果树育种工作普遍存在的问题是结果迟,占地大,很多不能自交,故绝大多数果树皆为杂合体。因此,进行果树花药培养就具有更大的理论和实践意义。然而,到目前为止,尚未见到利用花药培养出单倍体果树植株的报导。对于葡萄这一温带广泛栽培的果树,格瑞霍夫(Gresshof 1974)曾报导了由栽培葡萄品种花药培养出单倍体愈伤组织;平林等培养野萄萄花药从中分化出枝,未移栽成活,新关宏夫(1976)在报告中讲它是一个二倍体;邹昌杰等报导经过几年转移数千块愈伤组织均未分化成茁。因此进行葡萄花药培养研究就十
The common problem of fruit tree breeding work is the late result, large area, many can not be self-made, so the vast majority of fruit trees are all hybrids. Therefore, the fruit anther culture has a greater theoretical and practical significance. However, up to now, there have been no reports of anther culture of haploid fruit trees. For grapes, a temperate and widely cultivated fruit tree, Gresshof (1974) reported that haploid callus was cultured from anther of cultivated grape varieties; Survival, the new Guan Hongfu (1976) in the report that it is a diploid; Zou Changjie et al reported that after several years of transfer of thousands of calluses did not differentiate into Zhuo. Therefore, grape anther culture research on the ten
