Breeding method of new variety of short-branch low-phenol cotton suitable for mechanical picking

Abstract

The invention discloses a breeding method of a new variety of short-branch low-phenol cotton suitable for mechanical picking. The breeding method comprises the following steps: breeding a female parent-Huai 86 series and a male parent-Huai 203-5 series, and hybridizing by taking the Huai 86 series as the female parent and the Huai 203-5 series as the male parent to obtain the new variety of short-branch low-phenol cotton suitable for mechanical picking. The variety is early-maturing low-phenol cotton, the cotton is barrel-shaped and has short branches, and tomenta are formed on the stems of the cotton; the leaves are relatively large, the boll-setting property is relatively good, bolls are oval, the bolls are smoothly opened, and the agronomic trait is stable; the yield is relatively high and 57,000 bolls are produced in each mu (1 mu is 1 / 6 of acre); the bolls are intensively opened, the cotton is suitable for mechanical picking, and part of labor cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of plant breeding, and in particular relates to a method for breeding a new variety of cotton with short fruiting branches and low phenol, which is suitable for machine harvesting. Background technique [0002] In recent years, due to the increase of young and middle-aged migrant workers in rural areas, there is a serious shortage of rural labor force, and labor prices have risen sharply. Conventional hybrid cotton planting requires intensive cultivation, a low degree of mechanization, and a large amount of labor. The cost of cotton planting is getting higher and higher. The short-season cotton varieties introduced from the Yellow River Basin have poor ecological adaptability, and their yield and quality are not as good as those of local hybrid cotton. Cotton farmers urgently need a new cotton variety that is suitable for light simplification, mechanization, extensive cultivation and management, and can save...
