ABSTRACT

 

Okra or Bhendi is a crucial vegetable farmed in India. The state of Tamil Nadu contains a smaller cultivable area and less okra production. As a result, the investigative study was conducted at Sivapuri, Chidambaram, Tamil Nadu to estimate variability metrics such as PCV, GCV, and GA% mean for crop advancement studies. The experiment involved 48 okra genotypes and 12 qualitative variables. In accordance with ANOVA, the mean sum of squares of 48 genotypes was highly significant for all parameters tested. For the twelve studied traits, values of PCV was higher than values of GCV by a little margin, showing the influence of environmental influences on genotypes. High heritability was found in all characters except days to 50% flowering and days to first harvest. High genetic advance % of mean was perceived in all the traits except for days to the 50% flowering, the harvest period and days to first harvest. High heritability combined with high GA was recorded in traits like primary branches per plant, fruit girth, no. of fruits per plant, fruit length, and fruit yield per plant. If genotypes are chosen based on these traits, selection for genetic improvement programs would be highly efficient.
