导入外源总DNA获得优质高蛋白和双高大豆新品系

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

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豆品种中，其中一组合（Ｄ８７０１）获得的导入后代Ｄ８９－９８２，蛋白质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Ｄ９０－１２１７，平均蛋白质含量比受体提高９个百分点，达４８．４７％，脂肪含量达１８．３４％，蛋白质含量十脂肪含量达到了６６．７％以上。

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%.
