New methods in genotype diagnostics of small-fruit crops for intensive gardening

Abstract

Physiological and morphological studies of red Russian and foreign breeding red currant varieties were carried out for establishing intensive plantings and introduction. Varieties Dana, Niva, Vika, Hollandische Rote are yielding, highly resistant and promising for introduction and industrial cultivation, during dry periods they are able to regulate metabolism through changing indicators of water balance (water deficit, fractional composition of water) and photosynthetic apparatus of leaves (leaf lamina area). Using Natali, Shchedraya and Jonkheer Van Tets varieties in production is possible with application of artificial irrigation. Selyanochka variety is most affected by weather conditions and is recommended to be grown in temperate climate area. Physiological and morphological methods of research allow to diagnose the genotypes resistance of garden crops to growing period abiotic factors at the early stages of plant development, they are confirmed by field observations and are promising in diagnosis for establishing intensive gardens and berry-fields.
