Heterosis studies over environments in chilli (Capsicum annuum L.)

2001

A:PS

The estimates of heterosis were determined based on the mean performance of chilli (C. annuum) hybrids, developed from crossing 3 lines (Jwala, S-49, and G-4) and 8 testers (Jagudan-103, Gujarat Chilli-1, Resham Patti, Kumathi, SG-5, Anand Chilli-1, DPS-120, and ACS 92-1), for yield and yield components (days to flowering, plant height, number of primary branches, number of fruits per plant, fruit length, fruit girth, fruit weight, days to fruit ripening, and fruit yield per plant) during 1997 and 1998 in Anand, Gujarat, India. The cross S-49 x DPS-120 exhibited significant standard heterosis (15.30%) for green fruit yield. However, the maximum relative heterosis (92.04%) and heterobeltiosis (85.38%) for green fruit yield was observed in cross G-4 x Anand Chilli-1. Negative estimates of heterotic effect for most of the characters may be attributed to intra-allelic interactions. Heterosis breeding and development/conversion of male sterile lines with genetic background of adapted cultivars is suggested.
