基于SSR标记的象草F1代杂种分子鉴定及表型变异分析
Identification of hybrids and analysis of phenotypic variation in the F1 generation of Pennisetum purpureum based on SSR markers
采用传统杂交方法,以象草品种“GM1”为母本、新品系“F-B”为父本进行杂交,获得536个杂种后代,并从中选取150个有代表性的F1代株系群体进行变异分析。本研究结合表型性状和SSR分子标记,对这些后代进行杂种鉴定及表型变异分析,旨在为象草种质创新和品种改良提供技术支撑。结果表明:1)F1代群体较亲本表型变异丰富,其中叶长明显强于亲本,具有明显的杂种优势,性状存在显著差异,变异系数为5.90%~21.05%;2)筛选出的14对SSR引物共扩增得到219条清晰条带,其中多态性条带118条,多态性比率(PPB)54.18%;每个SSR位点的多态信息含量(PIC)为29.59%~44.63%,均值为35.40%;3)对亲本及杂交F1代进行聚类分析可知,基于表型数据的聚类分析将杂交后代分为3类;基于SSR分子标记的聚类分析将杂交后代分为4类,SSR分子标记进一步证实了母本在遗传上的主导地位;4)利用特异性引物可以准确鉴定出真杂种,鉴定率高达98%,大部分真杂种条带为双亲互补型,部分为父本型,表明F1代中存在父母本的遗传信息。通过对150个F1代株系群体的表型性状和筛选出的15对SSR核心引物分析,能有效鉴定杂种的真实性,为后续杂交育种选育新品系提供后备材料。
In plant breeding, it is important to generate hybrids with sufficient phenotypic variation for germplasm innovation and variety improvement. In this study, we used the traditional hybridization method to cross Pennisetum purpureum ‘GM1’ (female parent) with the new line ‘F-B’ (male parent), producing 536 hybrid offspring. We selected 150 representative F1 lines for variation analysis, and performed hybrid identification and phenotypic variation analysis based on phenotypic traits and simple sequence repeat (SSR) markers. The main findings were as follows: 1) The F1 generation showed greater phenotypic variation than the parents. Leaf length exhibited significant hybrid vigor and trait differences, with variation coefficients of 5.90%-21.05%; 2) Fourteen selected SSR primers amplified 219 clear bands, of which 118 were polymorphic, representing a polymorphism rate of 54.18%. The polymorphism information content value for SSR loci ranged from 29.59% to 44.63% (mean 35.40%); 3) A cluster analysis based on phenotypic data grouped the hybrids into three categories, while SSR-based analysis divided them into four. The SSR-based analysis confirmed the maternal parent’s genetic dominance; 4) Specific primers accurately identified true hybrids with a 98% success rate. Most true hybrids had complementary parental bands, and some were the paternal-type. These results show that SSR analysis can reveal parental genetic information for the F1 generation. Analyses based on phenotypic traits and 15 SSR core primers were able to effectively identify authentic hybrids among 150 F1 hybrid progenies, highlighting materials that will be suitable for breeding new lines.
