Abstract:

Protein,oil and gossypol in cottonseed are the main components determining the value attributes of cottonseed. Their content and proportion are jointly affected by genetic background and environmental conditions. Factors such as enzymes and transcription factors involved in the biosynthesis of these three components are the primary determinants of their levels,while environmental conditions,including temperature,nutrients,light,and water,as well as cultivation practices also play important regulatory roles. Therefore,by breeding specialized varieties and optimizing cultivation conditions,diverse market demands can be aligned with agricultural production,thereby promoting the market-oriented utilization of cottonseed. This paper primarily analyzes the main controlling factors of protein,oil and gossypol content in cottonseed from a genetic perspective and discusses the external effects of environmental factors,aiming to provide references for cotton variety breeding and cultivation management.

Key words: cottonseed component, protein, oil, gossypol, genetic factor, environmental factor, cultivation technique
