Abstract:

The present investigation was assessed using 100 F2 individuals, their parents and F1 for characters days to flowering, plant height, panicle length, productive tillers per plant, number of grains per panicle, grain yield per plant, straw yield per plant and harvest index. These traits are most important for identification of good segregating plants or genotype. Here, in the present study F2 population was developed from the cross between GAR-13 (improved and high yielding cultivar) and Lalkada (local landrace). Regarding the population distribution analysis, only number of grains per panicle and straw yield per plant was showed normal distribution in segregating population while other characters did not show normal distribution in the population. Productive tillers per plant, grain yield per plant and harvest index considered to be governed by complimentary gene interaction and days to flowering, plant height and panicle length was governed by duplicate gene interaction.
