THE RESEARCH OF MAJOR GENES AND THE EXPLOITATION OF GENETIC RESOURCES OF LIVESTOCK AND POULTRY
主基因研究与畜禽遗传资源开发

The major gene means a single gene or locus, which has great effect on quantitative trait. It is of great significance to the fixation of the beneficiad genotype, marker assisted selection, marker assisted introgression , the transgenic technology applied to quantitative trait and a big increase in economic benefit.The conception, present condition of major genes research on livestock and poultry were expounded in this paper.It is proposed that the exploitation of genetic resources of livestock and poultry aims essentially at finding and using major genes of special characters. How to exploit and use the major genes of livestock and poultry has been approached.
