| 摘 要： | 本文通过对黑龙江省38个玉米自交系生理成熟期及子粒自然脱水速率的研究,表明中晚熟材料生理成熟期在抽丝后50～60d,此时含水量在23%～35%;中早熟材料生理成熟期在抽丝后45～50d,此时含水量在28%～35%;供试自交系间子粒自然脱水速率存在显著差异,变幅为0.326%～1.371%,其中中晚熟组的吉846、吉16和中早熟组的龙抗11、杂C546、东91为脱水较快的玉米自交系,可作为快速脱水材料加以利用.

| Abstract: | Both physiological maturity stage and kernel dry-down rate of 38 corn inbred lines were analyzed in this paper.The results showed that the mid-late and mid-early inbred lines tested reached their physiological maturity stage at 50～60 and 45～50 days after silking ,and water content reached 23%～35% and 20%～35% respectively.In addition,the dry-down rate of the inbred lines tested were significantly different whose variation is 0.32%～1.371%.The mid-late lines JI846、JI16 and the mid-early lines Long-Kang11、Za-Xi 546、Dong 91 were moisture quick-loss inbred lines and could be used in maize breeding program. |
