Assessment of potential winter hardiness in winter bread wheat cultivars and genotypes by analyzing autofluorescence in seedling tissues
نویسندگان
چکیده
Background.Winter crops are the most productive component of agricultural biocenoses. In Russia, winter wheat suffers greatest losses in winter, so a search for traits marking high or low hardiness autumn-sown genotypes, including improved cultivars, is needed to assess their potential overwintering. One such markers an increased lignin content plant tissues. The terminal enzyme phenylpropanoid pathway metabolism, wherein components formed, cinnamyl-alcohol dehydrogenase (CAD, EC 1.1.1.195). plants, CAD one links aromatic which generates, addition lignin, number compounds, as lignans, glycosides, etc. Many these like contain chromophore groups and capable autofluorescence. Correlations genotypes that incorporate CAD1-F with overwintering studied this work. Materials methods.The bread cultivars ‘Zitnica’ (Yugoslavia) ‘Novosibirskaya 9’ (ICG SB RAS, Russia), contrasting isozyme spectra, hybrids, 28 developed Krasnodar were selected study. Fluorescence analysis was also performed. Correlation coefficients between fluorescence frost tolerance calculated using results 7 cultivars. Conclusions. tested demonstrated interplay successful overwintering: correlation found carrying 00 allele higher percentage overwintered plants. This dependence not observed every season. seedling sections can be used preliminary assessment under laboratory conditions.
