Under the guidance of the Soviet Forestry Committee, there are20 scientific research institutes, among which the Soviet Forestry and Me-chanization Institute is a national institute facing the needs all over thecountry. In 1971, the National Central Institute of Forest Genetics andBreeding was established. Its merits and demerits are as follows: 1).

Under the guidance of the Soviet Forestry Committee, there are20 scientific research institutes, among which the Soviet Forestry and Me-chanization Institute is a national institute facing the needs all over thecountry. In 1971, the National Central Institute of Forest Genetics andBreeding was established. Its merits and demerits are as follows: 1). Thescale of field trials is larger and its duration is longer than those of othercountries. 2). The provenance test sites of many tree species are kept per-fect. 3). In the field of cross breeding, the research on poplars makesbetter achievements. 4). In the field of genetics they have taken a roundabout way in their work for a long time. They started the research on tissueculture, cell culture, gene transfer and isoenzyme at a later period. 5). Inthe field of forest insects and disease control, they paid attention to the microbial control.70% of the damaged area is treated with microbial agen-ts, and the Thuricide control accounts for 90%. There are at least 4 Thu-ricide formulations being produced. 6). In the field of wood process,the research and production of particle board develops quickly. From 1960-1987, the output of particle board increased by 4781.7%,and the board wasmainly used for the production of furniture. In addition, much attentionhas been paid to the researches on forest machinery, utilization of herbi-cide, forest ecology, tree physiology, forest biochemistry etc. There is ahopeful prospect in the research cooperation between our two countries,biological control of insects and diseases, exploitation and utilization ofnon-wood products, benefits of agricultural land shelterbelt, wood proces-sing. monitoring method for man-made boards, forest economics etc

苏联森林委员会下设20个科研机构。苏联在林木育种,病虫害的生物防治,林业机械化,刨花板生产等方面进展迅速。田间试验的规模大,长期稳定地保留试验现场是其林业研究的优势。林木遗传学研究由于走过一段弯路,目前处于起步阶段。微生物防治森林虫害的面积占70%。中苏两国在许多领域内具有开展合作研究的前景。

Near isogenic lines were important base for the construction of molecular genetic maps, QTLs location and molecular markers-assisted breeding. There were several methods for the selection of near isogenic lines including selection by multiple continuous backcross, isolation from mutants, selection in the multiple continuous backcross combined with molecular markers and selection from the materials of higher generation.Progress on the selection and application of near isogenic lines of the important crops was...

Near isogenic lines were important base for the construction of molecular genetic maps, QTLs location and molecular markers-assisted breeding. There were several methods for the selection of near isogenic lines including selection by multiple continuous backcross, isolation from mutants, selection in the multiple continuous backcross combined with molecular markers and selection from the materials of higher generation.Progress on the selection and application of near isogenic lines of the important crops was described.Moreover,combined with characters of forest trees, an idea was put forward which was that plants of Salix with short cycle of growth should be selected for the establishment of near isogenic lines and would become a model species for the genetic improvement of forest trees on the base of the near isogenic lines of Salix.

近等基因系是分子遗传图谱构建、数量性状基因定位及分子标记辅助育种的重要基础。近等基因系选育主要有连续多次回交选育法、从突变体中分离获得、结合分子标记技术检测连续回交选育法、杂交高世代群体材料中分离选育等方法。本文介绍了主要农作物近等基因系构建及应用的研究进展,并结合林木植物的特点,提出了选择生长周期较短的木本植物柳树为材料,构建近等基因系,在此基础上形成林木遗传学研究模式树种的观点。

Construction of forest trees' genetic linkage maps is different from that of other species due to trees' long generation, high heterozygosity and genetic load. Trees' high-performance genetic maps could be applied to comparative mapping of kindred tree species, a better understanding of genomic organization and evolution of forest trees, QTL mapping and molecular-assisted selection of trees' complex traits. Problems existing in forest trees' genetic mapping includes small mapping population, linkage equilibrium...

Construction of forest trees' genetic linkage maps is different from that of other species due to trees' long generation, high heterozygosity and genetic load. Trees' high-performance genetic maps could be applied to comparative mapping of kindred tree species, a better understanding of genomic organization and evolution of forest trees, QTL mapping and molecular-assisted selection of trees' complex traits. Problems existing in forest trees' genetic mapping includes small mapping population, linkage equilibrium in map construction and QTL mapping and an unsatisfied mapping strategy in which genetic characteristics of forest trees are not fully considered, all of which could been solved by using large mapping population, highly conservative marker systems and statistic methods suitable to mapping and genomic studies of forest trees.;

林木具有世代长、高度杂合、遗传负荷大等遗传特性 ,使其遗传图谱研究不同于其他物种。高质量林木遗传图谱 ,可进行林木近缘树种比较图谱研究 ,了解林木的基因组结构和进化历程 ,进行有效QTL定位研究及开展林木复杂性状的标记辅助选择。目前林木作图存在着群体较小 ,构建的图谱和定位的QTL存在连锁平衡 ,以及作图策略未充分考虑林木的遗传学特性等问题。扩大作图群体、选择高度保守的标记系统以及研究适合林木作图的理论和方法将有助于林木基因组研究向纵深发展
