Abstract

The invention discloses a method for producing seeds of a yellow-stem dwarf cucurbita moschata through distant hybridization, belonging to the field of a method for breeding new varieties of plants. Inbred lines of the bred dwarf cucurbita moschata are hybridized with bred yellow-stem vining cucurbita moschata to produce a hybrid F1, and the hybrid F1 is then inbred and purified to produce purebred inbred lines of the yellow-stem dwarf cucurbita moschata which is hybridized with a matched cucurbita maxima to produce a distant hybridization product variety. The method has the advantages that the total flavonoid content, practical value, yield, land utilization rate and economic benefits of the cucurbita moschata are all improved.

Description

technical field [0001] The invention belongs to the field of hybrid breeding methods for new plant varieties, in particular to a distant hybrid breeding method for pumpkins. Background technique [0002] Pumpkin is an annual crop of Cucurbitaceae Cucurbita. At present, there are many varieties cultivated at home and abroad, which can be divided into three categories: Chinese pumpkins, commonly known as pumpkins, American pumpkins, also known as zucchini, and Indian pumpkins, which are called winter squash. Among these three types, only American squash has dwarf species, and there are no dwarf species in Chinese squash and Indian squash before, and there is no report of yellow stem species in the three types of melons. Dwarf Chinese squash and yellow-stem Chinese squash are new varieties discovered and successfully bred by Mr. Wang Jiasheng for the first time in my country. The patent number is ZL92113528.9 Dwarf Chinese squash hybrid seed production method, ZL92113529.7 Dwa...
