Abstract:

The present investigation was carried out during Kharif 2017 at Regional Agricultural Research Station, Maruteru, Andhra Pradesh with an objective to screen the rice genotypes for their tolerance to anaerobic conditions during germination and also to identify varieties suitable for direct seeded rice cultivation, using two different methods, namely, test tube method and pro-tray method. The results revealed MTU 1140 to be superior with respect to germination percent, shoot length, root length and seedling dry weight in addition to seedling vigour index and anaerobic response index in both the screening methods and hence, the genotype is identified to be most promising for growing under direct seeded conditions. Among the screening methods, test tube method of screening is inferred to be more useful for evaluating large number of genotypes, while pro-tray method of screening is recommended for greater accuracy of the results.
