Inheritance of awn barbing in two barley crosses

Inheritance of awn barbing in two barley crosses

Agron Jour 49(10): 558-560

The inheritance of awn barbing was studied using F2 and F3 populations of 2 barley crosses. A smooth-awned selection, Mich. 832-1188, was crossed with Bay, a semi-smooth awned type, and with Kindred, a rough-awned variety. Classification of segregates from the Mich. 832-1188 X Bay cross indicated that awn barbing in this cross was governed by a single dominant factor for semi-smooth awns possessed by the Bay parent. Results for the Mich. 832-1188 X Kindred cross were not explainable by independent assortment of genes. Data substantiated the hypothesis that 2 dominant linked genes from the Kindred parent were necessary for the expression of rough awns, while plants with only 1 of the 2 loci in the dominant condition were semi-smooth awned and those recessive at both loci were completely smooth-awned. A recombination value of 26.01% was calculated from the F2 data. The Mich. 832-1188 selection should be a valuable parent for use in the development of smooth-awned barley varieties. It is completely free of barbs from the base to the tip of the awn and is satisfactory in most agronomic characteristics. Transmission of the smooth-awn characteristic to segregates from crosses with Mich. 832-1188 should be easy to accomplish. It was demonstrated to carry the recessive alleles of the genes for barbed awns used in this study.
