Genetic suppresion of shrunken endosperm and low hordein content in Ris? mutant 18 (Hordeum vulgare L.)
Languages of publication
Data on segregation of the lys 3 b gene in the offsprings of crosses between the mutant Ris? 18 and the barley forms with plump kernels and high hordein content are presented.Hordein phenotype, and indirectly lysine, were determined by visual screening method.In the analysed materials all plump kernels were high-hordein (low lisine), and all shrunken kernels were low hordein (high-lysine).Genetic analysis showed a 3:1 Mendelian phenotypic ratio of normal and mutant F2 kernels in most of the analysed crosses.
