ABSTRACT
The study was conducted at the Department of Biotechnology and Genetic Engineering, Islamic University, Kushtia, Bangladesh during April, 2019 to October, 2020. Rice is the edible seed of the grass species known as Oryza sativa. This cereal grain is a staple food for a significant portion of the world’s population and serves as a vital source of nutrition and calories in many cultures. Rice can be found in various varieties, each with distinct characteristics and uses, making it a versatile and essential crop in global agriculture and cuisine. Chinekani is a local rice variety with proper nutrition and pleasant aroma, which is cultivated in Satkhira district in Bangladesh. Morphpo-phisiological traits like Chlorohyl and carotenoid and yield related character, different mutants (M-1 generation) were planted in field and observed till harvesting. In M2 generation, significantly increased leaf area, meaningful tiller number per panicle and grain per panicle as well as reduced height (important feature of lodging resistance) was found among mutants. Beneficial traits from these mutants can be exploited for future rice breeding programs. Novel mutant alleles and their functional gene expression analysis employing reverse genetic tools were discovered using these germplasms.
