Semi-Okra leaf cotton hybrid, CLA 17 ZR4, which was made by super Okra leaf sterile line and Zheda strong restorer line, had a 13 % higher yield over CK.

测定发现，超鸡脚叶、鸡脚叶、中鸡脚叶、大鸡脚叶和正常叶5类杂种的生育期依次随叶面积系数增加而延长，中鸡脚叶杂种因具有适中的生育期和叶面积系数，产量和光合作用性状的综合表现最好。

Three full-sibling binary CMS lines, 11 back-cross binary CMS lines, 10 half-sibling binary CMS lines, 10 isozygoty CMS lines and five restorer lines were chosen to make 50 single hybrids and 120 modified single cross hybrids by the way of NC Ⅱ design. The plots of F1 were arranged in the field in a randomized complete block design with 2 replications and the combining ability of 7 characters were analyzed using random model.

利用3个全同胞型二元不育系、11个回交型二元不育系和10个半同胞型二元不育系及其10个亲本纯合不育系，分别与南恢04、明恢86、辐恢838、先恢207和密阳46等5个恢复系按照NCⅡ交配设计配制了50个单交种和120个改良单交种，按随机区组的随机模型分析方法，对二元不育系主要性状进行了配合力分析。

The results showed that the characters of F1 hybrids were extensively controlled by their nuclear genes; lint percentage lint index seed index and fiber length of F1 hybrids were significantly influenced by Harknessii cytoplasm on a greater extent and most of characters had no obvious interactions between cytoplasm and nuclear gene.

结果表明：杂种F1各经济性状广泛地受核基因控制；哈克尼西棉细胞质对F1的衣分、衣指、籽指及绒长有显著影响，且作用程度较高；多数性状不存在明显的核质互作效应。

As compared with reciprocal hybrids, lint percentage of F1 hybrids with Harknessii cytoplasm decreased by 4%~7% with a lower lint index and higher seed index, but their fiber length increased 1~2mm.

同核异质种相比较，哈克尼西棉细胞质F1衣指较低，籽指较高，衣分降低4~7个百分点；绒长增加1~2mm；纤维细度和断长也表现一定负效应。

To estimate the quantitative genetic parameters of nitrogen use efficiency, twenty maize single-cross hybrids with varying nitrogen use efficiency were tested at two locations in the North China Plain. At both locations, the hybrids were grown under high (HN, 225 kg/hm^2 N) and low N levels. And no N fertilization on the LN field have lasted two years.

为研究玉米品种氮利用效率相关性状的遗传参数，本试验选择20个具不同氮利用效率的单交种在华北平原的2个地点同期进行试验，氮肥处理设高氮（施氮，折合纯氮225 kg/hm^2）和低氮（不施氮，其地块经过连续2年耕种使氮素耗竭）2个水平。

The POSS-based hybrids were characterized by FTIR,~1H-NMR,~(29)Si-NMR and UV. The POSS content in the hybrids were determined using three kinds of different methods and could be effectively controlled by varying the POSS feed ratio.4. It was estimated that about 5~8 vinyl groups in POSS participated in the copolymerization reactions by the ~1H-NMR spectra.

分别采用FTIR、~1H-NMR、~(29)Si-NMR和UV等方法对五个系列POSS基高分子材料进行了表征，证实POSS已与共聚单体发生了聚合反应；并通过红外标准曲线和紫外标准曲线以及核磁积分面积对共聚物中POSS的含量进行了计算，发现可以通过投料比来控制共聚物的组成。
