Abstract:

To develop excellent germplasm resources for drought-resistant breeding of wheat and to make better use of existing drought-resistant varieties, the breeding process of a new drought-resistant wheat variety ‘xinmai39’ was expounded, and the high productivity of this variety was analyzed by using the gray correlation degree. The results showed that the weighted correlation degree of ‘xinmai39’ was higher than that of the CK ‘luohan7’ in the three groups of two growing seasons, which was consistent with the statistical analysis results. The grey correlation degree analysis was conducted on the yield and three yield components of ‘xinmai39’ within the same site in the three groups of two growing seasons. All results showed that the contribution of thousand kernel weight > spike numbers per hectare, and the contribution of grain number per spike to grain yield was different. Therefore, ‘xinmai39’ is a new drought-resistant variety with high productivity, which can be extended and applied in arid and semi-arid regions, and it is also a new drought-resistant germplasm resource.
