This study presents a comparative analysis of rice genotypes based on yield components and vegetation period. The experiment was conducted in a selection nursery using the Gulistan standard variety as a control. The evaluated traits included plant height, vegetation period, panicle length, productive tillering, number of grains per panicle, 1000-grain weight, and single-plant productivity. The results showed that several genotypes outperformed the standard variety in key yield components. In particular, D-40(D-37)(D-143) and D-260(D-179)(D-136) were identified as promising breeding materials. A clear relationship between vegetation period and yield components was observed.
