Comparative analysis of stability models for identifying rice inter-subspecific breeding lines adapted to different temperature regimes for exploitation in hybrid breeding.

ABSTRACT: Rice is a staple food crop in Tamil Nadu, cultivated in diverse ecosystems ranging from river delta plains to the Nilgiris hill valleys. The alarming climate change events are predicted to affect rice crop productivity across the globe. In this study, 76 newly developed breeding lines from inter-subspecific crosses, two commercial restorers, and checks were evaluated in four different temperature regimes of Tamil Nadu. Various stability methods were used to analyze genotype-environment interactions to identify lines with stable performance even under various temperature conditions. The stability methods applied in the study were classified under three models viz., the Uni-trait Stability Selection Model (Model - 1), the Uni-trait Mean Performance Stability Selection Model (Model - 2), and
