Variability and Heritability of Sigah Brown Rice Mutants (M3) in Vegetative Phase

This research aims to obtain information on genetic diversity, variability, and heritability of Sigah brown rice mutants (M3) in the vegetative phase. This research is conducted from March to September 2018 in the irrigation area of Sungai Sapih, Kuranji, Padang, where the area is 48 meters above sea level. The materials used in this study are M2 rice seeds (13 early maturing mutant lines and 10 tall plant mutant lines + number of tillers), and the original plants of Sigah genotype as a comparison (control). The analysis of genetic diversity, heritability, and variability are tested on plant height, number of productive tillers, and percentage of productive tillers. The selection method used in this study found that there are 8 early maturing mutants and 7 tall plant mutants + number of tillers. The line of early maturing mutants number 89 and 76 have wide diversity range in the term of the character of plant height, number of tillers, and number of productive tillers in the vegetative phase. Further, line 4, 19,134 of tall plant mutants + number of tillers have a wide variety of tillers too.
