Abstract

Rice (Oryza sativa L.)  is a major staple known for fulfilling our dietary requirements. Continuous breeding efforts for widening its genetic base are essential to develop climate-resilient varieties in the future. In view of this, a stability analysis among 81 genotypes comprising of traditional landraces and released varieties was done to evaluate their yield-attributing traits across three seasons namely, Kharif 2022, Rabi 2023, and Kharif 2024. The AMMI and GGE biplot exhibited seven genotypes viz., KRG 45 (Sithiraikar), KRG 33 (Kulipadichan), KRG 21 (JGL), KRG 40 (Norungan), KRG 46 (Sivapu Kavuni), KRG 2 (Aanaikomban) and KRG 12 (CO 51) as the stable genotypes with high yield across seasons. Considering the per se performance for yield, KRG 2 and KRG 46 had the highest yield across seasons than the two checks viz., CO 51 and CO 55. Among the three seasons, Kharif 2022 was found to be ideal and exhibited a favorable influence on the genotypes for yield. Since, the three seasons were found to interact independently on the genotypes, they could be used to evaluate the upcoming breeding trials for testing stability in rice. The identified stable genotypes from this study could be advanced for further evaluation to develop climate-resilient rice varieties in future.
