THE INHERITANCE OF LOOSE SMUT RESISTANCE.: II. THE INHERITANCE OF RESISTANCE IN THREE BARLEY VARIETIES IMMUNE TO RACE 2

Abstract

The inheritance of smut resistance in two introductions of Abyssinian origin, Abyssinian (C.I. 668) and an unnamed variety C.I. 5798, as well as a variety of unknown origin, Kitchin (C.I. 1296), was the subject of study.From the results it was concluded that resistance in each variety is governed by a single dominant gene and that this one gene is common to all three varieties. Moreover, the varieties Steudelli (C.I. 2266) and Jet (C.I. 967), which were shown from a previous study to possess one and two dominant genes for resistance respectively, were found to possess the same gene as the three resistant stocks under study.
