调查了四川及其周边地区(未包括青海省)野生草莓资源种类和地理分布,将收集的野生草莓资源进行迁地保存,并对其农艺性状、抗非生物和生物胁迫能力的变异进行了主成分分析。结果表明,四川及其邻近周边高海拔地区野生草莓主要分布在26°14’~33°22’N、96°57’~108°13’E、海拔823~4531m的垂直空间范围内。黄毛草莓(Fragaria nilgerrensisSchlecht.)、五叶草莓(F.pentaphylla Lozinsk.)、西南草莓(F.moupinensis(Franch.)Card.)和纤细草莓(F.gracilis Lozinsk.)是该区域分布的4个野生草莓种类,其中五叶草莓有红果和白果两个类型。黄毛草莓浆果具有特殊的蜜桃香气。株高、叶柄长度、小叶长度、小叶宽度、茸毛、耐旱性和耐热性是野生草莓遗传性状的主要指标,茸毛数量与抗逆性密切相关。
The species and geographical distribution of wild strawberry resources in Sichuan and its surrounding areas (excluding Qinghai Province) were investigated. The collected wild strawberry resources were ex-situ preserved, and their agronomic traits, abilities to resist abiotic and biotic stress were studied Component Analysis. The results showed that the wild strawberry in the high altitude area around Sichuan and its adjacent areas mainly distributed in the vertical space of 26 ° 14 ’~ 33 ° 22’N, 96 ° 57’ ~ 108 ° 13’E and elevation 823 ~ 4531m. Fragaria nilgerrensis Schlecht, F. pentaphylla Lozinsk., F. moupinensis (Franch.) Card. And F.gracilis Lozinsk. Are the four Wild strawberry species, of which five-leaf strawberry has two types of red and white ginkgo. Ruddy berry berries have a special peach aroma. Plant height, petiole length, leaflet length, leaflet width, velvet hair, drought tolerance and heat tolerance were the main indicators of the genetic traits of wild strawberry. The number of anthers was closely related to stress resistance.
