Induction of mutations with gamma ray radiation to improve the characteristics of wheat [Triticum aestivum L.] genotype IS-Jarissa

Abstract

Wheat [Triticum aestivum L.] is one of the strategic food crop commodities in Indonesia. Efforts to develop wheat continue to meet growing domestic needs. The aim of this study was 1] to obtain information on effective irradiation doses to obtain genetic diversity and diversity of morphological growth in wheat, 2] obtain information about the desired target mutants, which have early maturing and high-yielding wheat characters. The research began by irradiating the IS-Jarissa genotype wheat seed while looking for an effective dose of irradiation to change the genetic composition of wheat. Furthermore, planting mutants 1 [M1] and early mutant selection were conducted on M2. The results showed that: 1] IS-Jarissa wheat varieties were able to live on irradiation with a dose of 0 Gy, 100 Gy, 200 Gy, 300 Gy, and 400 Gy. 2] There were 21 mutant candidates in the M2 stage.
