Rice (Oryza sativa L.) is major staple food crop in India as well as world. The experiment was conducted to study the comparative performance of elite early duration cold tolerant cultures under irrigated condition in hills and to identify the early duration high yielding genotypes. Totally 25 paddy genotypes evaluated in RCBD in two replications. The results indicating that all entries were found significantly early in days to fifty per cent flowering and maturity compared to KPR-1 except IET-28890. Significantly highest plant height recorded in the entries IET-28892 (98.25 cm) followed by IET-28891 (92.63 cm) and 28880 (91.38 cm). Significantly maximum number of panicle per plant was observed in IET-28880 (8.75) and the entry IET-28890 (4639 kg/ha) recorded significantly maximum grain yield/ ha compared to local check KPR-1. None of entries recorded low scores than the KPR-1 for leaf blast and neck blast and entries IET-28886, IET- 28887, IET- 28890, IET- 28893 and IET- 28895 recorded less infestation of leaf folder among the 25 entries. The entry IET-28890 is best performing and most promising entry under hilly conditions of Karnataka and it has great value in future breeding programme.
