育成品种

Allelism in vestigation of genes resistante to Fusarium wilt in cotton suggested that there were 2 genes(assigned symbols Fw1 and Fw2)in 5 cultivars used.

1995-1996年，对我国育成的有代表性的5个抗病品种进行抗枯萎病基因的等位性测定。结果表明：在所选用的5个抗病品种中至少存在两个不同的抗病基因(暂定名为Fwl和Fw2)。

It had the advantages such as bumper and steady yield, earliness (1.92 days earlier than CK) and good adaptability.

但目前国内已育成的杂交优质油菜品种多为双低品种，尚未有双低高蛋白杂交油菜品种应用于生产。

As for modem zebu breeds ,. taurus also highly contributed to their formation , except for the Asian zebu .

对现代的瘤牛品种而言，除亚洲瘤牛品种外，普通牛对其他瘤牛品种育成的贡献同样高。

As for modem zebu breeds , B . taurus also highly contributed to their formation , except for the Asian zebu .

对现代的瘤牛品种而言，除亚洲瘤牛品种外，普通牛对其他瘤牛品种育成的贡献同样高。

Of the 36 tussah silkworm varieties, the Nei's genetic diversity index was 0.3243±0.1515, and Shannon information index was 0.4871±0.1975, suggesting that bivoltine tussah silkworm varieties are still rich in genetic diversity even having been conserved in the same place for quite long time. Nei's genetic identity of the 36 varieties ranged from 0.4959 to 0.8347, 96.59% of which was above 0.6, revealing large similarity between different varieties. A clustering analysis showed that these varieties formed two separate clades, one of which included varieties bred by the institute and the other included imported varieties from other provinces or countries.

供试品种资源的Nei氏遗传多样性指数为0.3243±0.1515，Shannon信息指数为0.4871±0.1975，表明长期同地保存的二化性柞蚕品种资源同样具有丰富的遗传多样性；供试品种的Nei氏遗传一致性范围在0.4959~0.8374之间，达0.6以上的占96.59%，表明多数品种资源的相似程度较高。36份品种资源分别以辽宁省蚕业科学研究所育成种为主和以国内外引进种为主聚为两大类群。

Seveteen fine biovotine female lines also had been bred out after 5～10 generations selecting directly to the bivoltine genetic resources, which included 8 Chinese female lines, 8 Japanese female lines and 2 hybrid female lines. These female lines could be reproduced easily by asexual reproductive way, their rate of asexual developed eggs were high with only female generations and economic characters were also stability.

采取直接利用无性繁殖性状较优良的二化性现行品种资源构建雌蚕无性繁殖系的方法，经5~10代的无性繁殖继代选择，初步育成了17个雌蚕无性繁殖品系，其中中系品种8个，日系品种7个，杂交种2个。

Based on incomplete statistics, by use of germplasms from INGER nurseries, six inbred varieties and 17 rice hybrids have been developed and released in commercial production for years and brought great economic and social profits in Guangxi province.

据不完全统计，利用INGER部份优良种质，进行系统选育和杂交育种，育成通过广西农作物品种审定并推广的品种6个，杂交稻组合17个，这些品种和组合在广西水稻生产上已大面积推广，取得了巨大的社会和经济效益。

Three Chinese and Japanese female lines had been bred out after about 10 generations selecting and improving to the materials, which were obtained by crossing the commercial races and the univoltine female races introduced from Russia.

利用俄罗斯引进的雌蚕无性繁殖系与我国实用品种杂交的方法，经过10代左右的连续无性繁殖继代选育，初步育成了中系雌蚕品种无3、无5、无7和日系雌蚕品种无4、无8、无10。

Fifty-two China-bred and introduced cottons with Fusarium and Verticillium wilts resistance were used to study their pedigrees and the effects of pedigree proportion on yield components. The results indicated that Deltapine and Stoneville descents contributed to the most of the varieties in proportion, followed by Foster.

对我国引进和育成的52个抗枯、黄萎病品种的系谱及其对产量性状的影响进行分析，结果表明岱字棉与斯字棉血统在52个品种中占有较大的比例，其次是福字棉，而其他品种的血统较少。

Dendrogram analysis showed genetic relationships among those varieties which have the same genetic resources. Therefore, t...

聚类分析表明，具有相同骨干亲本的育成品种遗传距离较近，这与以往的农艺性状研究及生理生化研究结论相符。

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。
