This study was conducted to determine the magnitude of genetic relationships between fruit yield, yield components and quality traits in 37 okra genotypes for two years in order to bring quality breeding. Direct and indirect effects of fruit yield components on fruit yield per plant were investigated. Thirty seven accessions of okra were evaluated in randomized complete block design for various quantitative and quality traits and to quantify the relationships among these traits in diverse okra germplasm. Genetic analysis such as genotypic and phenotypic coefficient of variation and path coefficient analyses were performed. The results obtained showed highly significant variation in all the genotypes. Fruit yield/plant was significantly and positively associated with fruits/plant, average fruit weight and nodes/plant at both genotypic and phenotypic levels; which are important prerequisites to formulate a successful improvement program. Path coefficient analysis revealed that fruits/plant had the maximum positive direct contribution towards fruit yield/plant followed by average fruit weight and nodes/plant. The observed variability in the traits studied strongly indicate the possibility of selecting plants with suitable morphology when considering integration into any improvement programme towards preservation and conservation of okra germplasm.Keywords
