红麻超高产型杂交组合的研究

本文从产量性状、抗病性和纤维品质等方面分析了 8个红麻杂优组合一、二代的优势表现。试验表明杂优组合的一、二代的优势是显著的。其中超高型杂优组合 H30 5 F2在比较试验中分别比 KB2、74— 3、红引 135分别增产 2 3.97%、33.47%、5 3.4%,达极显著水准。在全国红麻区试中 ,比对照红引 135平均增产 2 8.0 8%,较对照和其它所有参试新品种极显著的增产 ,表现出植株高大 ,皮较厚 ,有效株数多 ,生物产量和出麻率均高 ,抗病性强 ,纤维品质好 ,其前景非常广阔。红麻化学杀雄制种为红麻超高产型一、二代优势利用的应用和推广提供了快速、简便的制种方法 ,这说明红麻杂种优势的利用不仅在生产上大面积应用和推广成为可能 ,而且也是优化红麻种子结构和达到显著提高经济效益和社会效益的目的

Studies on the superior yielding hyStudies on the superior yielding hybrid combination fo kenaf

This paper dealts with the performance of yield,anthracnose resistance,and the fiber quality of F1,F2 of8kenaf hybrid combinations.The results showed that the vigor of F1,F2 of hybrid combination was obvious. The output of F2 of superior hybrid Kenaf H30 5 was2 3.97%,33.47%,5 3.4%respectively higher than that of KB2 ,74- 3and Hongyin135 in the comparing trial,and 2 8.0 8%more than that of Hongyin135 in national region trial,which performed best among all the tested varieties and hybrid. The outstanding characteristics of H30 5 were tall and large plants,much more effective plants, high bio- mass and fiber rate,strong disease resistance,good fiber quality.There was a great potential for utilization in production.
