It is primarily intended for use by breeders to introduce these characteristics into their breeding programmes. Selection of this line focussed on biotic stress resistance. This line is resistant to Russian wheat aphid biotype RWASA 1, stripe rust pathotype 6E22A+ as well as three virulent races of the Ug99 stem rust lineage found in South Africa namely TTKSF, TTKSP and PTKST. Agronomic traits and performance were not selection criteria, however this line does not contain any obvious negative agronomic traits except for the absence of alunimium tolerance. It has a good to excellent general appearance grown under supplementary and full irrigation in field conditions in South Africa. Under full irrigation a yield of 12 850 kg/ha was obtained with good test weight of 79.1 kg/hl . Bread making quality characteristics are acceptable and the line contains the high molecular weight glutenins 2*, 17+18 and 2+12 therefor, breeders should be able to include this line in their breeding programmes without introducing negative quality traits.
