摘要
为了进一步探明西藏野生油菜种质资源的多样性,通过对西藏野生白菜类型油菜和野生芥菜类型油菜共49份种质资源的子叶形态、苗期生长习性、伸长茎性状、苔茎叶性状、植株性状、花瓣类型、角果着生状态、果喙长度、角果密度、籽粒性状等多种表型形态进行了种植观察与分析,结果发现:西藏野生油菜的形态类型多种多样,不仅有着丰富的遗传多样性,而且与西藏林芝地区栽培油菜之间也存在着一定的关系;有些性状在西藏的油菜育种中有着潜在的利用价值。
In order to verify the diversity of the campestris rapeseed germplasm resources in Tibet, through to the Tibet wild cabbage type rapeseed and the wild leaf mustard type rapeseed altogether 49 idioplasm resources seed leaf shape, the seedling stage habit of growth, the elongation stem character, the liver moss stem leaf character, the adult plant character, the flower petal type, the silicle fresh condition, the fruit beak length, the silicle density, the grain character and so on many kinds of phenotype shape was carrying on the planter to observe and to analyze, finally discovered： Tibet wild rapeseed＇s shape type many and varied, not only has the rich heredity multiplicity, moreover also has certain relations with the Tibet Nyingchi area cultivation rapeseed between; Some characters have the latent use value in Tibet ＇s rapeseed breeding.
