SCREENING OF BRINJAL GENOTYPES TO IDENTIFY GENETIC RESOURCES WITH HIGHER YIELD AND YIELD ATTRIBUTES

Abstract

The present study was conducted for morphological evaluation of 65 brinjal genotypes at the research field of Bangladesh Institute of Nuclear Agriculture (BINA), Mymensingh. Morphological characterization, performed as per the minimum descriptors as prescribed by IBPGR, revealed wide and significant variations for most of the traits investigated. In terms of individual fruit weight, the heaviest fruits were obtained from the genotype SM17 (251.78 g) followed by SM6 (221.56 g), whereas the lightest fruits were found in genotype SM58 (50.78 g). At 120 days of planting (DAP), the longest and shortest plants were recorded from the genotypes SM44 (73.67 cm) and SM24 (31.22 cm), respectively. Most importantly, the highest yield (58.34 t ha-1) was recorded from the genotype SM28 followed by SM6 (56.95 t ha-1). By contrast, the genotype SM46 yielded the lowest (8.36 t ha-1). Among the 65 genotypes studied, 13 promising genotypes (SM1, SM5, SM6, SM7, SM11, SM16, SM17, SM21, SM28, SM33, SM42, SM54 and SM56) were selected based on yield and other quality attributes, namely colour, shape, size, texture and glossiness.
