Abstract

The invention relates to an agronomic crop hybrid vigor utilizing method, wherein a transgenic pest-resistant sterile line is used as female parent, the conventional transgenic pest-resistant cotton is used as male parent for formulating hybridized combination, the pollination is completed through artificial breading of honey bees and miscellaneous insects existed in the nature and the first-filial generation seeds are produced. The invention overcomes the drawbacks of time and labor consuming, high working strength, comprehensive management for production of hybrid seeds and high cost of seeds production existed in the artificial pollination emasculation hybrid method for seed making, and can further improve the pureness of the hybrid.

Description

Technical field:

[0001] The invention belongs to a method for utilizing crop heterosis, in particular to a method for preparing cotton hybrids by using insect pollination. Background technique:

[0002] Cotton is the most important economic crop in the world. Like corn, rice and other crops, cotton also has obvious heterosis. Cotton hybrids have become more and more important in cotton production in recent years, and have become one of the main ways to increase cotton yield and improve cotton fiber quality. At present, the production method of cotton hybrid seeds is mainly artificial tasseling and pollination hybrid seed production. More than 90% of the hybrid seeds planted in cotton production are produced in this way. The artificial emasculation and pollination hybrid seed production method is the most relevant technical method in this patent. The following is a brief introduction to it from the three aspects of its purpose, steps and effects.

[0003] The artificial tas...
