简介：到米饭异种的分子的水平上的变化的特征在空间环境导致了的进一步的学习，我们在四米饭异种(二high-tillering和二low-tillering)的叶子和种子分析了蛋白质在8(th)并且9(th)在一架15天的空间班机以后的代，并且与他们由two-dimentionalpolyacrylamide的扎根的控制相比，凝胶电泳和颠倒分阶段执行液体层析(RPLC)。另外，变异的种子的白朊，血球素，谷醇溶蛋白，谷蛋白，和直链淀粉被RPLC和紫外线spectrometry分析。结果证明在山峰的叶子的低丰富的蛋白质是到ering舞台为止更可能的与他们的相应控制相比被导致。当时，揭示的变异的种子的白朊，血球素，和谷醇溶蛋白变化稳定地与他们在不同异种的变化的控制，和特征相比被继承在8(th)并且9(th)代，建议他们能被用作简历标记到异种由空间飞行导致了的身份。而且，二蛋白质(SSP9111和SSP6302)被发现在不同异种与高紧张(双重的变化)被表示，它两个都根据集体spectrometry并且数据库寻找与相片系统被相关。

简介：到精选精英germplasms，从装饰用的梨树米饭栽培变种Wuyujing3导出的112异种被评估。象圆锥花序那样的收益部件每平方米数，谷物数字每圆锥花序，和谷物，重量被测量。象白垩的谷物(PCG)的百分比那样的优秀特点，稻谷收益(BRY)，milled米饭收益(MRY)，milling(DM)的度，直链淀粉内容(交流)，蛋白质内容(PC)，和在特点之中的关系是inverstigated。结果证明谷物产量每在谷物收益变化为94.64%贡献的平方米与6.4t/hm2的一个平均数和谷物的数字从2.15～12.49t/hm2。为优秀特点，所有米饭异种有短尺寸(谷物长度≤5.5 ；公里)并且大胆形状(到宽度比率=1.10-2.00的谷物长度)。大多数米饭异种(87.5%)低于20%有PCG价值。有的MRY重视甚于50%的所有异种，低于20%的交流值，和低于10%的PC值。白垩的谷物的百分比否定地显著地与MRY被相关并且断然与DM相关。BRY和MRY否定地显著地与DM被相关。PC显著地并且断然与MRY被相关并且否定地与DM相关，当交流没这些优秀特点地有重要关联时。有25米饭异种，完成了象白垩的谷物的低百分比那样的江苏标准装饰用的梨树米饭的主要要求，这被结束，低直链淀粉满意的、最佳的蛋白质内容，并且它能被用作精英germplasms。因此，识别的异种可以在米饭质量的改进导致重要进步。
