Evaluation and identification of stable chickpea lines for yield contributing traits from an Association Mapping Panel

Abstract

An association mapping panel consisting of 380 genotypes of chickpea was evaluated for three different years viz. 2014-15, 2015-16, 2016-17 for yield contributing parameters viz., plant height, days to flowering, days to maturity, pod number per plant, seed number, 100 seed weight and plant yield. The AMMI analysis was performed mainly on seed weight and seed number which are the two most important yield contributing traits. The genotypes contributed 93.08 per cent of the total variance while the interaction effect was comparatively low with 4.1% for the two traits. AMMI analysis selected and identified genotypes IG5986, IG5982, ILC6025 and ICCV14307 as most desirable genotypes for seed weight and genotypes IG5893, ILC6891 and IG5856 for seed number. Identifying stable genotypes would help in strategic planning for yield improvement through component trait breeding.
