杂交

To determine the inheritance of resistance in Chuanmai 42, it was crossed and backcrossed with the susceptible Sichuan varieties of common wheat Mianyang 26 (MY26) and Mianyang 335 (MY335) for preparing the F2 and BC1 populations. A total of 208 and 337 F2 plants of Chuanmai 42×MY26,Chuanmai 42×MY335, and 171 and 216 BC1 plants of Chuanmai 42/MY26//MY26,Chuanmai 42/MY335//MY335, respectively, were used for resistance analyses.

为明确川麦42抗条锈性遗传基础，将川麦42分别与高感条锈小麦品种绵阳26、绵阳335杂交和回交，获得杂交F1、F2、BC1群体，其中，川麦42×绵阳26、川麦42×绵阳335 F2群体分别为208和337株，川麦42/绵阳26//绵阳26、川麦42/绵阳335//绵阳335 BC1群体分别为171和216株用于抗性遗传分析。

Six inbred lines of sweet corn with great genetic diversity were used as parents to make complete diallel crossing using Griffing method I . Some combinations were backcrossed and selfcrossed.

选用遗传差异较大的加强型甜玉米自交系6份做杂交亲本，按Griffing方法I遗传交配设计配制组合，并对部分杂交组合做自交和回交试验，研究甜玉米含糖量性状的遗传。

The wheat transformation frequency was between 0.33~0.66%, and cultivated time was only about 3~4 months.4 Through the hybridization of Anhui local wheat cultivated variety and the herbicide resistance variety which is including Bar gene by genetic engineering, the herbicide resistance F1 generation plant were obtained which was self-crossed or backcrossed with Anhui variety.

转化周期为3~4个月左右。4 杂交育种以含Bar基因的抗除草剂小麦基因遗传工程体为基因供体，与安徽品种进杂交，获得的F1后代均为抗性植株。

As the Kennel Club also registers crossbreeds, Crufts also hosts many competitions and displays for crossbreeds.

杂交犬种也可以在英国养犬俱乐部注册，因此Crufts也举办杂交犬的比赛和展示。

Results: This probe hybridized with DNA of W.bancrofti only, not with DNAs of B. malayi , some animal filariae and normal mosquitoes.

结果：该探针只与班氏丝虫感染蚊提取的DNA杂交，不与马来丝虫感染蚊提取的DNA、其他动物丝虫DNA以及正常蚊DNA杂交。
