Abstract


An experiment was carried out with twenty lines and three testers to develop green fruited brinjal F1 hybrids with cluster bearing habit, striped fruit, shoot and fruit borer resistance and high yield. The lines and testers were raised in the crossing block and crossing was carried out in L x T mating design and hybrid seeds were obtained. Among the sixty hybrids developed, six hybrids with high yield and shoot and fruit borer resistance were identified and raised in the field and their growth, yield, shoot and fruit borer resistance were studied. Based on mean performance, the parent L15 was found to be the best for plant height, no. of fruits, fruit yield and marketable yield with less borer infestation. Among the hybrids, the maximum number of fruits (54.8) was recorded in the hybrid L15 x T2 followed by L2 x T2 (43.4) and L16 x T2 (42.2) respectively. The maximum per plant yield of 4.2 kg/plant was recorded by the hybrid L15 x T2. The hybrid L2 x T2 stood in the second place by recording 3.6 kg and L16 x T2 was in third position with a yield of 3.4 kg. The minimum borer infestation of shoot (12.0 %) was recorded in the hybrid L15 x T2 followed by L2 x T2 (12.4 %) and L12 x T2 (12.9 %). The minimum borer infestation of fruit (13.0 %) was recorded in the hybrid L15 x T2 followed by the hybrid L12 x T2 (13.8 %). Among the F1 hybrids, the performance of L15 x T2 was superior for growth and yield characters. The shoot and fruit borer damages were also recorded at lower level in the same hybrid.
