Correlation analysis of traits characterizing the yield and product quality of representatives of the genus Allium (subgenus Cepa)

Abstract

In the conditions of the Moscow region, 10 samples of representatives of the genus Allium L. were studied, including: A. altaicum Pall., A. fi stulosum L., A. galanthum Kar. & Kir., A. oschaninii O. Fedtsch., A. pskemense B. Fedtsch from the section Cepa (Mill.) Prokh.; A. altyncolicum N. Friesen, A. ledebourianumSchult. & Schult. f., A. oliganthum Kar. & Kir., A. schoenoprasum L. from the section Schoenoprasum Dum.; A. komarovianum Vved. from the section Sacculiferum P. P. Gritz. The presented study is planned to determine the correlation between various traits that contribute to an increase in yield and the accumulation of biologically active compounds in leaves. These samples analyzed morphological characteristics (plant height, number of leaves per plant, number of shoots per plant, leaf length, leaf width and total leaf yield) and biochemical parameters (dry matter, nitrates, ascorbic acid, monosaccharides, chlorophyll, carotene, fl avanoids, hydroxycinnamic acids). Analysis of variance showed signifi cant diff erences between the tested genotypes for all studied parameters, namely phenotypic, biochemical and yield traits. The relationship between the parameters was assessed using the Pearson coeffi cient. A close positive relationship was found between the number of shoots and the number of leaves per plant (0.964), leaf width and total yield (0.818), chlorophyll content and total yield (0.608), chlorophyll and carotene content (0.841), leaf length and hydroxycinnamic acid content (0.859), dry matter content and ascorbic acid (0.756). The revealed patterns are of interest for constructing a model of varieties and use in breeding.
