Dataset for: Evaluation of reproductive traits and pheno-genotypic analysis of self-compatibility in F1 population (CWR_LB)

"A total of 1203 genotypes from 38 segregant families (CWR_LB), obtained through crosses between potato wild relatives and 2x-hybrids with self-compatibility attributes, were assessed to investigate reproductive traits. The evaluation encompassed parameters such as flowering degree, peak flowering, pollen viability, and pollen 2n production. Concurrently, a crossing plan for the self-compatibility assay was implemented, involving two repetitions for each genotype. All crossing assay genotypes were collected and genotyped for Sli gene presence through the KASP platform to explore the correlation between phenotype and genotype. Ultimately, 336 genotypes exhibited phenotypic self-compatibility, yielding between 2 and 4000 true potato seeds (TPS). This output corresponds to the first self-generation cycle (S1)."

本研究对38个分离群体（CWR_LB）的1203份基因型材料开展繁殖性状评估，该群体由马铃薯野生近缘种与携带自交亲和特性的二倍体杂交种杂交获得。评估指标涵盖开花程度、盛花期、花粉活力及花粉2n配子产量。与此同时，为开展自交亲和性检测，本研究制定了杂交实验方案，每份基因型材料设置两次生物学重复。本研究收集了所有杂交检测用基因型材料，并通过KASP平台对Sli基因的携带情况进行基因分型，以探究表型与基因型之间的关联。最终，共计336份基因型材料表现出表型自交亲和性，可产生2~4000粒马铃薯实生种子（TPS），该实验结果对应首个自交世代循环（S1）。
