2、行回歸分析,并與其父本9147、母本云煙85做比較。結(jié)果表明:(1)云煙99及其親本3個(gè)性狀共9個(gè)Lo-gistic生長模型方程擬合程度均達(dá)極顯著水平,能較真實(shí)地反映云煙99及其親本的生長特性;(2)云煙99株高比親本略高,葉片數(shù)與親本相當(dāng),中部葉葉面積與父本相當(dāng)、比母本大;(3)云煙99株高和葉片數(shù)的線性生長期與父本相當(dāng)、比母本長,中部葉葉面積比親本長;(4)云煙99的3個(gè)性狀平均生長速率均介于雙親之間,但線性生長速率和最大生長速率存在差異。關(guān)鍵詞:烤煙新品種;云煙99;生長特性;Logistic;回歸分析中圖分類號(hào):S572文獻(xiàn)標(biāo)志碼:A文章編號(hào):1000-2286
