Abstract

The invention provides a breeding method of a vineless Cucurbita moschata Duch and an application thereof, and belongs to the technical field of crop breeding and plant protection. The method comprises the following steps: 1, hybridizing a vineless pumpkin homozygous material A and a long type Chinese pumpkin homozygous material B as parents, so as to obtain F1; 2, using a parent B as the recurrent parent to continuously backcross with the F1 for n times, and continuously optimizing to obtain BCn, continuously backcrossing the BCn for m generations, continuously optimizing to obtain homozygous backcross line material BCnFm+1; 3, hybridizing the BCnFm+1 with the long type Chinese pumpkin homozygous material C to obtain the vineless Cucurbita moschata Duch. The technical problem that Cucurbita moschata Duch is not beneficial to close planting in the prior art is solved. The vineless Cucurbita moschata Duch is early-maturing, in long rod shape, good in taste, beneficial to close planting and high in the yield. According to the difference of the ecological conditions in the north and south regions, the remote continuous optimization is carried out, the regional adaptability is high, and considerable economic benefits can be brought to enterprises and farmers.

Description

technical field [0001] The invention relates to the technical fields of crop breeding and plant protection, in particular to a breeding method and application of a type of pumpkin without vine honey. Background technique [0002] Pumpkin is an annual crop of Cucurbitaceae Cucurbita.
