Abstract: Heterosis breeding has proven to be a potential method of increasing yield in the crops. It enables early identification of superior/potential crosses which is necessary to handle the material in advance generations, effectively and gainfully. An experiment was conducted to evaluate 35 genotypes in four different environments at Navsari Agricultural University. The experimental material consisted of 35 genotypes; representing 24 hybrids developed in line x tester mating of 10 diverse parents and commercial hybrid check ‘OH-102’. Significant and high estimates of standard heterosis were observed for fruit yield/plant in all environments. Among the hybrids, AOL-16-04 x Parbhani Kranti was consistent with respect to higher heterotic effect for fruit yield/plant across the environments, while cross AOL-16-04 x Arka Anamika was consistent for heterotic effects in environments E1, E2 and E3 and the cross NOL 17-09 x Arka Anamika was consistent in E1, E3 and E4 for fruit yield/plant. These crosses may be exploited for commercial cultivation and may also be advanced as those would likely yield superior transgressive segregants.
