对 10份不同遗传型香料烟的农艺性状、产量、产值、品质性状、光合特性等性状进行比较分析 ,结果表明 :沙姆逊× TOY和沙姆逊× Argjro两个杂种一代的综合性状表现明显地优于对照沙姆逊 ;香料烟杂种的优势既有正的又有负的 ,因不同组合而异 ;以沙姆逊作为母本的杂种一代在一些性状上优于相应的反交组合 ;不同遗传型香料烟在生长不同时期的光合速率、蒸腾速率存在较大的差异。对于吃味型香料烟 ,杂种一代的利用作为新品种选育的途径之一具有较大的潜力 The agronomic traits, yield, yield, quality traits, photosynthetic characteristics and other traits of 10 different genetic tobacco varieties were compared and analyzed. The results showed that the comprehensive traits of Sharmson × TOY and Shamirong × Argjro hybrids were significantly Superior to the control of Sham Hsun; the advantages of aromatic tobacco hybrids both positive and negative, due to different combinations; hybrids with Shamsun as the female parent in some traits than the corresponding anti-crossing combinations; different The photosynthetic rate and transpiration rate of genetic tobacco were different at different growth stages. For the taste-type aromatic tobacco, the use of hybrid generation as a new breed of breeding methods has greater potential
