摘要:
为培育生理成熟后籽粒脱水快的玉米品种，解决玉米收获期含水量过高的问题，以德美亚♂（脱水快）×边自30（脱水慢）组配的100个重组自交系群体为材料，对生理成熟后籽粒自然脱水速率进行方差分析和遗传力估计，比较重组自交系生理成熟后籽粒自然脱水速率的差异。结果表明：家系间籽粒自然脱水速率差异达到极显著水平，且籽粒自然脱水速率表现较高的遗传能力，广义遗传力为76.93。同时对籽粒脱水速率进行了正态分布检测，检测结果符合正态分布。
Abstract:
In order to breed maize variety of quick dehydration after physiological maturity,to solve the problem of exorbitant moisture content of maize grain during harvest,taking 100 recombinant inbred lines from Demei ya(quick dehydration)×Bianzi 30(dehydration slow)group as materials,variance analysis and heritability estimates of grain natural dehydration rate after physiological maturity were studied,differences of dehydration rate of recombinant inbred lines were compared.The results showed that the difference of grain dehydration rate among families was significant,and grain dehydration rate had higher genetic ability,the broad sense heritability was 76.93.At the same time grain dehydration rate was tested by normal distribution,and the results was according with normal distribution.
