Description
The search of resistance sources to the wheat stem rust pathogen among wheat collection material, its rare species and Aegilops (goat grass) was conducted. The samples resistant to the pathogen were detected. They have been studied on the artificial infectious background for three years and they are recommended for use in selection

INHERITANCE OF MORPHOLOGICAL CHARACTERISTICS FROM INTERSPECIFIC TOMATO F1 HYBRIDS
06.00.00 Agricultural sciences
DescriptionThe detailed morphological description of interspecific tomato F1 hybrids is represented in the article. The positive heterosis in regard to sire component was noticed in accordance with the following characteristics: fruit size, leaf size and stem length. It was established that the inclusion of tomato of Lycopersicon cheesmanii typicus genus into selection enables the obtaining of new species at the expense of increasing the range of genetic variability

Description
The article has covered the influence of the com-bined fungicide rex duo, suspension concentrate (310+87 g/l) on the population structure of wheat brown rust pathogen in the North Caucasus. The comparative assessment of effect of single-component preparations from different classes on the pathogen population was performed out

Description
Puccinia triticina isolates from North Caucasus and Leningrad region were compared in regard to the genetic structure, phenotypic composition as well as frequency of occurrence of RAPD-phenotypes and polymorphous major fragments with the help of Rogers index. Did not demonstrate any significant differences according to their genetic structure and occurrence of major fragments of DNA-polymorphism. The difference of isolates from given regions was determined with high degree of confidence according to the phenotypes of virulence and RAPD-phenotypes
