5 results about "Cross breeding" patented technology

The invention provides a cucumber wilt resistance breeding method. The breeding method comprises the following steps: S1 selecting a breeding main parent and a resistant source parent; S2 performing cross breeding; S3 preparing a crude toxin extracting solution; S4 respectively performing anther induction culture on the cucumber breeding main parent and the resistant source parent; S5 determiningthe crude toxin screening concentration; S6 performing anther culture on a hybrid F1 generation; S7 transplanting flower culture seedlings after rooting; S8 performing wilt resistance identification and offspring screening. Hybrid breeding and a haploid breeding technology are combined to significantly improve the cucumber wilt resistance breeding efficiency and shorten the breeding period, and anewly developed cucumber wilt resistant line is good in resistance and further excellent in agronomic trait; while the yield is ensured, the application amount of pesticides and reduce environmental pollution can be reduced; the method is an effective way to rapidly breed new varieties resistant to cucumber wilt.
