本研究发现1个具有雄性不育与单性结实特征的细胞核雄性不育系辣椒材料,并对该材料的农艺性状、单性结实坐果率、不同发育时期的不育系单性结实与可育系单性结实内源激素进行测定;利用田间鉴定和显微镜镜检,分析了F2群体的遗传分离情况,并利用辣椒细胞核雄性不育基因ms-3、msw、ms、msms、msc-1开发的分子标记,分析了群体的育性分离比。结果表明:不育系单性结实果实纵横径较大,可育系与不育系单性结实坐果率明显不同,可育系坐果率为22%,不育系坐果率为43%;不同时期不育系单性结实果实的赤霉素(GA4)含量显著高于可育系单性结实果实;田间鉴定和分子标记检测表明,F2群体中可育系有97株,不育系有30株,分离比为3.23∶1,符合孟德尔遗传规律,确定其育性由隐性单基因控制,将该辣椒细胞核雄性不育系命名为GMS702AB。本研究提供新的辣椒不育系,有助于辣椒育种和种子生产。
This study identified a nuclear male sterile pepper line showing male sterility and parthenocarpy characteristics, and the agronomic traits and parthenocarpy fruit setting rate of the material were determined, and the parthenocarpy of the sterile line at different developmental stages and the parthenocarpy of the fertile line were determined for endogenous hormones. In addition, the genetic segregation of F2 population was analyzed by field identification and microscopic examination, and the fertility segregation ratio of the population was analyzed by using the molecular markers developed by pepper nuclear male sterile genes ms-3, msw, ms, msms and msc-1.The results showed the vertical and horizontal diameters of the parthenocarpy fruit of the sterile line were larger, and the fruit setting rate of the fertile line and the sterile line was significantly different. The fruit setting rate of the fertile line was 22 %, and the fruit setting rate of the sterile line was 43%. The GA4 (gibberellin) content in the parthenocarpic fruit of the sterile line in different periods was significantly higher than that of the fertile line. There are 97 fertile lines and 30 sterile lines in the F2 population,with a separation ratio of 3.23 : 1,which is consistent with the Mendelian inheritance law. It showsd that its fertility was controlled by a recessive single gene. We named the nuclear male sterile line of pepper as GMS702AB. This study provides a new nuclear male sterile line valuable in pepper breeding and seed production.
