Abstract
Germplasm collection was started from May to November, 2015. And total forty two eggplant germplasm were collected from in and around the country having wider range of geographical conditions. The experiments were started from May, 2016 to April, 2017 (Monsoon & Post-monsoon seasons) at Department of Agricultural Research (DAR), Horticulture Research Section Field, Yezin, Nay Pyi Taw, Myanmar. The experiments were laid out in a randomized complete block design (RCBD) with three replications. All of the collected genotypes were distributed around the collected regions and states. Mandalay Region and Kachin State (each 6 genotypes) represented more of the genotypes than other states and regions. The PCV and GCV were comparatively high (during both seasons) for fruit weight, days to first flowering, plant height, fruit length, petiole length, fruit breadth, leaf width, and leaf length. For both seasons, very high heritability estimates were obtained for days to first flowering, fruit weight, fruit length, fruit breadth, plant height, leaf length and leaf width. The traits like fruit weight, days to first flowering and plant height and their positively correlation traits were emphasized on future breeding program. The existence of a significant negative correlation between days to first flowering and fruit hardness with leaf traits and fruit length suggests the existence of a physiological limit among these traits. The genetic components of the correlations were more important than the environmental, as the phenotype is a reflection of the genotype. The fruit weight, days to first flowering and plant height in the yield component with greatest importance in genetic improvement in eggplant.
