Genetic improvement of the cultivated soybean may be achieved by trans-fering desired genes from G. soja to G. max with backcrossing method. However, additional backcrossing with G. max usually caused the progenies to have a decreasing amount of G. soja germplasm and then most of good genotypes with desired G.soja genes might be lost (such as high protein content). In this study, an attempt was made not only to discard the undesired characters of G. soja (such as twining stem and black seed coat color)...

Genetic improvement of the cultivated soybean may be achieved by trans-fering desired genes from G. soja to G. max with backcrossing method. However, additional backcrossing with G. max usually caused the progenies to have a decreasing amount of G. soja germplasm and then most of good genotypes with desired G.soja genes might be lost (such as high protein content). In this study, an attempt was made not only to discard the undesired characters of G. soja (such as twining stem and black seed coat color) but also to introduce high protein genes from G.soja to cultivated soybean. The results of the study were as follows: 1. The dwarf character of soybean was controlled by a main receessive gene. With the gene action, viny habit also existed as a qualitatively inherited character. Twenty five percent of dwarf and erect plants were observed in F_2 population in the cross between dwarf variety and G.soja. 2.Dwarf and erect characters were significantly correlated with yellow seed coat, deep green color of leaves and earlier maturity. It would be more effective to select phenotypes similar to cultivated variety by discarding vinning plant in earlier growth period basing on leaf color. 3.The desired phenotyes (with high protein, erect stem and yellow seed coat) in dwarf variety ×G. soja population were more than 5.05%, while those in backcrossing population of Taller Variety × G. soja were only 0.04% to 0.9%. 4.The time needed for obtaining improved progenies in dwarf variety × G. soja cross was far shorter than that in the taller variety × G. soja cross with an backcrossing generation.

本研究用携带矮杆基因的矬大豆直接与野生大豆杂交.目的是研究矮杆基因抑制蔓生性等野生不良性状的遗传效应,确定用矮杆基因克服野生不良性状的价值.结果表明:矮杆基因是受主效基因控制的隐性性状,受其作用,蔓生性与直立性表现为3∶1分离,F_2代产生1/4的直立个体,证明利用矮杆基因克服蔓生性是十分有效的方法.同时,矮杆直立性还与淡色种皮、深色叶以及早熟性有显著相关,对于在生育早期根据叶色淘汰蔓生型,集中选择符合栽培要求的直立类型有一定作用.试验还证实,早代回交有降低出现高蛋白质含量基因型频率的趋势.并且,一次回交只能产生1.9~7.9%的直立株,优良表现型也只占总体的0.04~0.98%.而用矮大豆作亲本的组合后代不需进行回交,优良类型的比例即可高达5.05%.此外,用矮杆大豆和野生种杂交比用普遍品种杂交再回交对野生不良性状的改良周期至少缩短1~2年.

In order to define suitable shading way of ginseng, the photosynthetic rate and root absorptivity of ginseng were measured bY using ~(14)C and ~(32)P isotops as tracers under various light intensity. The result showed that saturation light intensity of ginseng was 20Klx or 25% LTR (light transparent rate). When ginseng grown under light intensity more than 20 Klx, photorsynthetie rate lowered, color of leaves changed yellowish, as'ginseng grown under 30% LTR, that root of ginseng absorbed the a mount of...

When ginseng grown under light intensity more than 20 Klx, photorsynthetie rate lowered, color of leaves changed yellowish, as'ginseng grown under 30% LTR, that root of ginseng absorbed the a mount of ~(32)p was lower than under 10% LTR. Therefore suitable shading way of ginseng should extend duration of sunshine, the greatest light intensity should not be more than 25%.

为了明确人参高产的适宜遮荫方式,用~(14)C和~(32)F同位素示踪法测定了不同透光棚下人参的光合速率和根系吸收性能。试验证明人参的光饱和点约为20Klx,相当于透光率25%。超过20Klx光照的人参,光合速率下降,叶包变黄;透光30%处理的人参,根系吸收~(32)P量也较透光10%处理有所下降。因此,适宜棚式的设计,应是延长接近饱和光强的日照时间,而最大透光率以不超过25%为宜。

On the basis of hawthorn germplasm investigation in China, which was carried out during 1979-1984, we conducted a thorough study on the description system of hawthorn germplasm resources from 1985 to 1987. The differences among and within the varieties, and the role of each character in their identification were demonstrated. Through observation on about 100 characters of 40 hawthorn varieties, we discovered that,since there are no significant difference in 19 characters ( accounting for 30% in the previous...

On the basis of hawthorn germplasm investigation in China, which was carried out during 1979-1984, we conducted a thorough study on the description system of hawthorn germplasm resources from 1985 to 1987. The differences among and within the varieties, and the role of each character in their identification were demonstrated. Through observation on about 100 characters of 40 hawthorn varieties, we discovered that,since there are no significant difference in 19 characters ( accounting for 30% in the previous items ) , such as young stem color, stipule shape, number of stamens between varieties, they should not be included in survey. Many characters, such as leaf thickness, size and color of leaf grand, dent distance, dent base distance arc relatively atable within each variety,but different considerably between varieties. These 33 characters ( accounting for 43 % in revised items ) should be listed in the investigation items. The suitable sampling methods, investigation standards and the methods and indices for description were also studied and, as a result, a description system of hawthorn germ-plasm resources was established according to the demand of computer management.It laid a priliminary basis for studying hawthorn germplasm resources.

作者在1979-1984年参加全国山楂资源考察的基础上,于1985-1987年对当时拟定的性状描述系统进行了较深入的研究。通过对40个代表性山楂品种近百个性状在品种间和品种内变异的研究,发现原调查项目中幼茎颜色、托叶形状、单花雄蕊数等19个项目品种间无显著差异,对鉴别品种无价值,应予删除,占原调查项目 63项的30%。原调查项目中未列,但品种间差异显著,有助于鉴别品种的项目33个,建议增列,如叶片厚薄、叶缘腺体大小和颜色、叶刻距、刻基距等,占现有描述系统此类调查项目77项的43%。研究了资源调查中的取样部位、方法和取样数量问题,并按种质资源数据电子计算机管理的要求,建立了山楂种质资源性状描述系统、鉴定项目及其分级归类标准、数据库结构及数据类型、不同数据项的合理容量等,为山楂种质资源的系统研究奠定了初步基础。
