Gene action for yield and its components in chickpea

Generation means analysis involving nine generations of each of the three crosses, effected from three genetically diverse parents, was used to elucidate the inheritance of grain yield and its components in chickpea. Both, additive and non-additive gene actions were involved in the inheritance of most of the characters. Duplicate type of gene action was involved in the expression of days for flowering, days for maturity, fruiting branches per plant and 100 seed weight. Grain yield was found to be predominantly under the control of dominance effect. These observations implies the use of biparental approach/intermeting of segregants in early segregating generations, for improvement in grain yield.
