Morpho-physiological studies in brinjal (Solanum melongena L.)

An investigation was conducted using twenty-two brinjal genotypes during Kharif 2024 to assess the morpho-physiological, growth and yield parameters of Brinjal genotypes. The experiment was laid out in Randomized Block Design in two replications. The morphological, physiological, phenological and growth-related observations were recorded at 45, 60 and 75 DAT. The yield and yield attributing characters were recorded at harvest, replication and treatment wise. The genotype AKBR-20-13 recorded highest plant height and genotype AKBR-20-01 recorded lowest plant height. Leaf area had increased from 60 DAT to harvesting. The genotype AKBR-20-13 showed highest leaf area at all the growth stages and the genotype AKBR-20-05 recorded lowest leaf area at harvest among the genotypes. The genotype AKBR-20-13 had the highest RWC and lowest canopy temperature at flowering stage, showing the potential trait for drought tolerance. The genotype AKBR-20-14 was required minimum days to 50% flowering. The genotype AKBR-20-13 and AKLB-9 recorded and higher SLW was an indication of moisture stress tolerance. The genotype AKBR-20-14 recorded highest no. of fruits per plant and genotype AKBR-20-06 recorded lowest no. of fruits per plant. The highest fruit yield per plant was recorded by the genotypes AKBR-20-14 and AKBR-20-23.
