| Popis: | 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 M2 generation 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 M2 suecesive 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. |
