Breeding method for white-type strong female hybrid balsam pears

Abstract

The invention discloses a breeding method for white-type strong female hybrid balsam pears. The breeding method comprises the following steps: selecting a strong female line Q03, and selecting a conventional selfing line C170 and white-type strong female hybrid balsam pear Sichuan balsam pear 77. The invention aims to provide the breeding method for the white-type strong female hybrid balsam pears which are precocious, high in quality and high in yield, and facilitate industrial production. The white-type strong female line Q03 obtained by the technology has strong female genetic stability, precocious fruit, high yield, excellent traits and high resistance; the hybrid combination prepared by utilizing the strong female line Q03 and the conventional selfing line C170 has obvious advantages, the maturity is 3 to 10 days in advance, the yield is increased by over 30 percent compared with the conventional varieties, the commodity of the fruit is close to that of the conventional varieties, and the consumption habit of the area in which people like eating white balsam pears is satisfied; seeds are produced by hybridizing the strong female line Q03, so that the planting cost is low, the processes of binding bud and pollinating artificially in conventional hybrid seed production are reduced, moreover, the seed production yield is high, the production cost is reduced, and the industrial development of balsam pears is facilitated.

Description

Technical field [0001] The invention relates to the technical field of utilization of biological heterosis, in particular to a breeding method for white strong female hybrid bitter gourd. Background technique [0002] Momordica charantia is an annual climbing herb in the genus Momordica of the Cucurbitaceae family. It is cultivated all over my country, among which Guangdong, Guangxi, Hainan, Fujian, Taiwan, Hunan and Sichuan are more common. Its unique flavor, rich nutrition, high nutritional value and medical care value are deeply loved by consumers. As a high-end vegetable, bitter gourd has a high added value. With people's re-recognition of the nutritional value and many therapeutic effects of bitter gourd, the production of bitter gourd in my country has developed rapidly, and the cultivation area has expanded year by year. In terms of the cultivation system, with the increase in market demand for bitter gourd and the requirement of an annual balanced supply, as well as the...

AI Technical Summary

Problems solved by technology

Conventional hybrid varieties use conventional lines to hybridize with conventional lines, and have certain heterosis. Their high yield depends on sophisticated cultivation techniques and a long harvest period. The yield and output value vary greatly, and the cost of seed production and planting is high. For example, Taiwan Bi Xiu balsam pear and Yuehua balsam pear are mainly obtained by grafting technology to prolong the harvest period to obtain high yield
