Problems solved by technology

[0007] Aiming at the current situation that there is no new film-free cotton variety breeding method in the prior art, the present invention aims to provide a new film-free cotton variety HZ-148 breeding method, which overcomes the single disadvantage of the current film-free cotton variety , the breeding method and means have been improved, and the breeding efficiency has been improved. By adopting a new variety HZ-148 breeding method of filmless cotton provided by the present invention, the new filmless cotton variety bred can be quickly grown under the condition of no film covering. Germinate seedlings, the emergence rate and seedling rate are not significantly different from those of cotton with film, which has great economic value in the field of cotton variety breeding technology

Embodiment 1

[0023] The present invention provides a kind of new kind HZ-148 breeding method of filmless cotton, and concrete breeding method step is as follows:

[0024] (1) Selection of cotton parents: the female parent Lumianyan 30 was selected, and the male parent Xinluzhong 37 was selected.

[0025] (2) Breeding of the first generation: the female parent of Lumianyan 30 and the male parent of Xinluzhong 37 were crossed to obtain F1 single plants.

[0026] (3) Breeding of the second generation: Select the excellent F1 generation single plants obtained in the above steps, select the drought-resistant and yellow-resistant upland cotton single plants suitable for the natural conditions of saline-alkali land, and then choose to plant them in southern cities in summer to obtain F2 generation single plants. strain.

[0027] (4) Breeding of the third generation: Select the excellent individual plants of the F2 generation obtained in the above steps, select a dry-resistant, yellow-resistant, ...

Abstract

The invention provides a breeding method for the novel variety HZ-148 of mulch-free cotton. The breeding method overcomes the shortcoming of a single variety of the mulch-free cotton in the prior art,improves breeding process and means and enhances breeding efficiency. With the breeding method for the novel variety HZ-148 of the mulch-free cotton, the bred novel variety HZ-148 of the mulch-free cotton can quickly germinate and sprout under the condition of no covering with a mulch film; the novel variety HZ-148 has no disease in a study plot, and does not receive attacks; the novel variety HZ-148 of the mulch-free cotton has unginned cotton yield of non-membrane cotton HZ-148 seed cotton is 335.6 kg / mu and an textile consistency index of 143, which is much higher than the textile consistency index of 125 of Xinluzhong No. 54; and the breeding method has great economic value in the field of cotton variety breeding technology.

Description

field of invention [0001] The invention relates to the technical field of cotton breeding, in particular, the invention specifically relates to the technical field of breeding of a new cotton variety. Background technique [0002] Cotton is an important economic crop in China, and my country is one of the major cotton-producing countries in the world. my country has widely promoted the use of plastic film mulching technology in cotton planting, which has greatly increased cotton production, bringing huge benefits to agricultural production and farmers' income. Covering with plastic film can increase temperature and moisture, suppress weeds, prevent insects and diseases, and retain water and fertilizer. The use of plastic film can increase crop yield by 20%-30%. With the continuous increase in the use of plastic film and the low recovery rate of residual plastic film, the amount of residual plastic film in the soil has gradually increased, the soil structure has been severel...
