Combining ability heterosis and stability analysis in kharif maize Zea mays L

Abstract

An investigation entitled Combining ability, heterosis and stability analysis in kharif maize (Zea mays L.) was carried out with thirteen phenotypically different inbred lines (females) and three testers (male). These lines and testers were planted during rabi 2019-20 and crossed to produce 39 F1s using the lineand#61645;tester mating design. The 39 hybrids were evaluated alongside their 13 lines, 3 testers and 2 checks in a randomised block design with three replications at three locations during kharif 2020. The locations were (i) Bihar Agricultural College, Sabour (Zone-IIIA of Bihar); (ii) Irrigation Research Station Farm, Araria, (Zone-II of Bihar) and (iii) Betelvine Research Centre Farm, Islampur, Nalanda (Zone-IIIB of Bihar). newline
