美国农业研究局植物遗传学家J·PemGustafson指出，急需用遗传基因的多样性来改良谷物品种，特别是水稻和小麦品种。准确鉴定和利用遗传基因又是选育新品种的基础和前提。Gustafson与中国进修学者合作，基于人类与小麦、水稻，以及老鼠都具有15对DNA基因排列，决定探索用DNA指 J. PemGustafson, a plant geneticist at the Bureau of Agricultural Research, said that there is an urgent need to use genetic diversity to improve grain varieties, especially rice and wheat. Accurate identification and utilization of genetic genes is the basis and premise of breeding new varieties. Gustafson, working with Chinese fellows, has 15 pairs of DNA-based arrangements on human and wheat, rice, and mice and has decided to explore the use of DNA finger
