Variation of Agronomic Characters of Rice Mutants Grown under Different Cultivation Conditions

Present studies were carried out to clarify the variation of agronomic characters of rice mutant lines when grown under different cultivation conditions. In general the variations of culm length, panicle length, number of days to heading, number of panicles per ㎡, number of grains per panicle, and weight of 1,000 grains of mutant lines were found to be more variable as compared with those of mother variety. In mutant lines as well as in the mother variety, the variability of panicle number per unit area and grain number per panicle was high, while the other agronomic characters showed comparatively low variability. No correlation was found among various agronomic traits when grown under conditions above-mentioned.
