| 摘 要： | 本文对分别含有 Tm-1、Tm-2~(nv)、Tm-2~α的三个抗 TMV 病毒基因的品种强力米寿、矮黄、Ohio MR-9和以这三个抗原为亲本配制的 F_1代进行了抗病性鉴定,并对其八个主要性状配合力进行了分析,从而确定了三个抗原的实用价值。结果表明,三个抗原材料和 F_1代对 TMV 病毒都表现出一定的抗性,尤其是含有 Tm-2~(nv)和 Tm-2~α基因的 F_1代及亲本有高度抗性。同时,三个抗原材料配合力均高,在绝大多数组合中前期产量和总产量皆有明显的竞争优势。特别矮黄在八个性状中除单重外,一般配合力效应值都很高,可能与 nv 基因的多效作用有关。所以,矮黄是一个比较优良的杂交亲本。另外,本文对三个抗原八个性状的遗传参数也进行了估算,并选出了抗 TMV 病毒早熟丰产组合:矮黄×汉因兹、矮黄×加八号等。

UTILIZATION OF THREE TMV-RESISTANT VARIETIES OF TOMATO AND THE ANALYSIS OF THEIR HEREDITARY CHARACTERS |

| Abstract: | This paper deals with three varieties of ‘Qiang Li Mi Show’,‘DwarfYellow’and‘Ohio MR-9’which contain TMV-rasistant genes of T_(m-1),T_(m-2)and T_(m-2)~a respectively.These three varieties were used as female parents forhybridization.The virus-resistance of the first generation was identified and thecombining ability of eight principal characters was analyzed.Thus the practialvalue of the three antigen plants was defined.The results indicated that the antigen plants and the hybrids of first genera-tion all manifested virus-resistance at a definite level,especially the parent andthe F_1 hybrids which contained T_(m-2)~(nv) or T_(m-2)~a gene.Meanwhile,these three an-tigen plants possessed higher combining ability,a clear superiority of competitionboth in early and in total yields was exprassed in most hybrid combinations.Especially‘Dwarf Yellow’possessed very high combining ability in the eightcharacters except average weight per fruit.Hence‘Dwarf Yellow’is a betterparent for hybridization.In addition,hereditary parameters of the eight characters of the threeantigen plants were estimated,and a fine hybrid combination virus-resistanceand early high yield combining was selected. |
