Abstract
Walnut is an important cultivated tree, with high economic value and wide distribution across China.
Germplasm resources are the basis of cultivar breeding.
In order to scientifically take advantage of the rich germplasm resources in our country, we carried out a field investigation on the existing cultivated walnut resources.
We described the distribution of one of these important resources, Wu-ren walnut, in detail.
According to the desired target traits optimal selection values (high quality, high yield, thin shell and high kernel crack-out rate), we selected
6 excellent individuals.
These selections had a kernel crack-out rate of more than 45%. The main cultivated characters and economic characters of these 6 excellent individuals, the Baishui walnut, Hongrang walnut, Spiciform walnut were observed, measured and described and resource was evaluated.
This information will not only provide a theoretical basis for the protection of special germplasm resources of walnut and scientific development in our country, but also offer references and resources support for the breeding of new cultivars.
