Thus, CMS lines are needed to improve insect pest resistance in hybrid rice.
因此，杂交稻抗虫性的提高有赖于不育系的改良。
Different cytoplasmic effect on out-crossing characters mainly show on exserted stigma of CMS lines.
不同细胞质对不育系异交习性的影响主要表现在柱头外露率的差异上。
Total nitrogen accumulation amount of CMS lines was distinctly higher than their homotypic lines (P<0.05), with more nitrogen distributed to stalk and grain in CMS lines.
CMS玉米氮素积累总量高于其同型可育系（P<0.05），成熟期氮素在茎秆和籽粒中分配较多；
Honglian (HL) type CMS lines (Indica) differed from wild abortive (WA) type CMS lines (Indica) not only in characteristic of abortive pollen but also in restoring and maintaining abilities.
籼稻红莲型(HL)不育系和野败(wa)型不育系除花粉败育的特征不同外，两者还具有不同的恢、保特性。
Number of nymphs on the hybrids Shanyou 63 and Xieyou 9308 was similar with that on TN1. The super-susceptibility in the hybrids originated from the susceptibility of its parent of the CMS lines.
在杂交稻汕优63和协优9308上的若虫数量与TN1上的相当，杂交稻的感虫性主要来源于其不育系亲本。
