ABSTRACT An experiment was conducted during Summer and Kharif 2021 at AICRP on seed (Crops), UAS, GKVK, Bengaluru to evaluate seed quality parameter of rice (Oryza sativa L.) varieties under aerobic condition. Among the selected varieties for cultivation under aerobic condition the highest seed germination (97.67 %), seedling vigour index-I (2844), total dehydrogenase activity was (1.408 A480nm g-1) and lower seed mycoflora (0.17 %) were recorded in variety Jaya. Similarly, maximum speed of germination (32.58), higher mean seedling dry weight (97 mg) and highest seedling vigour index-II (9474) were recorded in variety MAS-26. However, mean seedling length (30.65 cm) was highest in KMP 220. Meanwhile, higher shoot to root ratio (0.54) and lower electrical conductivity (38.29 µS cm-1 g-1) was more in MAS-946-1. Whereas, lowest seed germination (83.17 %), speed of germination (24.57), seedling vigour index-I (1912) were recorded in Pustic-1; lower mean seedling length (22.2 cm) and mean seedling dry weight (50.5 mg) were observed in IR-30864There was significant variation for seed quality parameters among the studied varieties.
