AbstractInsect pollinators shape rapid phenotypic evolution of traits related to floral attractiveness and plant reproductive success. However, the underlying genomic changes and their impact on standing genetic variation remain largely unknown despite their importance in predicting adaptive responses in nature or in crop’s artificial selection. Here, based on a previous, nine generation experimental evolution study with fast cycling Brassica rapa plants adapting to bumblebees, we document genomic evolution associated to the adaptive process. We performed a genomic scan of the allele frequency changes along the genome and estimated the nucleotide diversity and genomic variance changes. We detected signature of selection associated with rapid changes in allelic frequencies on multiple loci. During experimental evolution, we detected an increase in overall genomic variance, whereas for loci under selection, a reduced variance was apparent in both replicates suggesting a parallel evolution. Our study highlights the polygenic nature of short-term pollinator adaptation and the importance of a such genetic architecture in the maintenance of genomic variance during strong natural selection by biotic factors.

В течение трех лет изучали 34 реципрокных гибрида, полученные при гибридизации 17 родительских пар между подвидами вида Brassica rapa. Анализировали содержание сухих веществ, белка, сахаров, аскорбиновой кислоты, общей кислотности, пигментов (хлорофиллы A и B, каротиноиды, каротины, β-каротин), нитратов. Показано, что все изученные гибриды пекинской, китайской, розеточной и японской капуст могут быть источниками высокого содержания аскорбиновой кислоты. В свою очередь, источниками высокого содержания хлорофиллов и β-каротина являются темно-зеленые образцы розеточной и японской капуст.

The study aimed to determine the effect of the combination of city waste compost and cattle manure on the growth and yield of pakcoy plants (Brassica rapa, L. Chinensis) in Aluvial, Indramayu Regency. The study was conducted at the Experimental Garden of the Faculty of Agriculture, Wiralodra University, Indramayu Regency from March to August 2018. This study used Factorial Pattern Randomized Block Design with two factors. The first factor is city waste compost and the second factor is cattle manure with 4 levels: 0%, 3.0%, 6.0%, and 9.0%, repeated twice. The results showed that there was an independent influence between city waste compost and cattle manure on plant height and number of leaves. The best combination to increase the feasibility weight of pakcoy consumption is by giving city waste compost 9.0% (S4) and cattle manure 6.0% (K3).
