摘要
[目的]为了给甜菜新品种选育提供亲本材料和基础材料.[方法]通过对引进及自育甜菜种质资源材料杂交后代进行育性、胚数性、产量、含糖率、配合力、细胞质类型、细胞核基因型、花粉粒细胞形态等性状鉴定选择,历经 9 年 5 个世代,选育出了优良甜菜单胚雄性不育系及保持系.[结果]单胚雄性不育系'NM 3006A'的不育率为 100%,单胚株率为 100%,花药发育形状不规则且干瘪,花粉粒表面黏稠且不光滑,细胞质类型为S型,细胞核基因型为xxzz.单胚雄性不育保持系'NM 3006B'的可育株率为100%,单胚株率为 100%,花药发育形状规则且药室饱满,花粉粒为圆球形且表面光滑,细胞质类型为 N1 型,细胞核基因型为 xxzz.[结论]甜菜单胚雄性不育系'NM 3006A'及保持系'NM 3006B'为糖用型二倍体单胚雄性不育系及保持系,2023 年 7 月通过国家甜菜专家鉴定组鉴定,达到成系标准并命名,该不育系属于偏高糖型、配合力较高的不育系.
Abstract
[Objective]To provide parental materials and basic materials for breeding new varieties for sugar beet.[Methods]Through identification and selection of traits such as fertility,embryo number,yield,sugar content,combining ability,cytoplasmic type,nuclear genotype,pollen grain cell morphology,etc.in the hybrid offspring of introduced and domestic developed sugar beet germplasm resources,after 9 years and 5 generations,excellent sugar beet monogerm male sterile lines and maintenance lines were developed.[Results]The sterility rate of the monogerm male sterile line'NM 3006A'is 100%,and the monogerm plant rate is 100%.The anther development shape is irregular and shriveled,the surface of the pollen grains is sticky and not smooth,the cytoplasm type is S type,and the nucleus genotype is xxzz.The fertile plant rate of the monogerm male sterile maintenance line'NM 3006B'is 100%,the monogerm plant rate is 100%,the anther development shape is regular and the anther chamber is full,the pollen grains are spherical and smooth on the surface,the cytoplasmic type is N1,and the nucleus genotype is xxzz.[Conclusion]The monogerm male sterile line'NM 3006A'and the maintainer line'NM 3006B'were diploid monogerm male sterile line and maintainer line used for sugar production.In July 2023,they were identified by the national sugar beet expert identification group and met the standard for line formation and were named.This sterile line belongs to the high sugar type and has high combining ability.
