Abstract: In order to screen out disease-resistant materials to clubroot and provide excellent
germplasm resources for the subsequent breeding of new cauliflower cultivars with resistance to
clubroot, 35 inbred lines and 9 hybrids were inoculated indoors to identify their resistance to clubroot
by injured root irrigating inoculation. Two resistant materials of C17 and C32 and 10 medium resistant
materials were screened out, including 8 inbred lines of C2, C3, C4, C7, C13, C14, C19, C28 and
2 hybrids of C36 and C41. The two resistant materials were all early maturing inbred lines, and no
resistant materials were found in medium and late maturing inbred lines. |
