Three types of sixteen soybean crosses including indeterminate×semideterminate(Ⅰ·Ⅱ)、indeterminate×indeterminate (Ⅰ·Ⅰ) and semideterminate×semi-determinate(Ⅱ·Ⅱ)Were used for investigation of the inheritance of internode length and the relationships with other characters. The results indicated that the length internodes Ⅰ_(15) was the longest of F_1 and F_2 populations for all crosses. The numbers of transgressive-parent types Ⅰ·Ⅰ and Ⅱ·Ⅱ crosses were larger than that of type Ⅰ·Ⅱ crosses, but the mid-parent...

Three types of sixteen soybean crosses including indeterminate×semideterminate(Ⅰ·Ⅱ)、indeterminate×indeterminate (Ⅰ·Ⅰ) and semideterminate×semi-determinate(Ⅱ·Ⅱ)Were used for investigation of the inheritance of internode length and the relationships with other characters. The results indicated that the length internodes Ⅰ_(15) was the longest of F_1 and F_2 populations for all crosses. The numbers of transgressive-parent types Ⅰ·Ⅰ and Ⅱ·Ⅱ crosses were larger than that of type Ⅰ·Ⅱ crosses, but the mid-parent types were fewer than type Ⅰ·Ⅱ crosses, The internode length, at low and up parts of type Ⅰ·Ⅱ cross, at the middle part of tyPe Ⅰ·Ⅰ cross, at the mid-low and up parts of type Ⅱ·Ⅱ crosse, of parent plants had significant and highly significant positive correlations with number of pods per node of F_1 and F_2 populations respectively. Inheritance of internode length is relatively high for all three types of crosses, indicating that the character is stable and can be selected at early generations.

本文以无限×亚有限(Ⅰ·Ⅱ)、无限×无限(Ⅰ·Ⅰ)及亚有限×亚有限(Ⅱ·Ⅱ)三种类型16个大豆组合为材料,研究大豆植株节间长度的遗传及其与其他性状的关系。试验结果表明:各类组合的F_1和F_2代节间长度最高值均在Ⅰ_15节。Ⅰ·Ⅰ和Ⅱ·Ⅱ组合超亲类型均大于Ⅰ·Ⅱ组合,倾亲类型均少于Ⅰ·Ⅱ组合。Ⅰ·Ⅱ组合亲本植株下部,上部节间长度与F_1和F_2代每节荚数呈显著、极显著正相关。Ⅰ·Ⅰ组合亲本植株中节间长度与F_1和F_2代每节荚数呈显著、极显著正相关。Ⅱ·Ⅱ组合亲本植株中下部、上部节间长度与F_1和F_2代每节荚数呈显著、极显著正相关。各类型组合F_1和F_2代各节节间长度均表现遗传力较高。说明每节节间长度是一个比较稳定的性状,从早代就可选择。

Six wheat varieties with representativeness as experinmental parents were hybridized completely in two ranks according to Griffing Method the 2nd,and the grain output and the grain constitutional characters of a single plant of Hybrid F 1 were analyzed in hybrid advantage,parent relation and etc..The results showid:(1)the hybrid advantage of grain output of a single plant of Hybrid F 1 was the strongest,and the other four characters were as the following:single grain weght>grain number of single plant>single grain number>thousand kernel weinght.(2)Parent and son weer obviously relative when single grain number was on the LP,the relation of parent and son of the other four characters on different parent types did not reach the obvious level.(3)Improving grain output of single plant mainly depended on increasing grain number of single plant,then single grain weight and thousand kernel;Single grain number contributed smaller to grain output of single plant.

以6个具有代表性的小麦品种(系)为供试亲本,按照Grifing方法2进行完全双列杂交,对杂种F1的单株籽粒产量及其构成性状(单株粒数、单穗粒数、单穗粒重、千粒重)分别进行杂种优势分析、亲子相关分析及通径分析。结果表明:(1)杂种F1的单株籽粒产量杂种优势最强,其它4个性状依次为单穗粒重>单株粒数>单穗粒数>千粒重。(2)单穗粒数在低值亲本(LP)上亲子间呈显著正相关,其它4个性状在各亲本类型上亲子间的相关均未达到显著水平。(3)单株籽粒产量的提高主要依赖于单株粒数的增加,其次是单穗粒重和千粒重,单穗粒数对单株籽粒产量的贡献较小。

Since 1993, many intercross experiments were done to get fine form Seabuckthorn for ecological and economic benefits. The results showed the best properties of ecology and economy clones were the cross varieties of H.rhamnoides subsp. Mongolica ⅹ H.rhamnoides L.subsp.Sinensis Rousi. In this type, different parent types would have different heterosis. A best clone was 'WulanSalin' as female and 'Ningfeng' Chinese Seabuckthorn as male parent. The fine form clone was bred form F1 colony. Using 'WulanSalin'...

Since 1993, many intercross experiments were done to get fine form Seabuckthorn for ecological and economic benefits. The results showed the best properties of ecology and economy clones were the cross varieties of H.rhamnoides subsp. Mongolica ⅹ H.rhamnoides L.subsp.Sinensis Rousi. In this type, different parent types would have different heterosis. A best clone was 'WulanSalin' as female and 'Ningfeng' Chinese Seabuckthorn as male parent. The fine form clone was bred form F1 colony. Using 'WulanSalin' as female and 'Ningfeng' Chinese Seabuckthorn as male parent, the seed orchard was built and crossbreeding seeds were gotten. The value of Seabuckthorn would be increased when using those cross bred varieties.

从 1993年开始 ,为选育生态与经济效益兼顾的沙棘良种 ,进行了多种类型的杂交试验 ,其中“蒙古沙棘×中国沙棘”最有价值。在这个杂交组合中 ,亲本选配不同 ,杂种优势程度有别 ,以“乌兰沙林”为母本 ,以中国沙棘丰宁种源优良雄株为父本 ,效益最为显著。从F1代杂种群体中 ,选出了优良无性系品种“华林 1号”等 ,同时用其双亲建立杂交种子园 ,生产杂交种子。用这些杂交种营造沙棘林 ,可显著提高沙棘的栽培利用价值
