CHARACTERIZATION, GENETIC DIVERSITY AND TRAITS ASSOCIATION OF EGGPLANT GERMPLASM

Abstract

Fourty (40) genotypes of Brinjal were studied in the experimental field of Olericulture division of Horticulture Research Centre (HRC) of Bangladesh Agricultural Research Institute, Gazipur, during September 2018 to March 2019. There was significant variation observed for all the characters within genotypes. Multivariate analysis was performed through principal component analysis(PCA), principal coordinate analysis (PCO), canonical variate analysis(CVA) and cluster analysis(CLSA). As per PCA, D 2 and cluster analysis, the genotypes were grouped to five clusters. The highest inter-cluster distance was between cluster I and IV and lowest between II and III. Cluster IV showed the maximum intra-cluster distance and I showed the lowest. Regarding agronomic performance, different characters contribute increasing the higher yield of brinjal. The height cluster yield mean observe from cluster I which include genotype SM 359, SM 362, SM 364, SM 367, SM 378 used as advance line. This advance line further used for development of high yielding OP (Open pollinated) variety in future. Due to the higher inter cluster distance, the genotypes BARI Begun-6 from cluster I, SM 359, SM 362, SM 364, SM 367, SM 378 from cluster II and SM 323, SM 351, SM 365, SM 373, SM 387, SM 393, SM 398, SM 399, BARI Begun-7, BARI Begun -8 from cluster IV would be suitable for efficient hybridization programme.
