摘　　要：【目的】为了探明野生红肉猕猴桃新种质‘JXFX-CK-04137’和红肉猕猴桃品种‘红阳’的性状差异,【方法】通过生物学特性调查和体细胞染色体数目的观察,对‘JXFX-CK-04137’和‘红阳’的形态水平和细胞水平的遗传差异进行了检测。【结果】结果表明,‘JXFX-CK-04137’和‘红阳’的花、叶、果等生物学特性均存在显著差异,‘JXFX-CK-04137’的染色体为2n=4x=116,是四倍体;‘红阳’的染色体为2n=2x=58,是二倍体。【结论】研究揭示了‘FXJX-CK-04137’是一个新的红肉猕猴桃种质资源,为红肉猕猴桃育种提供了新的优良育种材料。【Objective】The objective of the study was to elucidate genetic variation of biological characteristics and chromosome ploidy between a new wild red-fleshed kiwifruit germplasm ＇FXJX-CK-04137＇ and the red-fleshed kiwifruit cultivar ＇Hongyang＇.【Method】Through the investigation of biological characteristics and somatic chromosome number observation,the genetic variation were evaluated.【Result】The results showed that there are genetic differences in biological character between ＇JXFX-CK-04137＇ and ＇Hongyang＇.The former is a tetraploid,2n=4x=116,while ＇Hongyang＇ is a diploid,2n=2x=58.【Conclusion】The studies revealed that ＇FXJX-CK-04137＇ is a new red-fleshed kiwifruit germplasm resources and could be used as breeding material.
