电导法对32个辣椒品种组合抗寒性的测定及配合力分析
Determination and Combining Ability Analysis of Cold Resistance of 32 Combinations of Hot Peper Hybrid by Electric Conductivity
摘要
Abstract
In order to compare the cold resistance of the hot pepper varieties ,taking 32 combinations of hot pep-per hybrid as materials ,the relative electrical conductivity was deteriminated under low temperature in artificial climatic .The turning point temperature(semi-lethal temperature)was measured by Logistic equation and used as the index of cold-tolerance for all hybrid combinations ,the semi-lethal temperatures were compared .The re-sults showed that relative conductivity was increasing with the decrease of temperature ,change processing was in an S curve .The order of cold resistance of hot peppers was H2> H13≈ H28> H31≈ H1≈ H23> H24>H26> H30> H8> H27≈ H19> H5≈H12> H21> H3> H18> H15≈ H14> H22> H17> H7≈ H29> H4>H11> H10≈ H16> H20> H6> H9> H25> H32 .Combining ability analysis showed that the lowest GCA effect of relative conductivity was parent P1 and P2 ,the lowest SCA was P1 × P2 .关键词
