How to select and breed cruciferous vegetables materials and varieties in rapeseed haploid guiding system

摘要

The present invention includes a step 1) of collecting, identifying and classifying cruciferous and vegetable resources and adjusting the seeding time of the guiding system to match the flowering period; Step 2) of moisturizing the cruciferous vegetables with the guidance system; Step 3) Cover self-pollination by self-pouring or self-pollination by peeling off shoots at bud period; Step 4) proceeding with system stability detection; Step 5) of crossing a stable lineage with a sterile system; Step 6) of selecting and breeding a good quality control by examining the infertility of the black crossed breed; Step 7) to pollinate the inoculated subspecies to the infertile system; Step 8) of investigating the induced growth of the new infertile system by hydration to the infertility line by the guidance system; And a step 9) of screening and breeding new combinations hybridized by in vitro crossing with the infertile system to provide selective breeding of cruciferous vegetable cultivars using a haploid guidance system.
