Present investigation was carried out to study the variability parameters of quantitative as well as qualitative traits and their contribution towards seed yield which may be used as selection criteria for yield improvement in wheat under rainfed condition. Thirty six genotypes of wheat were studied for two consecutive years 2014-2015 and 2015-2016 following Randomized Block Design (RBD) with two replications in this experiment at Kalyani District of West Bengal. A wide range of variability was observed in all characters except chlorophyll- a, chlorophyll-b, total chlorophyll content that indicating sufficient scope for further selection in these traits under rainfed situation. High PCV, GCV, heritability, GA, GA % of mean was observed in the characters viz., Number of grains spike-1, Amylose content, Flag leaf area, Number of florets spike-1 and Test weight under rainfed condition in 36 genotypes of wheat. It implies that, these characters showed predominance of additive gene action. Therefore stabilizing selection should be followed for accumulation of alleles exhibiting additive gene action.
