高粱是甘肃省主要的禾谷类作物之一,特别是近年随着水资源的溃乏,降水减少,自然灾害的频繁发生,干旱严重的形势下,高粱以其适应性广,抗瘠抗旱性强,粮草兼用,产量高的优点,在粮食生产中起着重要的作用.“天杂9144”是我所于1996年以ZA(外引不育系)为母本,自育恢复系TH_(10).为父本测配育成的国内第一个高抗矮花叶病的高粱杂交种.该杂交种株高160cm左右,茎粗2.8cm,为长方中紧穗型,穗长30～40cm,单穗重108.5g,褐壳黄色,千粒重32.1g,籽粒角质率30%,生育期130～135天,蛋白质含量9.04%,单宁0.57%,淀粉含量74.5%,“天杂9144”的淀粉含量大大超过全国拟定酿造型品质标准,为优质酿造,饲料兼用高粱杂交种.1994年甘谷试验站栽培试验中,亩产达到700多kg,1996年通过天水市科委组织的技术鉴定,综合评价达到国内同类研究的领先水平.现将结果总结如下.
Sorghum is one of the major cereal crops in Gansu Province. Especially in recent years, sorghum has wide adaptability and strong barren drought resistance due to the shortage of water resources, the decrease of precipitation, frequent natural disasters and severe drought. , Forage and grass, the advantages of high yield, plays an important role in food production. “Tiaoshan 9144” is my in 1996 to ZA (male sterile line) as the female parent, self-recovery department TH_ (10 ) For the father measured and dubbed the first high resistant dwarf disease of sorghum hybrids in China.The hybrid plant height of about 160cm, stem diameter 2.8cm, rectangular and tight panicle type, spike length 30 ~ 40cm , Single panicle weight 108.5g, brown shell yellow, grain weight 32.1g, seed keratin 30%, growth period 130-135days, protein content 9.04%, tannin 0.57%, starch content 74.5%, “gossamer 9144” starch Content greatly exceeded the national brewing quality standards for high-quality brewing, feed and sorghum hybrid.In 1994 Gangu test station cultivation test, the mu yield reached more than 700 kg in 1996 by the Tianshui Science and Technology Commission organized a technical appraisal, a comprehensive evaluation Achieve the leading level of similar research in China now summarized the results below.
