【摘要】 本文对黑龙江省1986～2010年间审定推广的275个大豆品种的子粒蛋白质、脂肪和蛋脂总量等品质性状指标进行了分析。结果表明,2006～2010年审定的大豆品种的不同品质性状最高值均高于1986～1990年的最高值,其中,大豆品种脂肪含量最高值显著提高,与品种推广年代间存在显著的线性回归关系,说明近年来大豆品质育种尤其是高油育种取得较大进展。育成蛋白质含量高于45.0%的大豆品种8个,脂肪含量在23.0%以上的品种9个,蛋脂总量在63.0%以上的品种23个。更多还原

【Abstract】 In this paper,we analyzed the change of protein content,oil content and total content of 275 released soybean varieties during 1986 to 2010 in Heilongjiang Province.The results showed that the maximum of different quality traits of soybean cultivars from 2006 to 2010 were higher than these from 1986 to 1990.The maximum of oil content of soybean cultivars increased obviously,and furthermore,the characteristic was significantly related to year of cultivar release.It proved that quality breeding of soybean has acquired the greater development in recent years,particularly the higher oil breeding.Protein content of 8 cultivars was beyond 45.0%,oil content of 9 cultivars was beyond 23.0%,and total content of protein and oil of 23 cultivars was beyond 63.0%.更多还原
