Abstract
The present investigation was carried out to assess the performance of twenty four
parthenocarpic genotypes along with checks under net-house and open-field conditions during
rainy and spring-summer seasons of 2018-19 in brinjal. The genotypes, environments and
their interactions affected the performance of all the traits under investigation. In General,
most of the traits related to vegetative growth, flowering, fruiting and yield related traits
performed better under net house conditions as compared to open field conditions. Overall
performance for vegetative traits was the best in parthenocarpic genotypes PC-104-13-3, PC133-1,
PC-104-12-2 in both the seasons. The 93213-PC-2-3 and 93213-PC-2-1 were the
earliest for days to 50% flowering, days to harvest, had the highest the number of flower and
fruits per cluster as well as marketable fruits per plant in both the environments and seasons.
The highest fruit weight was observed in PC-104-13-1. The parthenocarpic genotype, PC123-1
had the highest marketable fruit yield per plant (2.89 kg) as well as fruit yield per acre
(346.38q) in net house during rainy season, while PC-11-2 had the maximum marketable fruit
yield per plant (1.27kg) fruit yield per acre (158.75q) in net-house during spring-summer
season. Among various traits, the number of flowers and fruits per cluster, days to harvest,
and number of marketable fruits per plant showed high GCV, PCV and heritability and can be
used for effective selection of parthenocarpic lines in adverse conditions also. Most of the
morphological traits were positively correlated with the yield potential of plant; however,
days to 50% flowering (0.995) under net house and average fruit weight (0.979) in open field
conditions in rainy season, average fruit weight (0.991) under net house and days to first
harvest(0.947) in open field conditions in spring summer season were highly correlated with
marketable yield per plant. Marketable yield and associated traits were affected with the type
of cultivation as well as season, where the parthenocarpic genotypes performed best in nethouse
conditions during rainy season cultivation.
