摘要: 为进一步了解杉木Cunninghamia lanceolata 种子品质遗传变异规律, 对浙江省22 个不同世代不同类型种子园, 连续4 a 采种、取样和测定, 系统地分析了种子千粒质量、涩籽率、发芽率、发芽指数、芽苗长度和活力指数等6 项品质性状的变异、遗传力和遗传相关。结果表明, 种子活力指数表型变异与遗传变异均最大, 涩籽率变异次之, 芽苗长度变异最小。种子千粒质量遗传力最大, 涩籽率次之, 其后依次为芽苗长度、发芽率、活力指数和发芽指数。千粒质量与各性状具有轻度和中度的遗传相关关系, 涩籽率在遗传上除与千粒质量呈轻度负相关外, 与其他性状没有相关关系, 发芽率与发芽指数以及发芽指数、芽苗长度与活力指数遗传相关紧密。表4 参12

Abstract: For knowing further about the genetic variation regularity of seed quality of Cunninghamia lanceolata , 22 seed orchards in different generations and different types were studied .After seed collecting , sampling , measuring for successive 4 years , the variation , heritability and genetic correlation of 6 quality characters , including thousand-grain weight , precentage of woody , germination percentage , germination index , seedling length , and vigor index were systemically analyzed .The results revealed that the level of phenetic and genetic variation of vigor index was the highest , that of sterile seed rate was the second , and that of seedling length was the lowest .Those seed quality characters from high to low in heritability order were as follows :thousand-grain weight , percentage of woody seed , seedling length , germination percentage , vigor index and germination index . There were light correlations between thousand-grain weight and other quality characters .There were light correlations between thousand-grain weight and other quality characters .There were no correlations between percentage of woody seed in heredity and others , except thousand-grain weight which relationship is lightly negatively correlated .But there were close correlations between germination percentoge and germination index , also between vigor index and germination index , seedling length .[ Ch , 4 tab .12 ref .]
