摘要/Abstract

摘要：

李是全球分布和栽培最广泛的果树之一，主要分为欧洲李（P. domestica）和中国李（P. salicina）两种。中国李起源于中国，具有较高的遗传异质性和果实性状遗传变异的丰富性。据推测，中国的长江流域地区仍有野生中国李的分布。在我国古代，许多书籍中都有李的栽培和品种记载，如秦汉、晋代、北宋和明代。国外也有许多书面记载李的起源和品种，如希腊、法国、芬兰、捷克和俄罗斯。自罗马时代以来，李已逐步传播到欧洲大陆。为了改善李果实品质、提高商品性以满足市场需求，一直在不断地培育新的李品种。世界上最早关于欧洲李品种的记载中选育出成熟期最早的品种，如‘Reine Claude’‘Early Rivers’‘Early Transparent Gage’‘Czar’‘Monarch’和‘Tresident’，目前仍广泛栽培。在中国，已经自主育成并经过品种审定且正式发表的李品种有88个。尽管世界各地的种植者、水果市场和消费者对李品种的改良需求各不相同，但育种性状包括果实大小、果皮颜色、多酚类物质、可溶性固形物、果实成熟期、抗寒性和抗病性能力等，受到共同关注。李育种方式从传统的育种手段，到分子辅助育种、组织培养和转基因育种不断演变。通过育种手段的不断改进，育出许多鲜食品质好、耐贮藏、货架期长和适应性好的优良品种，推动了世界李产业的发展。中国是全球最大的李生产国，李的产量占全球总产量的54.94%，栽培面积占全球总面积的74.75%。我国拥有丰富的李种质资源，这为李的育种创新提供了物质基础。而广泛的地理分布和栽培利用则为李新品种的应用提供了广阔的市场潜力。为了进一步发挥我国李种质资源的优势，提高我国李育种的核心竞争力，本文将梳理世界李的起源、传播、早期栽培利用、育种研究进展以及主要性状的遗传规律，并提出现代李育种策略。

Abstract:

Plum is a significant fruit tree worldwide, with the two main species being P. domestica and P. salicina. Chinese plum, originating from China, exhibits high genetic heterogeneity and abundant genetic variation in fruit traits. It is speculated that wild Chinese plums still exist in the Yangtze River basin. Throughout Chinese history, the plum cultivation and varieties were recorded by many secretaries of the Qin Dynasty, the Han Dynasty, the Jin Dynasty, the Northern Song Dynasty, and the Ming Dynasty. Similarly, in other countries, such as Greece, France, Finland, the Czech Republic, and Russia, there are written records of plum, describing its origin and 14 varieties. Plum was gradually introduced into the European continent during the Roman era, and numerous new varieties have since been cultivated to improve the fruit’s quality, commercial value, and meet market demand. There were currently 88 independently bred plum varieties in China that have passed variety approval and been officially published. Breeding traits of common concern include fruit size, peel color, polyphenols, soluble solids, fruit maturity, cold resistance, disease resistance, etc. Breeding methods range from traditional methods to molecular-assisted breeding, tissue culture, and transgenic breeding. Many excellent varieties with good fresh food quality, storage and transportation resistance, and adaptability have been bred through continuous improvement of breeding methods, promoting the development of the global plum industry. China is the world’s largest plum producer, accounting for 54.94% of total production and 74.75% of total cultivation area worldwide. The rich natural resources of plum in China provide solid material and diversity guarantee for germplasm exploration and breeding application. To further strengthen the international advantages of plum germplasm resources and cultivation areas in China, and to enhance the core competitiveness of national breeding, this study reviewed the global history process of plum breeding and improvement, including the origin, dissemination, early cultivation history of plum in the world, recent research on the main breeding traits, and commercial breeding strategies for modern plum.

李痘病PPV病毒主要分离株及特征"

分离株 Strain	病毒最初发生地 Virus original country	主要寄主 Main host	说明 Note
PPV-D（狄德罗） PPV-D (Dideron)	法国 France	杏、桃、李 Apricot, Peach, Plum	PPV-D是欧洲西部传播最严重的分离株，也在智利和美国（宾夕法尼亚州）发生。该分离株不通过种子传播，且蚜虫-载体效率较低 The PPV-D isolate is widely spread throughout western Europe, as well as in Chile and the United States (specifically in Pennsylvania). This isolate is not transmitted through seeds, and its efficiency in being carried by aphids is low
PPV-M（马库斯） PPV-M (Markus)	希腊 Greece	李、杏、樱桃 Plum, Apricot, Cherry	PPV-M是欧洲南部，东部和南部最常见的分离株。菌株传播迅速并且很难消除。该菌株通过蚜虫迅速传播 PPV-M is the most prevalent isolate found in southern, eastern, and southeastern Europe. This strain has a rapid spread rate and is notoriously difficult to eradicate due to its persistent nature. It is primarily spread through aphids, leading to an increased risk of transmission
PPV-Rec（重组） PPV-Rec (Recombinant)	捷克 Czech	杏、李（包括樱桃李、黑刺李）、樱桃 Apricot, Plum (including cherry plum, black thorn plum), Cherry	可能是PPV-M和PPV-D分离株发生了同源重组，导致其在欧洲东部地区广泛传播，且具有高致病性和强的蚜虫传播能力 There is a strong possibility that homologous recombination between isolates of PPV-M and PPV-D has occurred. This strain is particularly prevalent in countries and regions of Eastern Europe, and possesses high pathogenicity and a strong ability to be transmitted by aphids
PPV-EA（埃尔阿马尔） PPV-EA (El Amar)	埃及 Egypt	李、桃 Plum, Peach	该病毒株在北非地区普遍存在，与PPV-M分离株具有相似的特征 This strain is commonly found in North Africa and shares similar characteristics with the PPV-M isolate
PPV-C（樱桃） PPV-C (Cherry)	摩尔多瓦 Moldova	樱桃 Cherry	它在欧洲东部流行 This strain is widespread in Eastern Europe
PPV-CR（俄国樱桃） PPV-CR (Cherry, Russian)	俄罗斯 Russia	酸樱桃 Sour cherry	它是发生在俄罗斯地区的第二种适应于樱桃的PPV分离株，PPV-C之后出现 This strain, which originated in Russia, is the second isolate after PPV-C that has adapted to infect cherry trees
PPV-W（威诺纳） PPV-W (Winona)	加拿大（安大略） Canada (Ontario)	李 Plum	近年来，该毒株在拉脱维亚和乌克兰的李树上被发现，并传播至俄罗斯地区。与其他分离株相比，其遗传差异明显 In recent years, this strain has also been found on plum trees in Latvia and Ukraine, and has spread to Russia. It shows significant genetic differences from other isolates
PPV-An（Marcus祖先） PPV-An (Ancestor Marcus)	阿尔巴尼亚 Albania	李、杏、樱桃 Plum、Apricot、Cherry	该分离株的全基因组序列符合PPV的进化假说，表明它是PPV-M分离株的祖先 The full-length genome sequence of this isolate supports the evolutionary hypothesis of PPV, indicating that it is the ancestor of the PPV-M isolate
PPV-T（土耳其） PPV-T (Turkey)	土耳其 Turkey	杏 Apricot	由HC-Pro基因重组事件产生 Recombination events have occurred in the HC-Pro gene
PPV-CV（伏尔加樱桃） PPV-CV (Cherry, Volga)	俄罗斯 Russia	酸樱桃 Sour cherry	它的3'末端基因组序列与已知的分离株高度不同 Its 3' end genome sequence differs significantly from known isolates
