查询词典 segregant

Fertile and sterile pools were set up by bulked segregant analysis based on the selection for the highly fertile and highly sterile plants of Shanyou 63 F_2 populaiton The AFLP analysis of the two pools indicated that 64 primer combinations amplified 3 477 stable and clear bands.

选择汕优63F_2的高可育株和高不育株分别建立 2个基因池，利用 AFLP标记技术对2 池间的多态性进行了研究。分析表明，64组引物在两池间全部扩增出了稳定、清晰的带纹，共计3 477条带。

80 Individuals of ATA-A F2 plants were used for RAPD molecular mapping of the monoecious gene by bulk segregant analysis. 840 random primers were chosen for polymerase chain reaction amplification between monoecious pool and andromonoecious pool, the results showed that: primer S128 was tightly linked to the monoecious character, and primer S493 was tightly linked to the andromonoecious character.

以甜瓜单性花系ATA-A系与两性花品种YJX-1的杂交F2代的80个单株为材料，利用群分法进行单性花基因有关RAPD分子标记研究，筛选分析了840个10bp随机引物的PCR扩增谱带，结果表明，随机引物S128在1180bp，S493在930bp处产生与性别相关的特异性条带，S128的特异条带与单性花性状相关，S493的特异条带与两性花性状相关。

The CMS line 9704A, the restorer 8001 and F, population of 9704AX8001 containing 120 individual plants were used for molecular mapping of the restorer gene by bulked segregant analysis. 515 decamer primers with arbitrary sequences were chosen for polymerase chain reaction amplification. It is found that the polymorphism between the parents could be detected by 43. 8% of the primer and one RAPD marker OPL09-76I was tightly linked to the restorer gene of the restorer 8001 with the overcross value of 4.17% and genetic distance of 4. 18cM. The marker was repeatable and easy to score.

以辣椒CHS系9704A、恢复系8001及其组合9704A×8001F_2群体120株植株为材料，利用群分法法进行恢复基因定位，通过515个随机引物的PCR扩增分析，发现43.8％的引物在双亲间表现出多态性，找到一个与辣椒CMS恢复系8001中的恢复基因紧密连锁的分子标记OPL09_(-763)，该标记与8001的恢复基因的交换值为4.17％，遗传距离为4.18cM。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.
