ANALYSIS OF SYNANTHROPIC FLORA OF RICE SYSTEMS OF THE KRASNODAR REGION

abstract 0931309008 issue 93 pp. 108 – 123 30.11.2013 ru 1601
This article has given the analysis of systematic and ecological structures of synanthropic flora of rice sys-tems of the Krasnodar region. There was shown the relation of plants of aboriginal and adventive frac-tions of flora to different ecological factors. There were studied the timeness of different plant species to elements of the rice system and the degree dependence of their distribution on rice growing tech-nology

ECOLOGICAL AND BIOLOGICAL BASES OF THE RICE VARIETY LIDER GROWING ON PESTICIDE-FREE TECHNOLOGY

abstract 0711107006 issue 71 pp. 70 – 80 30.09.2011 ru 1600
As a result of stepped hybridization and multiple replicated screening, the new rice variety Lider was received. The peculiarities of the new variety is a quick growth of plants at a sprouting – tillering stage. It gives the possibility to obtain sprouts from water lower than 20-25 cm which kills for Echinochloa. Lider is grown in Russia without application of pesticides.

NEW ADVENTIVE WEED PLANT AMMANNIA COCCINEA Rottb. IN THE RICE FIELDS OF THE KRASNODAR REGION

abstract 1311707130 issue 131 pp. 1587 – 1601 29.09.2017 ru 437
Rice fields all over the world are one of the places of invasion of adventive weed species. They can reduce the yield of the rice crop by 20-30%. The phytomonitoring studies in the rice systems of the Krasnodar region in 2017 have discovered a new species of Ammannia coccinea Rottb. (Lythraceae) among the weed vegetation of the grain crops. The article gives a botanical description of the species; its biological and ecological features and ways of its distribution are discussed. Ammannia coccinea is an annual plant, light-loving and hygrophilous. The country of origin is North America. This is one of the most malicious weeds in California and the United States in general. In Asian and European countries, the plant is brought with rice seeds. Currently, in many rice-growing regions of the world, the species A. coccinea tends to spread and increase the severity of infestation. The species was registered in the Krasnodar region in the rice fields of the Abinskiy, Kalininskiy, Krasnoarmeiskiy and Slavyanskiy regions. The number of plants of A. coccinea does not exceed one plant per 10 m2, with the exception of three locations of invasion, where the density is up to 5-7 pcs/m2 and the plants occupy an area about 0.5 hectares. Considering the fact that in rich soils the height of the plant reaches 1 m, with the ramification of the stem, the plants go to the first tier. They successfully compete with rice plants, suppressing their growth and development. This can adversely affect crop yield. The article discusses the reasons for the appearance of A. coccinea in the rice fields of the Krasnodar region

ON THE HYBRIDIZATION OF RICE VARIETIES AND WEED-FIELD RED GRAIN FORMS

abstract 1592005009 issue 159 pp. 133 – 146 29.05.2020 ru 170
Large areas under commercial rice in many countries of the world including Russia are infested with weed-field red grain forms of rice. In the nineties of the XX century new red grain forms of rice appeared in the rice commercial fields of the Krasnodar region; these plants differed little from the morphotype of the variety in morphological characteristics. Such plants were difficult to distinguish and remove during varietal weeding. The increased content of red rice grains among the elite seeds leads to the rejection of such crops, thus reducing the economic efficiency of the seed production. Researchers do not have a single opinion on the origin of the new forms of the red grain rice. Various assumptions are made on mutations, unlocking of epigene of the pericarp coloration of the caryopsis to return to the ancestral red grain forms, and cross-pollination between cultivated and red grain rice. In 2014-2018 a methodological experiment on artificial hybridization between the white grain variety and rice varieties with colored pericarp of the grains (Mars and Yuzhnaya Noch) was carried out to discover the origin of these new forms of the red grain rice. The article presents an analysis of hybrids of direct and reverse crosses between the white grain variety Snezhinka, having an amylose long grain, and the black grain variety Yuzhnaya Noch with a glutinous short grain. As a result of artificial hybridization, a new initial material was received with a different type of grain in shape, color and consistency of the endosperm. This material is of significant interest for further breeding and genetic research. When evaluating hybrid plants obtained by direct crossing Snezhinka / Yuzhnaya Noch and reverse crossing Yuzhnaya Noch / Snezhinka, a significant influence of the maternal cytoplasm on the formation of quality signs of endosperm has been revealed. This must be considered when planning such studies. An analysis of the economically valuable traits of the received hybrid material brings a conclusion that the new red grain forms in the commercial rice varieties may appear as a result of spontaneous hybridization between red grain and white grain rice

RUSSIAN RICE VARIETIES FOR CHILDREN’S AND CURATIVE NUTRITION

abstract 0721108001 issue 72 pp. 1 – 27 30.10.2011 ru 1643
There were described the rice varieties created in Russia for production of children’s and curative nutrition. Among them are waxy varieties as Viola and Violetta, long-grained – Snezhinka and Avstral and red-grained – Mars as well. There were cited the agro biological characteristics of these varieties

TEN YEARS THAT CHAGED THE BIOLOGICAL WORLD (FROM HISTORY OF GENETICS)

abstract 0631009011 issue 63 pp. 155 – 161 27.11.2010 ru 2044
A new science – genetics was born in the first decade of XX century. The part of G. Mendel as a founder of this science is showed here. Also here are scrutinized tasks of scientists - biologist, who assist to the making and progress of genetics
