Abstract


Abstract: In present investigation Line x Tester analysis was carried out to estimate heterosis (heterobeltiosis, average and standard heterosis) for identification of superior hybrids.Crosses attempted using 25 biofortified testers and two A1 cytoplasm based male sterile lines during summer 2022-23.The resultant Fifty hybrids along with two male sterile lines, 25 testers and three checks viz., VPMH 7(Local check), VPMH 14(Local check) and Kaveri Super Boss (commercial private check) were planted at Regional Agricultural Research Station, Vijayapura during kharif, 2023 and evaluated for yield and yield components. Seven hybrids exhibited significant positive standard heterosis over check VPMH 7, one hybrid displayed substantial positive heterosis over the local check VPMH 14 and commercial private check Kaveri Super Boss for grain yield. In addition, hybrids ICMA 98222 × VJP Fe & Zn-9 and ICMA 98222 × VJP Fe & Zn-25 were found to be superior for dry fodder yield over check VPMH 7 which was found best check for dry fodder yield
