Short Mutant Characters and Early Maturing of M4 Generation of Local Rice Ase Buluh, Gamma Radiation Results

Abstract

A research on the mutan character of the local rice for M4 generation Ase Buluh, gamma ray radiation has been done with dose 0 gray, 200 gray and 300 gray of local rice germplasm in Pangkep South Sulawesi Indonesia. It aims to determine the morphological characteristics and agronomic mutants early maturity and short growth local rice Ase as results of gamma radiation. This study uses a simple randomized block design (RAK). The results showed that the morphological characters with gamma radiation dose of 300 Gray showed that the average plant height is 135.31 cm shortest and the least number of productive tillers is 13.63. Likewise for agronomic observations which the radiation dose of 300 Gray showed the age of flowering and harvesting is fastest respectively 81.37 days and 120 days. The benefit of this research was to obtain mutants and growth of early maturing short-lived and will obtain varieties that can be maintained continuity.
