Abstract

The main purpose of this study is to figure out how to make cottonseeds contain more oil and better oil quality. We started from several aspects, such as genetic improvement, molecular technology, field management and environmental factors. The study found that if we make full use of the genetic differences of different cotton varieties, combined with traditional breeding, gene markers and genetic engineering technology, we can effectively increase the content of cottonseed oil and make the fatty acid composition of the oil more reasonable. The management method in the field is also critical. For example, how much water is irrigated, how much fertilizer is applied, and how dense the cotton is planted, all of which will affect the yield of cottonseed and the quality of oil. We also found that if some specific genes (such as GhSWEET42) are expressed more, the cottonseed can grow larger and contain more oil. This is very helpful for future genetic breeding. The interaction between the environment and genes will also affect the stability and genetic effect of oil. This study provides theoretical support and practical methods for the future breeding of high-oil cotton varieties and the realization of large-scale production.
