It is diffcult to obtain hybrids by directly crossing tetraploid H. bulb-osum USSR or H. bulbosum Hangary and most hexaploids (T. aestivum) with a dominant male sterile gene. We have obtained a hybrid from the cross of wheat with a male sterile gene and Chinese spring monosomic 5B. This hybrid has proved well to serve as a bridge for producing intergeneric hybrids by crossing a male sterile plant of the intermediary hybrid with H. bulbosum barley. The practical values of this method are as follows: 1) not only...

It is diffcult to obtain hybrids by directly crossing tetraploid H. bulb-osum USSR or H. bulbosum Hangary and most hexaploids (T. aestivum) with a dominant male sterile gene. We have obtained a hybrid from the cross of wheat with a male sterile gene and Chinese spring monosomic 5B. This hybrid has proved well to serve as a bridge for producing intergeneric hybrids by crossing a male sterile plant of the intermediary hybrid with H. bulbosum barley. The practical values of this method are as follows: 1) not only a great deal of artificial emasculation work can be saved but the possible confusion caused by "pseudo-hybrids" may also be eliminated; 2) it will greatly promote the successful cross between aestivum wheat and H. bulbosum barley; 3) it. will enable us to put into use the materials of nuclear male sterile wheat with various backgrounds in distant hybridization.

四倍体苏联球茎大麦或匈牙利球茎大麦直接与六倍体显性核不育小麦进行杂交极难获得杂交种子。利用显性核不育小麦与中国春5B单体杂交产生居间杂种(F_1),再以居间杂种的不育株与球茎大麦进行杂交,就可能得到属间杂种。这种通过媒介法利用显性核不育基因进行复式远缘杂交的实用价值在于:(1)可以省却大量的人工去雄手续和排除可能出现的“假杂种”干扰;(2)利用中国春或其5B单体在远缘杂交中的可交配性。可促进普通小麦与球茎大麦的杂交成功;(3)可以使具有各种遗传背景的核不育小麦材料能够在远缘杂交中得到应用。

Our experimental results showed that the differentiation ability of pollen callus of wheat was gradually reduced with the increase in age. Subcultures of pollen callus had only slight effect on maintenance of differentiation ability of pollen callus. Preservation at low temperature could not only maintain the differentiating ability of wheat pollen callus at a given level for a long time but also had an enhancing effect on spontaneous chromosome doubling. High sucrose concentration was not suitable for the differentiation...

Our experimental results showed that the differentiation ability of pollen callus of wheat was gradually reduced with the increase in age. Subcultures of pollen callus had only slight effect on maintenance of differentiation ability of pollen callus. Preservation at low temperature could not only maintain the differentiating ability of wheat pollen callus at a given level for a long time but also had an enhancing effect on spontaneous chromosome doubling. High sucrose concentration was not suitable for the differentiation medium of wheat. 0.5mg/liter Kinetin was optimum. The comparison of the differentiating effect between 190-2 differentiation medium and modified MS medium showed that 190-2 medium was the better one for wheat anther culture. The differentiation frequencies of the pollen callus varied significantly with different genotypes of wheat.

小麦花粉愈伤组织年龄对分化的影响很大,随着年龄的增长其分化能力逐渐降低。继代培养的愈伤组织分化能力较之未继代培养的略有增加。低温保存既可使小麦愈伤组织在较长时期内仍能保持一定的分化能力,又有促进染色体自然加倍的作用。小麦分化培养基的蔗糖浓度不宜太高。激动素浓度以0.5毫克/升较为适宜。190-2分化培养基分化花粉植株的能力显著高于修改的MS培养基。愈伤组织的分化频率因供试小麦材料基因型的不同而表现出明显的差异。

The data on the yield, number of grains per spike and weight of 1,000 kernels obtained from Wheat cultivar regional test in the Lower Yangtse Valley were used to group locations according to the similarity of genotype ×location effects by cluster analysis. Six or seven genotypes of wheat were planted in thirteen locations from 1979 to 1983 for four crop seasons. Distance coefficients(Euclidean distance)were estimated among all possible pairs of locations. Such an analysis would be useful for the selection of...

The data on the yield, number of grains per spike and weight of 1,000 kernels obtained from Wheat cultivar regional test in the Lower Yangtse Valley were used to group locations according to the similarity of genotype ×location effects by cluster analysis. Six or seven genotypes of wheat were planted in thirteen locations from 1979 to 1983 for four crop seasons. Distance coefficients(Euclidean distance)were estimated among all possible pairs of locations. Such an analysis would be useful for the selection of testing sites for early generation testing and for development of genotypes with wide or narrow adaptability.The weight of 1,000 kernels of check cultivar was the best data to group locations. The 13 locations were grouped into 10 clusters with respect to their Weight of 1,000 kernels of check cultivar distance in a 4-dimensional space (4 years).The groups were as follows:A.East to the Grand Canala.Eastern plain1. Suzhou, 2. Nantong(Rudong)b.Law ground of riverside3. Wujin, 4. Changshu, 5. Xinghuac. Seaboard sandy soil region6. Yancheng and DafengB.West to the Grand Canald. High sandy region7. Yangzhoue.

应用长江下游地区小麦品种区域试验1979—1983年4个小麦生长季的产量、每穗粒数和千粒重资料,分别按其基因型×地点效应的相似性进行聚类分析。6—7个小麦材料种在13个试点。计算各试点间所有可能成对的78个欧氏距离系数。此种分析有助于为选择确当试验地点以研究早期世代和品种适应性的宽窄提供参考。结果表明,本试验中区试地点分类上用对照品种多年多点的千粒重资料为变量,聚类效果较好。按其4年千粒重的距离,13个区试点可分为2片、6区、10组。一、大运河以东片。包括:(一)东部平原,有苏州、南通(如东);(二)沿河低地,有武进、常熟、兴化;(三)沿海砂土区,有盐城、大丰。二、大运河以西片。包括:(四)高砂土地区,有扬州;(五)丘陵区,有镇江、仪征,南京;(六)沿江、沿湖区,有江浦、金湖。最后根据聚类结果,对区试点的调整问题进行了讨论。
