为了提高晒晾烟种质的育种利用价值，以马里兰烟、TN90、湄潭大蛮烟、巴斯玛、青梗和永胜晒烟为父本（P1）与6个烤烟品种K326、Va116、NC82、G70、红花大金元、H80A 270-2为母本（P2），按 NC Ⅱ设计组配成36个杂交组合，探讨质体色素的杂种优势表现，并对各亲本自交系的一般配合力和组合的特殊配合力进行分析。结果表明：1）6个晒晾烟品种中，除类胡萝卜素外，其余质体色素含量的一般配合力方差均达到显著差异，即存在显著的加性效应；6个烤烟品种一般配合力方差不显著；组合的特殊配合力方差达极显著或显著水平，即各组合基因型效应同时受加性和非加性效应影响。2）杂种优势因性状及杂交组合的不同呈现出较大的差异，4个性状群体平均优势大小顺序为叶绿素 b＞总叶绿素＞叶绿素 a＞类胡萝卜素，群体超亲优势除类胡萝卜素外均表现为正向。综合各个性状的杂种优势和配合力来看，红大×TN90、G70×TN90、Va116×湄潭大蛮烟是较好的组合，Va116、G70、TN90及巴斯玛是较好的亲本。

In order to further strengthen the value of sun-cured tobacco germplasm breeding,six tobacco varieties (Maryland、TN90、Meitan big smoke、Basma、Qinggeng and sun-cured Yongsheng)and six inbred varieties (K326、Va116、NC82、G70、big red、H80A 270-2)hanging out smoke,designed by NC Ⅱgroup dubbed 3 6 hybrid combinations.The plastid pigment heterosis was explored,while each inbred lines of GCA and SCA portfolio were analyzed.Results:1 )Six varieties of tobacco hanging out GCA,the plastid pigments (carotenoids except outside)of the GCA variance were significant differences,there were significant differences in additive effects.In the six flue-cured tobacco varieties in the GCA variance was not significant;combination of SCA variance was highly significant or significant,the combined effect of genotype kept by both additive and non-additive effects.2)Heterosis hybrids existed different characters and showed a big difference,the order of four traits population was:chlorophyll b> total chlorophyll>chlorophyll a > carotenoid group. Hpb outside except carotenoids were expressed as positive. Comprehensive various traits Heterosis and Combining ability of view,big red × TN90、G70 × TN90、Va116 × Meitan big smoke were pretty good combination;Va116、G70、TN90 and Basma were the better parent.
