缺失SBTi-A_2大豆杂交后代品系籽粒化学成分分析

ANALYSIS OF CHEMICAL COMPOSITION OF SEEDS OF SOYBEAN LINES LACKING TRYPSIN INHIBITOR (SBTi A 2)

对一个杂交组合后代１０个稳定缺失胰蛋白酶抑制剂（ＳＢＴｉ－Ａ２）品系及其亲本籽粒化学成分组成进行的分析比较表明，大豆籽粒中缺失ＳＢＴｉ－Ａ２对其蛋白质含量及天门冬氨酸、甘氨酸和丙氨酸含量有一定影响，表现为缺失ＳＢＴｉ－Ａ２品系显著低于高亲和双亲平均值；

Ten soybean lines lacking trypsin inhibitor, SBTi A 2,from one cross and their parent were deterimined for percetages of protein, amino acids, oil and fatty acids. It was shown that the percents of protein, glycine, alanine and aspartic acids were influenced by the lack of SBTi A 2, and were lower in the lines without SBTi A 2 than their higher parent and mid parent values. The lack of SBTi A 2 had no sigificant effect on the rest amino acids, oil and fatty acids.
