Appearance of Agronomic Characters and Genetic Parameters Estimation on M3 Population of Roselle [Hibiscus sabdariffa L.]

[摘要] The morphology of mutant putative plant population can be influenced by genetic factors and environmental factors. M3 generation population was thought to have wide character variability. The objective of this study was to determine the performance of agronomic characters and to estimate genetic parameters values of M3 generation in mutant populations of 150 Gy and 450 Gy. Seeds from mutant population 150 Gy and 450 Gy in M2 generation were harvested, and then their seeds were grown as M3 generation. Variations that were obtained of each character at generation M3 influences plants growth and development. The difference in character variability from the two mutant putative populations causes significant differences compared to the mean value character of control plants population. The heritability values of all characters observed range from low to high. Character canopy diameter and number of fruits per plant can be used as a character of selection in the next generation.
