Fonio production is generally in polyvarietal mixture and no improved varieties are available yet. This work proposed a pathway for homogenization and mass selection from 19 accessions previously collected in Benin, to sort best genotypes. From 2015 to 2017, accessions were submitted to homogenization followed by separated conduct of different phenotypes appeared each year. Each material was evaluated on elementary plot of 3 m². Agro‐morphological data collected were submitted to descriptive and multivariate analyses. Results showed homogeneity and selection effectiveness varied following characters and accessions. Better homogeneity level was obtained on qualitative characters compared to morphometric traits. Selection led to derivative accessions earlier or more productive than their parents. Thus, compared to parents, shortenings of 10%–30% on plant cycle and progress of 10%–70% in yield were recorded for some derivative accessions. On grains colour, 86% of accessions are homogeneous from 70% to 100%. Three groups characterized by earliness, productivity and grains homogeneity were identified. AS19‐1‐1, AS1, AS13‐1, AS2‐1‐1, AS15‐1‐1 and AS18 were sorted genotypes. Multi‐local assessments will be conducted for homogeneous and efficient ideotypes responding farmer's needs.

贝宁种植的火地黄（Digitaria exilis）的大规模选择：途径，同质性评估和基因型筛选

Fonio生产通常以多品种混合物的形式存在，尚无改良品种。这项工作提出了从贝宁以前收集的19个种质中进行均质化和质量选择的途径，以对最佳基因型进行分类。从2015年至2017年，每年均对种质进行均质处理，然后分别进行不同表型的分离。在3 m ^2的基本图中评估每种材料。收集的农业形态数据已提交描述性和多元分析。结果表明，同质性和选择效率随性状和种质而变化。与形态特征相比，在定性特征上获得了更好的同质性水平。选择导致派生的加入比其父母更早或更富有成效。因此，与亲本相比，某些衍生品录得的植株周期缩短了10％–30％，产量提高了10％–70％。在谷物颜色上，从70％到100％，86％的种质是均匀的。确定了以早期，生产力和谷物均一性为特征的三个组。AS19-1-1，AS1，AS13-1，AS2-1-1，AS15-1和AS18是分类基因型。将针对农民的同质和有效意识形态进行多地区评估
