Since 1953,progenies of F_2 to F_6 generations of soybean crosses between Man-tsang-chinand Nanking Early Green had been used for selection with both mass and pedigree selectionmethods.The progenies were selected for:3 different dates of maturity,3 different size ofseeds and determinate and indeterminate of pod bearing habit.The effectiveness of the twoselection methods were compared from F_3 to F_6 generations on the basis of maturity,podbearing habit,and seed size.On 1957,hybrids of each cross of the...

Since 1953,progenies of F_2 to F_6 generations of soybean crosses between Man-tsang-chinand Nanking Early Green had been used for selection with both mass and pedigree selectionmethods.The progenies were selected for:3 different dates of maturity,3 different size ofseeds and determinate and indeterminate of pod bearing habit.The effectiveness of the twoselection methods were compared from F_3 to F_6 generations on the basis of maturity,podbearing habit,and seed size.On 1957,hybrids of each cross of the other 4 soybean crosseswere divided into two equal parts and subjected separately to the mass and pedigree selec-tions with similar selection purposes until F_5 generation.On F_4 and F_5 generations,char-acters of plants obtained by the two different methods were measured and compared.On F_6generation,seeds from each of the selected F_5 plants were grown as line and the characters,including yield capacity,were recorded and compared.The experimental results pointed out that the selection effectiveness of the two methodswhich affected on the characters of maturity,pod bearing habit,plant height and seed size,are quite similar,In certain cases,materials obtained from mass selection seemed to mature1-2 days later,but in some other years the cases were reversed.Materials of one cross ob-tained by pedigree method showed a tendency of possessing taller plant height.The present study pointed out that,a bulk breeding system consisting of selecting theearly generation hybrid materials with mass selection method followed by an individual plantselection on F_5 generation,is an effective and plain method for soybean breeding.Thereasons why such a system is as effective as the predigree breeding system are as follows:1.Characters subjected to mass selection such as date of maturity,pod bearing habit andplant height,are easy to distinguish in the field.2.During the course of mass selection,the direction of selections on date of maturity,plant height and pod bearing habit are quitethe same as that of natural selection and thus makes the mass selection effective and efficient.3.Date of maturity,plant height and pod bearing habit of soybeans are characters withhigher heritability,and thus they are suitable to be subjected for mass selection during theearly generations.Characters with lower heritability,such as yield and oil content,may besubjected to single plant selecion in F_5 or later generations.4.An ecological type adaptableon date of maturity,pod bearing habit,seed size and plant height,is an adequate material forhigh yield selection.Mass selection of soybean hybrid materials can furnish such adaptableecological type and thus to ensure the successive individual plant selection for securing thehigh yield lines.From 1952,we also started to subject the residual portion of hybrid materials of 21 soy-bean crosses of our pedigree breeding work to bulk breeding system.The final result of theparallel consecutive selection pointed out that the best variety N.E.No.4 had been bred outthrough the use of bulk breeding system.Therefore,it is also preferable to emphasize thatthe effectiveness of the bulk breeding system is quite convenient for handling the hybrid materialsin our practical soybean breeding works.rks.

通过多年的系统试验,证明对大豆杂交早期世代的材料,用混合选择法针对成熟期、株高、结莢习性,以及种粒大小等性状进行定向的选择,效果并不次于系谱选择法,但却简便易行。大豆杂交材料经过数代的定向混合选择,便形成为能适应当地条件与要求的优良生态类型。在这个基础上,再用个体选择法进行选择,能较有保证地选育出高产优质抗性強的优良品系。

The anomalous pollen grains in vivo at the frequencies of 2.61% and 6.81% respectively were found in anthers of two hybrid materials of wheat from which we had obtained the higher frequencies of induction of pollen embryos in anther culture in.the past few years.This indicated that the pollen dimorphism also presented itself in the anthers on wheat plants.A comparative cytological study of develop- ment of anomalous pollen grains in vivo and of the early stages of the formation of pollen embryos in vitro was carried out and the results suggest that in cytological details there is an obvious similarity between them.This reveals the possibility that the pollen embryos night derive itself from the anomalous pollen grains in wheat as in the other plants.Therefore,it was considered that the appearance and frequency of the anomalous pollen grains could show the sensibility of the development of microspores to the changes of various internal and external factors.The significance of the sensibility for the formation of pollen embryos in anther culture of wheat is discussed.

在两个小麦杂种材料的活体花药中,发现相当数量的不正常花粉,频率分别为2.61%和6.81%。这表明在小麦的活体花药中也存在花粉二型性现象。对活体花药中不正常花粉的发育和花药培养中花粉胚形成的早期阶段进行了细胞学对比研究,结果表明,此二者在细胞学上具有明显的一致性。因此在小麦中也如同在其他植物中一样,花粉胚可能起源于不正常花粉。作者认为活体中不正常花粉的出现和频率可能表示植物小孢子发育对内外各种因素变化的敏感性。讨论了这种敏感性对于小麦花药培养中花粉胚形成的意义。

This paper deals with the hybridization between Hordeum vulgare andTriticum aestivum conducted from 1979 to 1982.Hybrid seeds were obtainedamong 23 crosses when Hordeum vulgare was used as female parent withan average seed setting rate of 2.8%.Early No.3、PF51811、PF5801(barley)when crossed with a Chinese spring wheat,Beijing 772,showed ahigher seed setting rate than the others.Wheat cultivars with timopheevicytoplasm were found to be more compatible with barley.After beinginoculated on the culture medium 50-70% of young hybrid embryos weredeveloped into plantlets.Hybrid plants resembled wheat more closely thanbarley in gross morphlogy and were completely self-sterile.The frequentoccurrence of pistilloidy in barley×wheat crosses made it necessary tomaintain the hybrid materials by backcrossing with wheat as the pollenparent.The F_1 plants had as expected 28 somatic chromosomes and showed usually28 univalents at meiosis in pollen mother cells.We also succeeded ininducing plant regenration from the calli derived from the young stemsof F_1 hybrids.

本文论述1979~1982年大麦与普通小麦杂交的研究结果。在以大麦为母本的23个杂交组合中得到了种子,平均杂交结实率为2.8%。其中以早熟3号、PF51811、PF5801大麦为母本,中国春和京722小麦为父本的组合,杂交结实率较高。带有提莫菲维细胞质的小麦品种与大麦也具有一定的杂交亲和性。接种在培养基上的杂种胚50~70%可以萌发长成小苗。杂种在植株形态上与小麦相似,完全自交不育,且普遍有雄蕊雌蕊化现象,只能通过小麦花粉回交才能保存后代。F_1植株体细胞染色体数为28个,大多数花粉母细胞减数分裂时显示出28个单价体。此外,我们还成功地从来自杂种F_1植株幼茎的愈伤组织再生出杂种植株,但未加倍,2n 仍等于28。
