Physiological screening of released rice varieties for direct seeded condition

The field experiment was laid out in Randomized Block Design (RBD) with 35 genotypes including one check replicated twice. The result revealed that, the yield attributing characters viz. panicle length (26.25 cm), filled grains panicle-1 (153), number of panicles m-2 (391.5), grain yield plant-1 (36.10 g) and straw yield plant-1 (39.40 g) of rice is highest in Karjat 10. The screening revealed that Karjat 10 was best genotype under direct seeded rice condition because of its high yielding, non-lodging and non-shattering characters having maximum shoot length (33.10 cm), seedling vigour (3380.50), total dry matter plant-1 (90.50 g), relative water content (82.52 %), chlorophyll ‘a’ (2.700 mg/g FW), chlorophyll ‘b’ (0.688 mg/g FW) and total chlorophyll content (3.402 mg/g FW).
