Combining Ability and Degree of Heterosis in Sucker Producing Characteristices of Flue-cured Tobacco(Nicotiana tabacum L.)
황색종 연초의 곁순 발생에 대한 조합능력과 Heterosis 정도
Abstract
Seven flue-cured tobacco(Nicotiana tabacum) varieties and their 21 progenies in Fl and F2 generation, half diallel crosses(no reciprocal), were tested for the degree of heterosis and combining abilities in sucker producing character according to topping and suckering treatment. Significant difference in number and weight of sucker was observed among seven cultivars. The values of general combining ability(GCA) were greater than those of specific combining ability(SCA) in weight and number of sucker in F
