Ultrastructure and genetics of the barley line Hiproly

Abstract

Seeds from the high lysin, high protein barley line Hiproly and the low lysin, low protein line Jcy 124 were compared by means of a scanning electron microscope. Differences were found in the development of the subaleurone layer and the distribution of the starch granule diameter. To study the inheritance of high lysin and crude protein in seeds as well as other parameters, crosses were conducted between the two lines. High lysin was found to be due to a single recessive gene, linked to the gene for short rachilla hairs, whereas crude protein was quantitatively inherited. As the F3‐families were also scored for heading date, grain yield per plant, total weight per plant and 100‐grain weight, the coefficient of correlation between all pairs of characters were computed. For crude protein — grain yield and lysin — grain yield the coefficients were — 0.48*** and — 0.45***, respectively. © 1974 Mendelian Society of Lund
