Abstract
A field experiment was carried out during 2017-18 at Department of Vegetable Science, College of Horticultural, Bengaluru to study the performance of advanced breeding lines of brinjal for bacterial wilt disease resistance, yield and quality attributes. The experiment was conducted separately for green long and green round genotypes of brinjal. Fourteen green long genotypes were evaluated in two replications in randomized complete block design along with parents (Green Long and IIHR-3) and checks (Arka Kusumakar and Arka Anand). In green round segment, ten genotypes along with parents (RGR and WCGR) were evaluated in three replications in randomized complete block design. In green long segment, highest yield (836.11g per plant) was obtained in the genotype 170-9-26, maximum number of branches per plant (6.56) were noticed in 170-19-26, least number of days to first and fifty per cent flowering (36.70 and 42.90 days respectively) in 46-6-4, maximum number of fruits per plant (26.31) in 170-19-26, highest average fruit weight (38.58 g) in 170-9-30, maximum fruit length (15.80cm) in 46-3-32, and maximum fruit width (3.10cm) in 170-9-11was observed. In green round segment, highest yield (754.64g per plant) was obtained in the genotype 30-2-7, maximum number of branches per plant (6.82) was noticed in 249-10-29, least number of days to first and fifty per cent flowering (37.53 and 44.30days respectively) in 30-1-42, maximum number of fruits per plant (20.44) in 30-2-12, highest average fruit weight (46.13g) in 30-1-18, maximum fruit length (5.80cm) in 30-1-41 and maximum fruit width (4.27cm) in 30-1-18 was noticed. Nine (46-3-32, 46-3-35, 170-11-1, 170-11-11, 170-9-11, 170-9-30, 170-9-15, 170-9-19 and 170-19-26) and five (30-2-7, 30-2-12, 30-1-7, 249-10-29 and 249-10-54) advanced breeding lines were resistant to bacterial wilt disease in green long and green round segments respectively. With respect to quality parameter, phenol content in fruit was lowest in the genotype 170-9-19 (2.02 GAE mg/g) among green long segment and 30-1-41 and 249-10-54 (1.55 GAE mg/g) among green round segment.
