1 998～ 1 999年从巴西 Profigen公司引进的 1 2个烤烟品种 ,经过云南出入境检验检疫局室内检疫和隔离种植 ,没有发现烟草霜霉病 ,2 0 0 0～ 2 0 0 1年以 K32 6为对照进行田间引种观察试验和抗病性鉴定 ,设云南和贵州两个点。两年的试验结果表明 ,1 2个新品种的生育期与对照 K32 6基本相近 ,除了RGH1 2、RGH5 1、NC5 5和 K2 36感 TMV 外 ,其它品种抗TMV。各新品种都抗黑胫病 ,对照 K32 6中抗黑胫病。 RGH5 1中抗南方根结线虫病 ,K32 6抗 ,其它品种都感南方根结线虫病。 NC5 5中感青枯病 ,其它品种中抗青枯病。各品种都感赤星病。综合各经济性状来看 ,PVH0 9、RGH0 4、RGH5 1、PVH0 3、PVH0 1表现较好 ,PVH0 6、PVH0 5、NC5 5、PVH0 7等表现中等 ,PVH0 8和 K32 6表现较差
Between 1998 and 1999, 12 varieties of flue-cured tobacco introduced from Profigen Company in Brazil were found to have no downy mildew in tobacco after being quarantined and isolated by Yunnan Entry-Exit Inspection and Quarantine Bureau. In 2000-2002, K32 6 for the control of field introduction observation test and disease resistance identification, located in Yunnan and Guizhou two points. The results of the two years showed that the growth of 12 new varieties was almost similar to that of the control K32 6 except for TMV of RGH1 2, RGH5 1, NC5 5 and K2 36. All new varieties are resistant to black shank disease, control K32 6 anti-shank disease. RGH5 1 resistant to southern root knot nematode disease, K32 6 resistance, other varieties are susceptible to southern root knot nematode disease. Bacterial wilt in NC5 5 and resistance to bacterial wilt in other varieties. All varieties are brown spots. According to the economic traits, PVH0 9, RGH0 4, RGH5 1, PVH0 3 and PVH0 1 perform better, while PVH0 6, PVH0 5, NC5 5 and PVH0 7 are medium, while PVH0 8 and K32 6 perform poorly
