美国烤烟引种试验(第二批)简报

Brief report on introduction test of flue－cured tobacco varieties from USA （the second group）

按照中国烟叶生产购销公司的要求，对1995年从美国引进的一批烤烟品种安排了引种比较试验（第二批）。2000年分别在辽宁、黑龙江、山东、福建和云南5省进行，北方区以NC89为对照，南方区以K326为对照。结果表明，RG13、CU263和GL939在北方区均不同程度地优于对照；Speight G－168、CU263和RG13在南方区表现较好，低于对照K326，但差异不显著。

Comparative test was arranged for a set of flue－cured tobacco varieties, which were introduced from America in 1995． The introduction tests were carried out in Liaoning, Heilongjiang, Shandong, Fujian and Yunnan provinces respectively in 2000． The check variety was NC89 in the north and K326 in the south． The results indicated that RG13, CU263 and GL939 were all more or less superior to the control in the north; Speight G－168, CU263, RG13 and RG8 proved better though they were inferior to K326 in the south, and contrast with the check variety, the difference was not significant．
