摘要: [目的]为有效评价和利用葱属植物资源,挖掘优良性状,[方法]以国内仅分布于新疆的棱叶蒜为研究材料,对不同地理分布的45份棱叶蒜种质资源的形态性状进行遗传多样性分析。[结果]研究结果显示:棱叶蒜分布在81°09′N-86°38′N,48°15′E-43°15′E,海拔320-1896 m沿天山山脉以北及阿尔泰山以南的山地森林草原、干旱荒漠和干旱草原等七个生态区。15个数量性状变异系数介于21.19%-700.00%之间,遗传多样性指数介于0.10-1.68。株芽数目、株芽大小、鳞芽大小、鳞芽数目以及根系大小性状的总载荷量均在0.90以上。根系、鳞茎和花部性状特征与生境特点密切相关。[结论]棱叶蒜地域分布广,生境多样,适应性强,数量性状变异较大,遗传多样性丰富。

Abstract: In this study,the phenotypic traits of 45 A.caeruleum germplasm resources were analyzed by the genetic diversity in order to effective evaluation and utilization of Allium resources. [Result]The results showed that A.caeruleum distributed in mountain grasslands,arid desert and arid grasslands,81°09′N - 86°38′ N,48°15′ E - 43°15′E,altitude 320- 1896 m,along the north of the Tian Shan Mountains and the south of Altai Mountains that were divided into seven ecological zones. The coefficient of variation were between 21.19-700%,genetic diversity index were between 0.10 and 1.68 of 15 quantitative traits. The principal component analysis showed that the total loading of the bulbil number,bulbil size,bulblet size,bulblet number and root size was above 0.90,respectively. The differences appearing in root, bulb and inflorescence were among them response to their habitats. [Conclusion]A.caeruleum has geographically widespread distribution zones. Its habitat is diverse and the adaptation is strong. The result revealed that the broad genetic diversity existed among these quantitative traits.
