Abstract:
Seven single-plant selections of wild emmer, with temperature-sensitive minor-effect genes for stripe rust resistance, were intercrossed in eight combinations. The resulting progenies were studied for a possible additive gene action. The transgressive segregation towards resistance in F2 observed in all the combinations indicates that additive gene action for resistance indeed occurs in wild emmer. The common occurrence of this phenomenon in random combinations suggests further that several minor-effect genes are involved. Following selection of the most resistant plants in F2, a marked shift towards resistance was noted in F3, which demonstrates a positive response to selection. In some instances, additive resistance selected for (in F2) at the high temperature-profile was expressed (in F3) also at the low temperature-profile. This kind of resistance, when utilized in breeding programmes, promises therefore to be effective over a range of temperatures. © 1984 Veenman B.V., Wageningen.
