Abstract:
Rice is one of the most important cereal food crops and the primary source of livelihood for about half of the global population. Out of twenty hybrids tested, highest grain yield of 71.8 q ha-1 was recorded in NPH 8899. This treatment also showed 331 tillers /m2, plant height of 109.5 cm, Days to 50% flowering of 86 days, panicle length of 26.4, effective grains panicle-1 of 243.8, per panicle weight of 6.47 g. This treatment was followed by PAC 835 which recorded grain yield of 67.7 q ha-1, number of tillers /m2 of 309, plant height of 107.9 cm, per panicle weight of 5.64 g whereas, the check hybrid, PA 6444 recorded grain yield of 65.8 q ha-1, number of tillers /m2 of 299, plant height of 112.7 cm, Days to 50% flowering of 96.7 days, panicle length of 26.9, effective grains panicle-1 of 238.8, per panicle weight of 5.15 g. Out of twenty hybrids, only three hybrids i.e., Arize Tej, DRH 834 and JKRH 401 showed moderately resistant reaction against false smut of rice under artificial condition of inoculation. The hybrids, DRH 834, JKRH 401 and Arize Tej recorded panicle affected with false smut disease of 3.3%, 4.3% and 5.0%, respectively. Whereas, the hybrids, Arize Tej, DRH 834 and JKRH 401 gave grain yield of 59.8, 53.3 and 62.7 q ha -1 respectively.
