Abstract: In order to select the resistant materials to fusarium wilt of chieh-qua, 20 resources of chiehqua (lines of self bred, separated and finally stable) were evaluated by root soaking method. The results showed that the average disease index of No.1 was the highest (86.34), No.13 was the lowest (35.65), and there was no significant difference among No.1, No.20, No.3 and No.9. In 20 materials, 6 materials (No.1, No.20, No.3, No.9, No.5 and No.11) were highly susceptible to fusarium wilt, 4 materials (No.19, No.4, No.2 and No.6) were susceptible to fusarium wilt, and 10 materials (No.15, No.7, No.10, No.16, No.8, No.12, No.18, No.17, No.14, No.13) showed moderate resistance, accounting for 50%. The disease of Qixing chieh-qua type was more serious, but Jiangxin chieh-qua type was better. Therefore, the possibility of obtaining high resistance level with Jiangxin chieh-qua type screening was higher. |
