The history of department of genetic, breed¬ing and seed-growing is linked with the develop¬ment of agronomic faculty of Kuban Agricultural Institute. There was shown the role of S.S. Zamotaylov - the sixth head of the department, scientist-geneticist, specialist in cytology, embryology, experimental haploidy, practical selection and V.V. Efremova- the seventh head of the department, well-known teacher in genetics, selection, seed-growing and variety breeding of field crops as well

There were considered the morphological traits and biological peculiarities of rice which should be taken into account at this plant cultivation working out with the aim of getting of maximally high yield at excellent grain quality. There were marked the rice varieties for different conditions of growing

Among fungus diseases of rice, blast is the most harm-ful. The disease is caused by Pyricularia oryzae Cav. Rice is sensitive to blast at all fazes of vegetation. In Russia, the purposeful breeding of rice varieties re-sistant to this disease began in 1982. Over the past period, the rice varieties which are genetically protect-ed from blast and not requiring crop protection have been created

Future increase of rice productivity is possible in expense of plant change architectonics. Creation of plants with erect position of leaves allows to compact sowings and to increase the productivity of cenosis. There were studied the rice samples with erect leaves and large grain as an initial material for selection on increased productivity

In this article results of research of quality characteristics of Russian and foreign rice varieties are observed. Possibility of using data in characterizing germplasm from collection is discussed

Under conditions of vegetation experiment at soil artificial chloride salinization the dynamics of accumulation and distribution of sodium, potassium and calcium in organs of rice plants (Oryza sativa L.) have been studied, as well as their correlation with tissue hydration in ontogenesis. The significant restriction of salinization ions transport and accumulation, particularly sodium, in the actively functioning upper leaves and panicles has been observed. Whereas the content of calcium and potassium in the experimental and control plants differed slightly

The anthers of glutinous rice variety Violetta (1400) have been grown in medium N6 producing 72 calluses. Transplanting the calluses to regeneration medium MS gave 7 green fertile plants and one sterile. After 10 months the long cultivated calluses of the glutinous rice Violetta produced regenerated plants. They were passed onto MS medium containing 5 mg/l 6-benzylaminopurine and 1 mg/l IAA. Clonal reproduction was used for production of more haploid regenerated plants

In this article the results of the research of quality characteristics of Russian and foreign rice varietieswere observed. A possibility of using the data in characterizing germplasm from the collection was discussed

There was studied the influence of factors of the medium on rice plants and hybrids of the first generation in the vegetation experience on the conditions of the artificial climate camera (ACC) and on the vegetation plot (control). There was determined the individual reaction of varieties on the conditions in ACC. There were revealed the modified changes at rice plants by a range of features. There was made a conclusion on necessity of preliminary study of varieties in ACC before their introduction into hybridization

In this article, the results of the research of quality characteristics of Russian rice varieties were observed
