核果类芽变品种调查及存在的问题

Investigation and Existing Problems of Drupe Bud Mutation Cultivar

在查阅《园艺学报》等国内期刊及互联网20余a的核果类果树芽变品种文献基础上,统计比较了各种果树芽变品种数量和人工诱变品种数量,以期分析芽变选种存在的问题,并结合实际工作,提出了解决和改进建议。结果表明:国内外共查出6种核果已选育出芽变品种65个,国内总共人工诱变品种仅3例,其余都是自然芽变;芽变选种存在工作重视不够、多数未列入育种方案、尚未提出选择淘汰劣变的问题、热衷于一些高深层面的亲缘鉴别课题、关注诱变方式方法较少等问题。

Based on Mutant varieties of fruit trees through research and display, for reference, Analyzed of mutant selection problems, discussed ways to solve the problem, the purpose was bringing out more good mutant varieties. Searched ＂Horticulture Technology＂ and other publications, collected all of these publications online of nearly 20 years of mutant varieties of stone fruit literature, to distinguish between types of parental source characteristics of focus variation. Compared statistics of fruit trees and artificial mutant of varieties to analysis the root causes of some of the problems a small number, combined with practical work,The was to improve solution method. The results showed that 6 stone fruit at home and abroad were found to have been selected mutant varieties 65. Only 3 artificial mutation cases of total domestic varieties,the rest were natural mutant. The problems identified, inadequate attention to the work of mutant selection. Most breeding programs were not included. Not yet eliminated the problem of deterioration. Interested in genetic identification of issues. Less attention to the improvement of mutation. Raise awareness of the importance of work in mutant selection.
