Abstract

Mutation is a suitable technique for growing the various strains of plants. Two local varieties (Tarom-Hashemi and Sang-joo) including three improved varieties (Nemat, Fajr and Jolodar), are treated with 200 gray of Gamma ray at Atomic Agricultural, Medical and Industrial School in Karaj. M₁ and M₂generation were planted in the GABIT experimental field and some agronomical and morphological traits of a single plant such as the number of grains per panicle, per unfilled panicle, panicle length, tillers number, grain length, grain width, 1000-grain weight and grain yield per plant were evaluated. The cluster analysis of each variety along with their M₁ and M₂suecesive generation indicated a vast range of variation among parents and their M₁ and M₂ generation, meaning 4 cluster groups for Tarom-Hashemi, Fajr and Nemat, 5 groups for Sange-joo and 6 groups for Jolodar. A comparison of the overall dendrogram has shown that the wide range of variation belonged to Jolodar, Sang-Joo and 4 other varieties, respectively.
