Abstract

The invention discloses a production method of an environment-friendly economic cotton hybrid. As the production method adopts a special parent, the hybrid can be subjected to forge identification indoors during a main leaf period, so that the rapidness and the accuracy of the identification are improved, the purity of seeds is guaranteed, the stability of a seed market is ensured, the seed quality is guaranteed, and the phenomenon of forging and faking is effectively attacked. The production method can greatly reduce acid content during a process of removing woolen by sulfuric acid before sowing, reduce the damage to the seeds by the acid, guarantee the integrity of the seeds and protect environment, is beneficial to the growth of the seeds, is simple and practical, can be used for identifying the purity of the hybrid well for multiple times, avoids the phenomenon of forging and faking well, and protects the benefits of cotton planters.

Description

technical field [0001] The invention belongs to the field of cotton planting, in particular to a method for producing environmentally friendly and economical cotton hybrid varieties. Background technique [0002] High-yielding fine varieties are the basis for increasing crop yields. Each large-scale increase in crop yield is the result of large-scale promotion of superior replacement varieties. Breeding superior replacement varieties has always been the research direction of major agricultural countries in the world. The promotion of hybrid cotton is a good example. . However, insufficient attention has been paid to the problems in the promotion of fine varieties, which often leads to the growers mistakenly underestimating the yield-increasing potential of fine varieties, which delays the promotion of fine varieties, or even stops them from moving forward. For hybrids, the purity of hybrids in production and the potential for increasing production correspond to each other. ...
