Abstract: Forty-nine genotypes of bread wheat (Triticum aestivum L.) were screened at District farm, AB Block, B.C.K.V. situated at Kalyani in Nadia district of West Bengal during Rabi season for two years, i.e. 2015-2016 and 2018-2019 following Randomized Block Design. All the genotypes exhibited a considerable amount of variability for the parameters studied. PBW 744, UP 2940, DBW 187, HD 3219, K 1502 and WH 1201 were high yielding ones. A closer PCV & GCV was reported for all the characters except grain weight spike-1. High PCV, GCV, heritability, GA, GA % of mean was reported for the characters viz., days to heading, days to flowering, no of tillers plant-1, grain protein content and yield plant-1. The yield had a significant positive association with the number of tillers plant-1, number of grains spike-1 and test weight. The selection of genotypes may be done with the help of identified traits like the number of tillers plant-1 and test weight.
