中文摘要：

灰煤杆长度，圆锥花序长度，小穗状花小穗每圆锥花序和圆锥花序使突出离子被包括从 indica 和装饰用的梨树 Milyang 23/Jileng 的十字导出的 200 根线使用 F2:3 人口评估北京(自然正常生长环境)的 1 不到五不同环境， Kunming (自然冷环境)，中国(冷水灌溉)和朝鲜(自然正常生长环境和冷水灌溉)的 Chuncheon 的 Gongzhuling ，和这些特点的 QTL 被使用 SSR 标记分析。结果证明与这些农学的特点有关的 44 QTL 在五不同生长环境下面被检测，并且除了染色体 9，这些 QTL 位于 11 个染色体。为 qCL1a， qCL1b， qCL5a， qCL6b， qPL1a， qPL3a， qPL6b， qPL6c， qPL7b， qSP8b， qSP1c， qSP11a， qSP12，和 qPE1 的 QTL 在是环境影响的很少的超过二生长环境，和那些下面被检测了，是稳定的 QTL在他们之中， qCL1a， qCL1b， qPL1a， qSP1c，和 qPE1 向 24.2 解释了 55.2% ， 22.7 39.9% ， 12.5 27.7% ， 14.4 33.5% ，和 26.6 28.7% 观察 phynotypic 变化，分别地它是主要出现作为的主要基因过去优势。这些 QTL 在行动引起增加到灰煤杆长度，圆锥花序长度，小穗状花小穗每圆锥花序，和圆锥花序使突出在冷环境下面的离子，证明这些 QTL 与冷忍耐被相关。

英文摘要：

The culm length, panicle length, spikelets per panicle and panicle exsertion were evaluated by using F2：3 population including 200 lines derived from the cross of indica and japonica Milyang 23/Jileng 1 under five different environments of Beijing （natural normal growing environment）, Kunming （natural cold environment）, Gongzhuling of China （cold water irrigation） and Chuncheon of Korea （natural normal growing environment and cold water irrigation）, and QTLs of these traits were analyzed by using SSR markers. The results showed that 44 QTLs related to these agronomic traits were detected under five different growing environments, and these QTLs have been located on 11 chromosomes except chromosome 9. The QTLs for qCLla, qCL1b, qCL5a, qCL6b, qPLla, qPL3a, qPL6b, qPL6c, qPL7b, qSP8b, qSPlc, qSP11a, qSP12, and qPE1 have been detected under more than two growing environments, and those that were little affected by environments, were stable QTLs. Among them, qCLla, qCLlb, qPLla, qSPlc, and qPE1 explained 24.2-55.2%, 22.7-39.9%, 12.5-27.7%, 14.4-33.5%, and 26.6-28.7% of observed phynotypic variation, respectively, which were major genes mainly appearing as overdominance. These QTLs cause the increase in action to culm length, panicle length, spikelets per panicle, and panicle exsertion under cold environment, showing that these QTLs were correlated with cold tolerance.
