Selection of Superior Strains of Walnut Resources in Northeastern Chengdu Plain

In order to further tap the local walnut germplasm resources, 100 excellent walnut germplasms in Deyang were screened and compared with ‘Liaohe No. 1’ and ‘Xiangling’ in terms of flowering and fruiting, nut traits and quality, stress resistance and so on. The results showed that (1) the selected walnut germplasms were ‘Jingke 1’ and ‘Jingke 2’, respectively. (2) Both ‘Jingke 1’ and ‘Jingke 2’ had the characteristics of good appearance, thin shell, light color and good quality of kernels with the genetic superiority of their parents, and showed the characteristics of good quality, high yield and strong resistance to stress. (3) The stress resistance of ‘Jingke 1’ and ‘Jingke 2’ was better than that of ‘Liaohe 1’ and ‘Xiangling’.
