Assessment of genetic variability for early seedling vigour, yield and its contributing traits in early duration genotypes of rice under direct seeded condition

Abstract

Eighty rice genotypes were assessed for different 26 early seedling vigour traits, yield and its component traits under direct seeded condition. The entire 26 early seedling vigour, yield and its component traits showed significant variation. Highest values of PCV coupled with GCV was recorded for number of unfilled spikelet, vigour index II, seedling dry weight on 30 DAS, seedling dry weight on 20 DAS, number of filled spikelet, grain yield per meter square. Based on grain yield, genotypes namely, R1004-2552-1-1 recorded high grain yield followed by Indira aerobic-1, Asam chudi, Surekha, IR 08 L 152, Pokali and Aditya.
