Heterosis and Combinging Ability of Yield among Key Parental Materials of Flue-cured Tobacco in Henan Province
摘要
Abstract
In order to study the yield genetic characteristics of flue-cured tobacco ,heterosis and combining ability were determined using seven key parental materials in this paper ,as well as their 42 F1 diallel crosses ,and relationships between F1 performance and its pedigree were investi-gated .The results showed that there were heterobeltiosis in yield among parents with the average value of 19 .2% ,and a large difference ranged from -7 .3% to 65 .6% among hybridized combina-tions .We screened combinations and found Zhongyan 100 × Qinyan 96 had the heterobeltiosis in yield of 65 .6% .Among these parents used above ,Qinyan 96 and 664-01 were elite .Heterosis of pods per plant and seeds per plant were relatively in accord with yield heterosis .And yield hetero-sis in parents was related to general combining ability (GCA ) and specific combining ability (SCA) .It was determined that at least one of parents had high GCA and both parents had high SCA in high-yield combinations .关键词
