导入外源总DNA获得优质高蛋白和双高大豆新品系

本文报道了利用大豆自花受粉后形成的花粉管通道，将外源野生大豆总ＤＮＡ直接导入受体栽培大品种中，其中一组合（Ｄ８７０１）获得的导入后代Ｄ８９－９８２，蛋白南含量比受体提高了近２个百分点，球蛋白总量提高近１０个百分点，并使其与大豆加工品质密切相关的１１Ｓ球蛋白组分所占比例超过了７０％该品系经品比和异地鉴定，产量比标准品种提高１１％，于１９９５年进入省区域试验；另一组合（Ｄ８７０５）的导入后代Ｄ９０－１

NEW SOYBEAN STRAINS OF HIGH PROTEIN AND DOUBLE HIGH CONTENT ABTAINED FROM INTRODUCTION OF EXOGENOUS TOTAL DNA

This paper repotrs that the wild soybean exogenous total DNA was introduced into cultivated soybean through pollen tube channel. The receptor progeny(D89-982) was abtained ftom the combination D8701.Ii's content of protein increased about 2 percent morethan the recipient and it's globin increased about 10 percent. The proportion of 11S globinwhich was most in rebation with the processing quality of soybean was higher than 70%.The yield of this strain was 11% higher than the standard variety by varietal coparison andregional test,and as an entry in provienctal district test of 1995. The average protein contentof the reseptor progeny(D90-1217) of another combination increased 9 percent more thanrecipient. The content of protein was 48.4%,the fat was 18. 34%,the total content of protein and fat was higher than 66.7%.
