育成品种

In this paper, major agronomic traits and grain quality traits affecting rice yield and grain quality were investigated in seven aromatic rice maintainer lines bred in Sichuan and one variety introduced from America. It was aimed at estimating the numbers of gene controlling aroma, the allelism of aroma genes, location of aroma gene on the chromosome, and molecular tagging of aroma gene.

本研究利用四川新育成的七个香稻保持系(D香1B、D香2B、内香2B、内香4B、绵香2B、绵香3B、宜香1B)、一个香稻引进改良品种(泸香90)和一个非香型保持系为材料，研究了香稻保持系主要农艺性状和品质性状对品质、产量的影响，并且通过杂交群体构建对香稻香味性状进行了遗传分析。

In the study, 58 cotton cultivars with resistance to Fusarium wilt and Verticillium wilt which come from different years and provinces .

我国从20世纪50年代开展棉花抗病育种工作以来，已经育成了大量的抗病品种。

The DNA fingerprints of 4 biotypes of GM population from 7 locations were analyses by AFLP.Base on the fine mapping of resistance gene Gm6 against all 4 Chinese GM biotypes by RAPD and SSR methods respectively,the STS markers and SSR markers linked to gene Gm6 were used for breeding through marker assisted selection.Some new resistant germplasm with Gm6 gene were created.And 6 cultivars and 6 lines of two-line hybrid rice and 1 line of three-line hybrid rice against GM were bred and extended to the farmer.The technique system of MAS for resistant varieties against Asian rice gall midge was set up at Guangdong province of China.

用AFLP方法对从中国广东省7个地点采集的4个生物型的DAN指纹进行分析；在对用RAPD和SSR技术分别对抗中国4个稻瘿蚊生物型的基因Gm6精细定位基础上，用与Gm6紧密连锁的STS和SSR标记开展分子标记辅助育种，创造了一批抗稻瘿蚊的新种质，包括育成了6个栽培稻和6个二系杂交稻和1个三系杂交稻并在农户试种，在中国广东成功地建立了分子标记辅助选育抗稻瘿蚊品种的技术体系。

The increase in photosynthetic rate was due to the increase in apparent leaf mesophyll conductance.

随着品种产量的增加，单叶净光合速率显著增加且与产量呈正相关，光合速率增加主要是由于品种表观叶肉导度随育成年代推延而显著增加所致。

During the past five decades, Percy and his colleagues have bred andreleased heat-tolerant and heat-avoidant pima lines, which thecommercial seed industry has used to create new varieties that canwithstand extreme temperatures.

在过去的50年间，（ Percy和他的同事们已育成并释放耐热和耐热回避比马线，其中商业种子产业已用於创造新品种，能够承受极端的温度。

In both the commercialized varieties and regional trial varieties, 11 alleles and 13 different allelic compositions were found.

在育成推广品种和参试品种中，等位基因变异均为11个；而亚基组成类型则分别为16个和13个。

For understanding the yield and quality changes of spring wheat piled up in field after reaping in Qinghai province, we selected Qingchun 533, which was planted widely in Qinghai province, and Plateau 205(susceptible to preharvest sprouting), Plateau 115, Plateau 448 and Plateau 314 which were bred by our institute, piled up them as the quomodo farmer used, sampled them every nine days, and mensured yield, SDS sedimentation value and falling number value to trick the changes of wheat.

为了解青海省春小麦收割后田间堆放期间产量和品质的变化，选择近年育成的春小麦品种&高原205&、&高原115&、&高原448&和&高原314&以及曾为青海省主栽品种的&青春533&为材料，收刻后以农民常用的田间堆放方式进行堆放，每隔9d对其进行采样，测定产量、SDS沉淀位和降落数值的变化。

The Numbers of callusing in 4 weeks exhibited extensive variation from 16.7-100%, 18.3-100%, and 4 1.7-100% in local, cultivars and families populations, respectively.

在地方品种、栽培品种和新育成品系中，半愈期都表现了广泛的变异。最短的6天就达到半愈期，最长的直至4周的培养试验结柬，都没有达到半愈期。

The Landrace has been used to cross with older breeds and, as a result, some new breeds have been formed.

用丹麦种长白猪同老的品种杂交，结果育成了些新品种。

The Landrace has been used to cross with older breed s and, as a result, some new breed s have been formed.

用丹麦种长白猪同老的品种杂交，结果育成了些新品种。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
