关键词：Abstract : The objective of this breeding study was to develop and identify superior bivoltine breeds possessing the desired targeted traits on productivity along with higher survival under the varied and fluctuation climatic conditions of West Bengal. Initially bivoltine breeds collected from different parts of the country were screened under the ambient conditions of West Bengal. The breeds with high survival with moderate productivity traits were selected as potential parents for this study. By utilising these parental breeds foundation crosses (both ovals and dumbbells) were made and subjected for evaluation under the ambient conditions of West Bengal. Based on the overall performance few oval and dumbbell foundation crosses were identified.
