【摘要】 对国内20余份骨干自交系进行耐旱性鉴定,测定其ASI、单穗平均产量、出籽率等指标,对筛选出的6个自交系进一步鉴定分析其抗旱指数、RI(修)。结果表明:Qi319、Ye107、F178耐旱性好,且自身产量较高,可作为耐旱种质资源加以利用。更多还原

【Abstract】 To domestic20mainstay’s maize inbred lines were c a rried on the appraisal of drought-enduring quality,ascertain by measuring such ASI,single spike equally yield,come out the targets such as seed rate and so on,selecting out in it6maize inbred lines and identify to analyze such and dro ught resistance index,RI(mending).Result showed:Qi319,Ye107,F178-drought-enduring quality are good,and oneself yield is taller,may utilize a s drought-enduring kind of character resources.更多还原
