- Plant type and rice quality of northern Japonica rice and their interrelations are studied based on the experiment of incomplete diallelled cross between 10 CMS lines and 10 restore lines. 利用10个不育系与10个恢复系不完全双列杂交试验,对北方杂交粳稻株型、米质及相互关系进行研究,结果如下:1。
- The yield of the crosses between three CMS lines and 1102C were higher 11.1% and 7.1% than cross 213A/1102C and 214A/1102C,inspectively. 用这三种不育系与1102C作杂交;其杂一代经济性状均优于213A/1102C和214A/1102C;产量分别比213A/1102C和214A/1102C增产11.;1%25和7
- The survival rate of hybrids was very significantly correlated with that of restorer lines, and significantly correlated with that of CMS lines. 杂交稻淹涝后生存率与恢复系呈极显著正相关,与不育系呈显著正相关。
- In BC1 progenies,CMS lines were produced. They were similar to ornamental kales in shape and color of leaves, and their anthers began to abort at the stage of two-nuclear pollen. 所得BC_1代为过渡性羽衣甘蓝胞质雄性不育系,其叶形叶色和父本羽衣甘蓝相似,花粉孢原细胞时期或单核期败育。
- The genotypes of the CMS lines are S(rf 1rf 1rf 2rf 2) and S(rf 1rf 1Rf 2rf 2), Whereas those of the fertile plants are S(Rf 1- Rf 2- ),S(Rf 1- rf 2rf 2), and S(rf 1rf 1Rf 2Rf 2). 不育株的基因型为S(rf1rf1rf2rf2)和S(rf1rf1Rf2rf2),可育株的基因型为S(Rf1-Rf2-)、S(Rf1-rf2rf2)和S(rf1rf1Rf2Rf2)。
- Both N transportation efficiency and N contribution rate of CMS lines were higher in contrast to the homotypic lines under nitrogen deficiency (P<0.05). 低氮水平下,CMS玉米的氮素转移率、贡献率和氮素利用率均显著高于其同型可育系(P<0.;05);
- 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;
