两个葡萄杂交后代根系抗葡萄根瘤蚜及抗寒性鉴定
Evaluation on phylloxera resistance and cold hardiness of roots of two grape hybrid combinations
摘要
Abstract
[Aim] To screen cold-tolerant and phylloxera (Daktulosphaira vitifoliae Fitch)-resistant grape rootstocks for grapevine industry.[Methods] Laboratory bioassays were conducted on 45 strains (series A) of hybrid combination Vitis amurensis Rupr.Zuoshan No.1 × SO4 and 27 strains (series B) of hybrid combination V.amurensis Rupr.Zuoshan No.1 × 101-1 to evaluate their resistance classes to phylloxera.A system of differential thermal analysis (DTA) was used for low temperature exotherms (LTE) analysis of roots of these strains,and the temperature-injury (LT-I) regression functions were established to evaluate the cold hardiness of roots.[Results] Phylloxera produced less eggs on these hybrid strains than on the susceptible strain Kyoho,and 18 strains from series A and 11 strains from series B with no tuberosities were classified with the resistance class 0,and nine varieties from series A and four varieties from series B with less than 10％ tuberosities were classified with the resistance class 1.Twenty-seven strains from series A and three strains from series B,whose root,phloem and xylem subordination values were all lower than those of Beta,were selected for phylloxera resistance comparison.[Conclusion] In this study 15 strains from series A and 2 strains from series B with high phylloxera resistance and cold hardiness were selected,and the resistance class of A14,A16,A18,A22,A23,A28,A34,A35,A38,A44,A50,B24 and B26 was 0,and that of All,A15,A17 and A27 was 1.关键词
