Abstract:
The wheat-Aegilops ventricosa substitution line Moisson 6Mv/6B (highly resistant to stripe rust) was crossed with Sichuan wheat varieties mianyang 26, mianyang 93-124 and SW3243 (highly susceptible to stripe rust), respectively. Their F1 hybrids were further backcrossed as male and female to corresponding wheat varieties. The seed-setting rate, 6Mv chromosome confirmation, and resistance to stripe rust of the subsequent F1, F2 and BC1 plants were investigated for studying the transmission of chromosome 6Mv of Ae. ventricosa with different genetic backgrounds of Sichuan wheat varieties and analyzing the compensatory ability of 6Mv to 6B. The average seed-setting rate of the backcross via 6Mv as female donor was 83.10%, with the highest of 95.51%. However, the average seed-setting rate of the backcross via 6Mv as male donor was 48.61%, with the lowest of 28.47%. These results suggested that chromosome 6Mv had the negative effects on pollen related fertilization. Furthermore, the seed-setting rate was associated with the wheat genotypes. In the all analyzed populations involved in mianyang 26, mianyang 93-124, and SW3243, the transmission frequencies of chromosome 6Mv through male was not significantly different from those through female. However, the transmission frequencies of chromosome 6Mv were significantly correlated with Sichuan wheat genotypes. Additionally, the background of different wheat varieties was also correlated with the transmission frequency of 6Mv in monosomic substitution plants by selfing. The results from this study would provide a theoretical basis for the use of the wheat-Aegilops ventricosa 6Mv/6B substitution line in wheat breeding. Fig 1, Tab 4, Ref 15
