INTEREST in the genetic effects of irradiation on quantitative characters usually takes the form of two questions. Does irradiation effect a genetic change in the mean of quantitative characters such as human intelligence? Does irradiation induce genetic variance in quantitative characters that could be utilized by the plant or animal breeder for genetic improvement? Experimental data relevant ...

This study was conducted to develop a novel herbicide resistance soybean using ethyl methanesulfonate (EMS) mutagen. In this study, 0.1% of EMS mutagen applied the [Glycine max (L.) cv Ar?soy] seeds. A single resistant mutant selected in M2 population evaluated under field and greenhouse conditions. The AHAS gene regions herbicide-resistant progeny were mapped, nucleotide changes defined confer...

This study was conducted to determine changes for some quality characters in M2, M3 and M4 mutated populations of three bread wheat genotypes irradiated by different gamma rays. The results showed that the significantly variably differed their response various traits at rays doses M3, populations. shifts per see from controls examined such as thousand-grain weight (TGW), test (TW), wet gluten c...

In order to improve the bioleaching efficiency of arsenic-rich gold concentrates, a mixed bacterial flora had been developed, and the mutation breeding method was adopted to conduct the research. The original mixed bacterial flora had been enrichedin acid mine drainage of Dexing copper mine, Jiangxi Province, China. It was induced by UV (ultraviolet), ultrasonic, and microwave, and their combin...

Abstract Crop genetic diversity has a significant role in improving new plants through breeding. The chrysanthemum contains the most mutant varieties, making mutation breeding one of widely utilized procedures for ornamental plants. goal this research is to use gamma irradiation induce variation and improve features. In vitro bud explants white ‘Bacardi’ type were treated with rays at 20 Gy on ...

Peach is an economically important fruit tree crop worldwide. The external color of the governs peach price, especially in fruits with different degrees blush. Molecular marker-assisted breeding has become a necessary part modern practices, increasing their efficiency. Although key related genes responsible for peel coloration have been found peach, corresponding molecular markers not widely us...

Bud mutations often arise in citrus. The selection of mutants is one of the most important breeding channels in citrus. However, the molecular basis of bud mutation has rarely been studied. To identify differentially expressed genes in a spontaneous sweet orange [C. sinensis (L.) Osbeck] bud mutation which causes lycopene accumulation, low citric acid, and high sucrose in fruit, suppression sub...

Osteogenesis imperfecta (OI) is a genetic disorder causing defects in the development of collagen type I. Clinical signs of affected dachshunds include multiple fractures of bones, joint hyperlaxity and dentinogenesis imperfecta. Recently, a recessive mutation in the SERPINH1 gene was detected in dachshunds and enabled the development of a DNA test to identify dachshunds carrying the mutation. ...
