Growth Characteristics of New Flue-cured Tobacco Variety Yunyan99 and Its Parents
摘要
Abstract
In order to study the growth characteristics of a new flue - cured tobacco variety Yunyan99, lo-gistic regression analysis was performed to analyze the data of plant height, leaf number and middle leaf area of the Yunyan99,9147 ( ♂ ) and Yunyan85 ( ♀ ). The results showed that; ( 1 ) goodness-of-fit of nine logistic models established from the three characters of the three flue-cured tobacco varieties reached extremely remarkable level. Nine models could truely reflect the growth characteristics of Yunyan99 and its parents, (2) the plant height of Yunyan99 was higher than that of its parents, but the leaf number was not significantly different from that of its parents, the middle leaf area was equal to that of its female parent and larger than that of its male parent; ( 3 ) the linear growth days ( LGD ) of Yunyan99 ' s plant height and leaf number were equal to those of its male parent and longer than those of its female parent, LGDs of the middle leaf area were more than those of its parents. (4) The average growth rates (AGR) of the three characters of Yunyan99 were between those of 9147 and Yunyan85,but the linear growth rate(LGR) and the maximum growth rate(MGR) were different.关键词
