ABOUT ASSOCIATIVITY BETWEEN SUSCEPTIBILITY TO LETTUCE MOSAIC VIRUS AND LEAF FORM IN LETTUCE FROM THE VIR GENORESOURCE WORLD COLLECTION

N.N. Grin’ko

For the first time in the conditions of damp subtropics of Russia on the basis of ecological estimating the leaf form of lettuce plants the author demonstrates the associativity between susceptibility to Lettuce mosaic virus and phenotypic features of plants. The genotypes of lettuce were isolated, which are of practical interest as initial material for immunity breeding programs and for widening of food crops assortment.

Keywords: gene resources, salad (Lactuca sativa L.), yellow mosaic virus (Lettuce mosaic virus), stability sources, phenotypes signs.
