Title : Diverse inbred lines with better fruit traits improves earliness and yield traits in eggplant (Solanum melongena L.) in Malabar Coast of India

Abstract :

Despite the large variability in brinjal germplasm for several growth, fruit traits, bioactive compounds and mineral nutrients in India, low productivity with late fruit harvesting remains the major hurdle in brinjal cultivation. The best way to utilize the heterosis in crop is to generate F1 hybrids with maximum heterozygosity, which leads to the identification and selection of hybrid vigour. The maximum standard heterosis for yield per plant was observed in the cross L5 × T3 (25.30%, Raidurg Local × Pusa Purple Cluster) followed by L2 × T1 (23.35%, IC-433678 × IC-89986), L2× T3 (23.26 %, IC-433678 × Pusa Purple Cluster), L1 × T3 (9.77%, IC-345271 × Pusa Purple Cluster) and L4 × T3 (7.44%, Tiptur Local × Pusa Purple Cluster). The hybrid L5× T3 (Raidurg Local × Pusa Purple Cluster) also exhibited high significant standard heterosis for long styled flowers (37.16%), number of fruits per plant (26.13%), fruit weight (18.68%) as well as earliness traits like days to first harvest (-16.75%) and days to last harvest (-26.87%). The hybrid L2 × T3 (IC-433678 × Pusa Purple Cluster) showed significant standard heterosis for days to first flower (-9.15%), long styled flowers (31.04%), number of length of fruit (18.57%) and fruits per plant (4.21%). Therefore, these hybrids could be identified and released for multilocational trials to the growers to fetch early price and higher yield in brinjal with consumer specific preferences.
