Abstract:

Rice (Oryza sativa) delivers an essential food basis for more than half of the world's population. A surge in yield can significantly contribute to international food security. Hybrid rice breeding can potentially help to encounter this area because hybrid rice frequently shows a significant rise in yield when paralleled with modern inbred varieties. This study was undertaken to evaluate the different combinations of test hybrids. The main objective of the trial was found high yielding rice hybrids with acceptable cooking quality of rice. Five different rice test hybrids were evaluated named KSK165H, KSK168H, KSK169H, KSK171H, and KSK153H yielded 84 t/ha, 90t/ha, 96 t/ha, 98t/ha and 110t/ha in nonreplicated yield trial. Other morphological yield contributing traits no grains per panicle ranges from 215 to 245, tillers per plant were 14-19, and thousand grain weight was from 23-26g. Cooking quality of all these tested hybrids is Average grain length (AGL) ranges from 6.2mm to 6.7 mm while cooked grain length (CGL) 13.5mm-16mm, head rice recovery of these hybrids 65-72%. Locally produced hybrids were high yielding and their yield ranges 80-110 t/ha with better cooking quality. These hybrids were subjected to National Uniform Yield Trials 2023-24 for further testing and evaluation for certification and registration process. If these rice hybrids will be approved by the certification department all the imported hybrid quantity of about 10,000 metric tons cost 17.5 million USD invested in import of rice hybrids from China will be reduced in national economy.
