主基因研究与畜禽遗传资源开发

THE RESEARCH OF MAJOR GENES AND THE EXPLOITATION OF GENETIC RESOURCES OF LIVESTOCK AND POULTRY

论述了畜禽主基因的概念、利用价值及研究状况，指出我国畜禽遗传资源的开发，实质上就是要发掘利用特异性状的主基因，并就如何开发利用主基因进行了探讨。

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.
