杂交

The hybridization was conducted with brown cotton line Zong 128 as female parent, white cotton varieties FB20, Kuzhe T94-4 and Liao 96-23-30 as male parents. The genetic separations of the color of long fiber and linter in parents, F1 and F2 were analyzed.

方法］以棕色棉品系棕128为母本，白色棉品种FB20、库车T94-4、辽96-23-30为父本进行杂交，对亲本、F1、F2长纤维和短绒色泽的遗传分离进行了分析。

In this paper, we studied the effects of exogenous hormone and low temperature pretreatments on anther callus induction of oilflax (Linum usitatissimum L.).

本文以胡麻杂交组合1S×95005的F1为材料，研究了激素和低温预处理对花药愈伤组织诱导的影响。

In order to further study, with a new method of preparation of DNA fibers which has conquered the disadvantage of the way of squashing in liquefacient nitrogen,high-quality fibers were been gotten from maize which has large genome and contains numerous types of highly repeat DNA elements.

为了进一步分析，对现有的提核方法进行了改进，采用了新的方法制备DNA纤维，克服了液氮研磨法的不足，并在基因组比较大，重复序列较多的玉米上获得成功，同时用伸展DNA纤维的荧光原位杂交技术测定了端粒DNA在玉米染色体上的拷贝数。

Although there are many factors which influenced the transformation of Liriodendron hybrids, the use of acetosyringone in pre-culture time and co-culture time, the concentration of Agrobacteriun tumefaciens and the length of imbruing time were mainly employed to be analyzed in this research.

对于影响转化效果的众多影响因素，本研究主要讨论了乙酰丁香酮、菌液浓度、侵染时间对杂交鹅掌楸转化结果的影响。

So,the genetic distance could be used for the choice ofparents and for the heterosis prediction in cross breeding of Liriodendron.

因此，花粉品质、杂交亲和力和一般配合力应作为亲本选配的重要依据；基于RAPD标记的亲本间遗传距离与子代1年生苗高和地径生长量均表现为二次曲线相关，复相关系数分别为0.8235和0.5090，达极显著(H，P＜0.01)和显著(GLD，P＜0.05)程度，说明利用亲本间遗传距离进行鹅掌楸亲本选配和杂种优势预测是可行的。

Because it is not clear for the genetic background of all litchi's germplasm resources we have owned.

而荔枝杂交育种一直都没有采用，因为对现有荔枝种质的遗传背景不清楚。

Another theory is that the standard longhair dachshund was developed by breeding smooth dachshunds with various land and water spaniels.

另一个说法是，标准的长毛腊肠是短毛腊肠和不同的陆地和水猎犬杂交而成。

At the bookish assembly hosted by Secretary General Huang Chin-ying on January 3, Mr. Chang Pei-chen presented the first report on the Secrets of the 17-year Cicada written by Japanese Jin Yoshimura, a specialist of eco-mathematical model and biological evolution. The book was adapted from Yoshimura』s paper published in American Scientist in 1996, exploring the causes of evolution of magicicadas. Based on the duration of dormancy, magicicadas fall into two groups: the 13-year and 17-year periodical cicadas. Based on the principle of the survival of the fittest, as the lowest common multiple was larger, there were fewer groups proliferating at the same time to prevent damage of their ecological regularity as a result of hybridization.

1月3日读书会在黄晋英秘书长主持下，第一篇由张培臣先生报告《17年蝉之谜》，作者为日本人吉村仁，专攻生态数学模型与生物演化理论，本书改写自吉村仁於1996发表於《美国自然学家》期刊的论文，探讨质数蝉的演化缘由；依若虫期蛰伏於土壤中年份的不同，质数蝉大致可分为13年及17年两类，在天择情形下，因为最小公倍数比较大，同一时间的繁殖群相对比较少，可避免杂交而破坏其生态规律。
