Mutation breeding is one of the most important method for ornamental plants. Chrysanthemum genus that has richest mutant varieties in The objective this study to create variation by gamma irradiation and improving traits mutation breeding. For aim, vitro bud explants white Bacardi variety were irradiated radiation at 20 Gy (Gray). In subcultures continued until M1V4 period observations obtained...

Induced mutagenesis is best approach for creation of genetic variability but most of interest is paid towards crop plants with only a few exceptions. But even widely used medicinal plants could receive a little attention in this direction. Catharanthus roseus is an important plant medicinal plant yielding antihypertensive alkaloid ajmalcine and anticancerous alkaloid vincristine and vinblastine...

one of the traits of the greatest financial impact on sheep production is the number of lambs weaned per ewe with fecb considered as the most well known major gene concerned with this trait. in order to conduct a marker assisted introgression (mai) program the presence of fecb responsible mutation in afshari sheep breeding flock was surveyed. direct test to detect fecbb allele was conducted on ...

BACKGROUND Pituitary dwarfism in German Shepherd Dogs is associated with autosomal recessive inheritance and a mutation in LHX3, resulting in combined pituitary hormone deficiency. Congenital dwarfism also is encountered in breeds related to German Shepherd Dogs, such as Saarloos and Czechoslovakian wolfdogs. OBJECTIVES To investigate whether Saarloos and Czechoslovakian wolfdog dwarfs have t...

Mutation breeding is one of the breeding methods used successfully in durum wheat for selecting lines with increased agronomic values. This study was carried out to determine gamma rays effect and interaction between gamma-rays and the genotype of treated variety of winter wheat in mutations induction. We used physical mutagens: gamma-rays in doses 100, 150, 200, 250 Gy. Seeds of eight winter w...

As a common mutation trait in plants, leaf colour is related to the degree of chlorophyll and anthocyanin changes destruction chloroplast structure. This study summarizes latest research progress mechanism, including metabolic basis plant mutation, caused by gene metabolism pathway, blocked development, controlled key transcription factors non-coding RNAs, environmental factors, due involvement...
