Vererbung des β‐Glucangehaltes der Haferkaryopse

Vererbung des β‐Glucangehaltes der Haferkaryopse Inheritance process for β‐glucan content in oat caryopsis Due to the fact that there are only few studies concerning β‐glucans in oat caryopsis with regard to plant‐breeding aspects, three oat crosses were performed (cross 19 = low × high, cross 86 = low × low, cross 98 = high × high). In all of the three oat crosses, lower β‐glucan content (% DM) was recorded in F, than in F, indicating that the β‐glucan content (% DM) at a higher heterozygoty grade is lower than at a reduced heterozygoty grade. This points to a dominant inheritance of lower β‐glucan content (% DM). A tendency towards the female β‐glucan content (% DM) could not be proven. Thus, it can be started from a nuclear genetic inheritance of the β‐glucan content (% DM). In most cases, the experiments showed a normal distribution of β‐glucan content (% DM), indicating for several genes a quantitative inheritance of β‐glucan content (% DM). By means of the regression of the F3‐lines to the F2‐plants, the narrow‐sense heritability could be calculated for the cross 86 (h2= 0.51***) and the cross 98 (h2= 0.48***). The heritability for the cross 19 was not significant. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Agronomy and Crop Science Wiley

Abstract

Inheritance process for β‐glucan content in oat caryopsis Due to the fact that there are only few studies concerning β‐glucans in oat caryopsis with regard to plant‐breeding aspects, three oat crosses were performed (cross 19 = low × high, cross 86 = low × low, cross 98 = high × high). In all of the three oat crosses, lower β‐glucan content (% DM) was recorded in F, than in F, indicating that the β‐glucan content (% DM) at a higher heterozygoty grade is lower than at a reduced heterozygoty grade. This points to a dominant inheritance of lower β‐glucan content (% DM). A tendency towards the female β‐glucan content (% DM) could not be proven. Thus, it can be started from a nuclear genetic inheritance of the β‐glucan content (% DM). In most cases, the experiments showed a normal distribution of β‐glucan content (% DM), indicating for several genes a quantitative inheritance of β‐glucan content (% DM). By means of the regression of the F3‐lines to the F2‐plants, the narrow‐sense heritability could be calculated for the cross 86 (h2= 0.51***) and the cross 98 (h2= 0.48***). The heritability for the cross 19 was not significant.
