Abstract:
The present study was conducted using six hybrids generated from ten diverse lines at Main Vegetable Research Station, Anand Agricultural University, Anand. The observations were recorded for total fourteen characters. Cross 2017/TODVAR-8×2015/TOLCV RES-I exhibited highest estimated of relative heterosis, heterobeltiosis and standard heterosis. Highest inbreeding depression was also recorded for the same cross. Highest values of RH, HB and SH for average fruit weight and lycopene content were recorded for 2017/TODVAR-8×2015/TOLCV RES-I. Based on the present findings, 2017/TODVAR-8×2015/TOLCV RES-I should be utilized for heterosis breeding and can be used to further in advanced breeding programmes.
