Studies on Brinjal Hybrids Evaluation: Glimpse on F1 Hybrid Evaluation

The first generation hybrids can be well exploited in view of the advantages such as uniformity, earliness and higher yield. Twenty five brinjal F1 hybrids collected from diverse sources viz., SAU?s, ICAR and Private Institutes were assessed for yield and quality characters. Based on the mean performance and standard heterosis the hybrid COBH-1 was found to be promising one with respect to growth, earliness, marketable fruit yield and quality traits. Estimates of genetic coefficient of variation for fruit weight, number of fruits, marketable fruit yield and total phenols content indicated the major part of variability was due to genetic constitution. Higher values of heritability coupled with genetic advance were observed for the above traits, suggested these traits are possibly controlled by additive genes; hence yield improvement relied upon them. Association of characters indicated the highest contribution towards fruit yield was given by number of branches followed by percentage of long styled flowers. Path analysis study revealed the highest direct effect on yield was contributed by number of fruits followed by fruit length and fruit girth.
