The result would be used in tobacco breeding.4 SRAP technology is used to study the genetic differences among different types of tobacco, including flue-cured tobacco, oriental tobacco, maryland tobacco, burley tobacco, and air/sun cured tobacco, five pairs of primer combinations which can amplify characteristic bands has been screened. Among the five combinations, two of them (SF25*SR2 and SF3*SR26) can distinguish air-cured tobacco including maryland tobacco and Burley tobacco from the other cultivated forms; SF20*SR14 can distinguish sun cured tobacco including oriental tobacco and sun-cured tobacco; SF16*SR14 can distinguish flue-cured tobacco and air-cured tobacco, and SF22*SR14 can distinguish DBJ599 with specisl aroma and the other flue-cured tobacco.5 8 varieties , which represent the different types of tobacco, are divided into 3 groups. I: G-28, II:DBJ599、MD40、By21, III: Basma、Sumsun、XNS、QCT. The cluster analysis result es consistant with experience evatuation.6 Anorthogonal design was used to optimize a ILP-PCR system with 5 factors (DNA, Mg2+, dNTP, primer and Taq polymerase) at 4 levels.The result showed the optimized ILP-PCR system for Nicotiana tabacum L. was: 2uL10×PCRbuffer, 20ng template DNA, Mg2+ 2.0mmol/L, dNTP 150umol/L, primer 0.3umol/L, Taq DNA polymerase 1 U in a total of 20uL reactionsolution.

研究结果可作为烤烟与香料烟类型间的杂种鉴定利用的实验与理论依据。4、利用SRAP标记技术，研究和分析了烤烟、晒烟、晾烟、白肋烟、香料烟等不同栽培类型间的基因型差异，初步筛选出了能够在分子水平上反映不同烟草类型差异的特征性标记带：晾烟MD40、Ky17、Burley21、TN90基因型共有的特征带有两对引物组合，分别为SF25*SR2和SF3*SR26；晒烟小牛舌、青梗、小花青和香料烟Sumsun、komotini Basma、Xanthi Basma共有的特征带引物组合为SF20*SR14；NC89、K326、G-28、大白筋和MD40、Ky17、Burley21、TN90共有的特征带引物组合为SF16*SR14，烤烟中大白筋599的特征带引物组合SF22*SR14.5、利用61对SRAP引物组合，研究了普通烟草不同类型间的亲缘关系，将普通烟草类型间8个不同供试材料划分为3类别。I：烤烟类型G-28II：白肋烟类型(MD40、By21、大白筋599III：香料烟类型(Basma、Sumsun、小牛舌、千层塔)。

However, crossing fertility between them was lower than that of mating in and in, and fertilized egg of reciprocal crossing can be incubated and produced F〓 without prezygotic isolation. Among all combinations of reciprocal crossing, crossing of wild male quail×female small-type domestic quail are proved to produce the best effect.

野生日本鸣鹑与家鹑群体之间的杂交能育性低于同种群交配水平，但可以实现正、反交，产生受精卵、孵化出杂种一代，不存在合子前生殖隔离；在所有正、反交组合中，以野雄鹑×小型雌家鹑的效果最好。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
