上个世纪90年代,北美灌木柳育种计划在纽约州启动,经过30多年的杂交、选育以及在美国中、北部的区域试验,选育了一大批高产、高抗的灌木柳栽培品种,目前很多品种在美国已商品化生产。在北美纽约州、宾夕法尼亚州等地,灌木柳被广泛用于工业污染地、垃圾填埋场的植物修复、公路防风雪篱以及生物质能源生产。尽管国际上在柳树重金属污染修复方面做了大量研究,筛选出很多对重金属具有高积累、耐性以及转移的品种,但是重金属积...
To identify factors involved in seed development of parthenocarpic tomato, the effects of combinations of crossing parents and crossing stage on seed development of parthenocarpic tomato were examined...
We carried out colchicine treatment of lateral buds and their grafting in some monoembryonic citrus cultivars to induce tetraploid plants. Among the grafted plants, 19 eutetraploid plants were obtaine...
The purpose of this study was to determine estimates of the general combining ability of parents and the specific combining ability of hybrids needed to develop high yielding cotton cultivars. Five co...
The genetic diversity of 41 parental lines popularized in commercial hybrid rice production in China was studied by using cluster analysis of morphological traits and simple sequence repeat (SSR) mark...
A lysozyme gene resistant to rice blast was transferred from the donor transgenic japonica rice Zhonghua 9 (D2-1-2) into a sterile line Pei’ai 64S(PA 64S) and restorer line 9311 of the two-line hybrid...
Textile manufacturers have raised concerns that mill performance of cotton (Gossypium hirsutum L.) has been compromised by transgenic technology. The objective of this study was to compare two transge...
摘要 以甘蓝型油菜(Brassica napus L, AACC,2n=38)Ogura细胞质雄性不育材料为母本,以不同白菜(B campestris ssp. chinensis Makino, AA, 2n=20) 自交系‘新选一号’和‘矮脚黄’为父本进行杂交,获得了杂种F1、BC1、BC2代。利用cDNA-AFLP技术对两种材料的不同回交世代BC1、BC2代与其亲本在蕾期的基因表达进行分析...
Using mRNA differential display technique, we investigated differential gene expression in hybrids relative to their parents in a diallel cross involving four chicken breeds in order to provide an ins...
