目前测定农作物杂种优势的主要方法,需时长,工作量大。据国内外报导,酯酶同功酶是生物体内的一个天然指标,在一定程度上能反映出生物体内复杂的生化反应与外部性状的某些联系。我们测定了水稻威优6号、南优3号、南优2号、南优6号、汕优3号珍汕_(97)A×78-868、珍汕_(97)A×78-527-2、菲改A×78-824等8个杂交种及其16个亲本的籽粒酯酶同功酶,目的在找出酯酶同功酶谱与杂种优势的关系,以作为预测杂种优势的生化指标。
At present, the main method for determining the heterosis of crops needs long time and heavy workload. According to reports at home and abroad, esterase isoenzyme is a natural indicator of the organism, to some extent, can reflect some of the complex biochemical reactions in vivo with external traits. We measured the grain yield and grain yield of rice Weyou 6, Nanyou 3, Nanyou 2, Nanyou 6 and Shanyou 3 Zhenshan_ (97) A × 78-868, Zhenshan_ (97) A × 78- 527-2, the Philippine to change A × 78-824 and other 8 hybrids and their 16 parents of esterase isozymes, the purpose of finding esterase zymogram and heterosis relationship as a predictor of heterosis Biochemical indicators.
