gamma irradiation was used at different doses (80, 160 and 240 gy) on glycine max (l.) merrill cv. hill homogenous seeds. a single suitable m2 plant was selected and evaluated at m3 and m4 along with its parent and three other varieties as control in rcbd experiment in sari agricultural sciences and natural resources university’s experimental field. m-80-709 and m-160-3429 mutant lines were sig...

The main objective for plant breeding is to increase genetic diversity. Mutation induction is a method to increase genetic diversity associated with selection, recombination, or a combination of these approaches in plant breeding. The present research was aimed to compare efficacy of different doses of Gamma rays (150, 200, 250, 300 and 350 Gy and zero dose control) on the sesame morphological ...

Few sweetpotato (Ipomoea batatas Lam.) cultivars with erect plant type are available despite their advantages over spreading type, such as simplicity of cultivation and ability to adapt to limited space. One of the reasons is insufficiency of their agronomic characteristics for table use. So, it is important to overcome these drawbacks of ER-type lines. We attempted to breed new erect plant typ...

Genetic diversity in strawberry is low due to its asexual propagation. One method of increasing genetic diversity, as an important tool in plant breeding, is the use of gamma rays to induce mutation. In order to determine the appropriate dosage of gamma irradiation for genetic diversity creation by mutation in strawberry, Kurdistan cultivar, and to study the influence of various doses of gamma ...

Mutation breeding as an alternative to conventional breeding, is commonly used to improve current varieties and to generate new varieties. Genetic variation in rice is very low, because of its self-pollination. This study, carried out to determine the GR50 dosage for an irradiation mutagenesis study on the rice and to determine the effects of gamma irradiation on germination and growth rate of ...
