    摘要:

    梨是我国落叶果树的第二大树种。近几年来,在梨种质资源评价挖掘、性状遗传发育机理以及特色多样化品种培育等方面取得了诸多重要进展,主要研究结果如下:①中国原产的东方梨有 13 个种,其中基本种只有中国豆梨、台湾豆梨、川梨、砂梨和秋子梨等 5 个种,而白梨、麻梨和褐梨等 3 个种系杂种起源,不属于基本种;②我国优质早熟梨新品种选育研究取得了突破性进展,成就斐然,早、中、晚熟梨的比例已由 1994 年的 7:23:70 调整到 2006 年的 20:28:52,近 10 年育成的早熟品种比例接近 50%;③新疆库尔勒香梨优质、耐贮的特性遗传能力很强,是梨品质育种不可或缺的珍贵种质,而复杂的遗传背景和丰富的遗传多样性是亲本选择进行梨品质育种的关键;④优质耐贮极晚熟梨品种的选育与推广,是满足优质大梨市场周年供应、提振消费者消费信心、撬动我国梨产业高效发展的关键。针对目前的研究现状,今后应在如下两个研究领域下功夫,一是进一步加强优质耐贮极晚熟梨新品种的选育,构建以优质耐贮极晚熟梨新品种为主、优质早、中晚熟品种配套的品种结构,以满足市场的多样化及周年供应需求;二是利用现代分子生物学技术,从转录、翻译及修饰等多个层面进一步探讨品质性状发育机理,为梨品质育种提供理论支撑。

    Abstract:

    Pear is the second largest deciduous fruit tree in China. In recent years, many important advances in China have been made in the evaluation and exploitation of pear germplasm resources, unlocking the mechanism of genetic development and breeding of characteristic cultivars. The main achievements contained: (1) defining 13 species of oriental pear originated in China, of which five belong to primary species including Pyrus callryana Dene, P. koehnei Schneid, P. betulaefolia Bunge, P. pyrifolia Burm and P. ussuriensis Max, while three species composing of P. bretshneideri Rehd., P. serrulata Rehd. and P. phaeocarpa Rehd. are hybrids; (2)Breakthrough progress in breeding for high-quality early-maturing pear cultivars. The proportion of early, middle and late ripening pear cultivars were 20:28:52 in 2006 (relative to 7:23:70 in 1994), and the early ripening pear cultivars accounted for nearly 50% in the past 10 years. (3) Korla pear is an indispensable germplasm for pear quality breeding because of its strong hereditary ability ofhigh quality and storage tolerance. Complex genetic background and abundant genetic diversity are the key factors for parent selection in pear quality breeding. (4) Breeding and popularization of high-quality and late-maturing pear cultivars is the key to satisfy the annual supply of high-quality pear market, boost consumer confidence and promote the efficient development of pear industry in China. In view of the current status, two subjects are suggested in the future researches, including: (1) Constantly breeding for elite pear cultivars that represent high-quality, storage-tolerant and extremely late maturity, in order to meet the diversified demands in market; (2) unlocking the development mechanism of quality traits from transcription, translation and modification, by taking use of the modern molecular biology technologies, which might provide the theoretical basis for pear quality breeding.
