Method for breeding premature cylinder-shaped luffa

Abstract

The present invention relates to a breeding method of early cylindrical towel gourd and belongs to the technical field of plant breeding and seed selecting. The invention uses the high generation selfing line of endemic species ''short cylinder'' towel gourd in Suzhou city of Jiangsu province as female parent, and uses the high generation selfing line of endemic species ''Changsha meat'' towel gourd in Changsha city of Hunan province as male parent for hybridizing to obtain first filial generation of common towel gourd, namely the ''Jiangsu cylindrical towel gourd No.1''. The ''Jiangsu cylindrical towel gourd No.1'' belongs to the first filial generation of common towel gourd and has the advantages of excellent earliness, strong capability for continuously generating towel gourd, strong low temperature resistance, representing high virus disease resistance and downy mildew resistance in the field for a plurality of years, cylindrical shape of commodity product fruit, well-shaped towel gourd, smooth towel gourd flesh quality, delicate fragrance, slight sweet mouthfeel, easy obtaining of high and stable production volume, excellent commodity property, excellent quality, and suitability for growing outdoor or with protection in the area where the people like to eat the ''Changsha meat'' towel gourd.

Description

1. Technical field [0001] The invention relates to a breeding method of early-maturing cylindrical loofahs, belongs to the technical field of plant breeding and selection, and is specially used for breeding the first-generation hybrids of early-maturing cylindrical common loofahs. 2. Technical background [0002] Cucurbitaceae (Cucurbitaceae) Luffa Mill. Plants, there are 8 species in the world, naturally distributed in tropical regions, and there are two cultivated species distributed in my country, namely common loofah [Luffa cylindrica (Linn.) Roem.] and Ribbed loofah [Luffa acutangula (Linn.) Roxb.] is an annual climbing herb with chromosome number 2n=2x=26. The present invention relates to common loofah. [0003] Loofah is cultivated in the north and south of my country and is one of the main melon vegetables in China. Ribbed loofahs are mainly distributed in Guangdong, Guangxi, Hainan and other regions, while ordinary loofahs are mainly used in other areas. In recent ...

Problems solved by technology

[0007] The present invention aims at the high nodes of the first female flower existing in the production and breeding of "Changsha meat" loofah type common loofah in the prior art; / 667m 2 ), the maturity is late; the rate of female flowers within 30 nodes is low, the middle part of melon strips is easy to form "waist waist", the flower pedicle is easy to over-swell, the ability of continuous fruiting is weak, and the yield is low and unstable; it is not resistant to low temperature, so it is not suitable Cultivation in protected areas in winter and spring or delayed cultivation in autumn; in the field, there are a series of problems such as resistance to viral diseases and downy mildew, and a breeding method for early-maturing cylindrical loofah is provided, which has good early maturity and strong continuous fruiting ability. , strong low temperature resistance, resistance to viral diseases and downy mildew in the field, the commercial fruit is cylindrical, without "wap waist" and the melon pedicle is not obvious, the melon strips are well-proportioned, the meat is delicate, fragrant, the taste is slightly sweet, and it is easy to eat. Obtaining high and stable yield, good commerciality, and good quality early-maturing cylindrical common loofah first-generation hybrids, suitable for open field or protected cultivation in areas that like to eat "Changsha meat" loofah
