An AICRIP (Rice) experiment was conducted at Agricultural and Horticultural Research Station, Ponnampet and the objective of the experiment is to study the comparative performance of elite early duration cold tolerant cultures under irrigated condition in hilly condition. The experiment consists of 14 cultures, which were evaluated in two replications in Randomized Complete Block Design (RCBD) fashion. Observations on days to fifty percent flowering, plant height, number of panicle per plant and grain yield were recorded and cultures were also scored for leaf and neck blast by following SES scale of IRRI (1996) in the nursery and field condition respectively. The results showed that the culture IET-26573 recorded low scores for both leaf and neck blast, IET-26576 (80 days) for significant earliest days to 50 % flowering, the IET-25818 (70.50 cm) and IET-26573 (71.50 cm) for the significant dwarf plant height, IET-26563 (469.33) for significantly higher number of panicles per square meter and where as the culture IET-25826 recorded significant highest grain yield (5798 kg/ha) compared to all genotypes and which is recorded 5.34 % more grain yield over the best and local check variety Tunga (IET-13901). The culture IET-25826 in this trial is most promising in terms of grain yield (Kg/ha) and neck blast compared to all elite cultures and the local check variety Tunga.
