Abstract:
In the development of brinjal hybrids, heterosis has been extensively used. Despite the fact that India is a significant producer with a diverse range of brinjal varieties, it lags behind other nations in terms of productivity, owing to a lower utilization of hybrids than other countries. The present investigation was carried out at Experimental Farm, Department of Vegetable Science, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan-173 230 (HP) during Kharif 2019. Eight parents (Six lines and two testers) were selected on the basis of divergence and mated in line × tester design to measure heterosis for different yield attributes. The check used for the estimation of standard heterosis was PBH-4. All the resultant twelve hybrids exhibited wide variation among them for different characters under study. Most of the hybrids exhibited positive heterobeltiosis and standard heterosis in desirable direction. Among lines IVBL-116-131, DBR-8 and Jawahar Brinjal; and among testers PPC was the best general combiners for yield and yield attributing characters and hence these lines can be used in multiple crosses and their segregating population. Based on heterosis per cent, most promising cross combinations were DBR-8 × PPC, IVBL-116-131 × PPC, IVBL-116-131 × PPL and Jawahar Brinjal × PPC which performed well for majority of traits. Hence, these hybrid combinations can further be tested at multiple locations and could be utilized for future hybrid brinjal breeding.
