea effects for parents revealed that females, … WebAug 26, 2024 · Abstract. This study was conducted to analyze the combining ability for yield and yield contributing traits of selected rice genotypes. Eighteen F2 populations developed by half-diallel mating design and seven parental lines were planted in randomized complete block design in three replications.
