abstract
Rice (Oryza sativa L.) is the "global grain" of the world. The research was carried out at the College of Agriculture, IGKV, Raipur (C.G.), where 36 enhanced cultivars were assessed throughout the Kharif seasons of 2021–2022 and 2022–2023 to determine the effects of panicle architecture on grain yield among rice cultivars with varying durations. The experiment was conducted in a Randomized block design (RBD) with two replications. The panicle architecture and yield attributes traits viz., panicle length, average fertile and sterile grains per panicle and number of primary and secondary branches per panicle, Seed yield plant-1, and harvest index were noted during end at harvest during both years. The findings revealed that variety check MTU-1001, MTU-1224 (long-duration), MTU-1156, MTU-1155 (mid-duration), and MTU-1153, BINA-17 (short-duration) exhibited an average number of productive tillers, length of panicle, number of primary and secondary branches and a higher number of grains panicle-1, greater harvest index, they also had a lower incidence of sterile grains, resulting in higher economic yields compared to the other long, medium, and short duration rice varieties.
