Genetic diversity and agronomic performance of Slovenian landraces of proso millet (Panicum miliaceum L.)

Proso millet (Panicum miliaceum L.) has many favored nutritional and agronomic traits, which makes it appropriate forcultivation and consumption all around the world. Genomic resources for proso millet are still very limited but the set of genomic datais improving. In this study, we genotyped six Slovenian landraces of proso millet (P. miliaceum L.) along with one Slovene autochthonouscultivar, Sonček. The chosen set of 11 SSR markers showed that there is low overall heterozygosity (0.561) among Slovenian landracesof proso millet. However, we were able to determine distinct groups on the dendrogram for different landraces and the cultivar byusing UPGMA clustering. The PCoA scatter plot showed dispersion of unique individuals. The SSR markers used proved to be efficientfor assessing the genetic diversity of Slovenian landraces of proso millet. Furthermore, we performed a 3-year field experiment anddetermined grain yield (ranging from 1032 to 1667 kg ha−1) and yield stability using Kang’s yield stability index (YSi). The morphologyof panicles and grain was described as well.
