The genetic control of the day- neutral habit in populations of Fragaria vesca (Rosaceae) in Western Siberia. S. O. Baturin
Abstract: In Western Siberia, intense flowering of Fragaria vesca occurs in the first ten days of June and fruiting takes place from the end of June till early July. During our expeditions investigating natural Fragaria vesca L. populations of Western …
Inheritance of yellow colour in safflower (Carthamus tinctorius L.) T. V. Leus
Abstract: Safflower is a minor crop, and its genetics is poorly known. Four types of safflower corolla color are recognized: red, orange, yellow, and white. As the information on color inheritance is incomplete and contradictory, we aimed to study the …
Inheritance of cleistogamy in interspecific hybridization of Gossypium barbadense L. T. I. Mukhiddinov, A. A. Abdullayev, E. Kuchkarov, A. H. Choriev, S. K. Jumaev
Abstract: Studies of the inheritance and and variability of chasmo- and cleistogamous types of cotton flower on the base of intraspecies hybridization of Gossypium barbadense L. are an urgent genetical task, whose applications involve plant breeding and seed industry. The purpose …
Symbiotic nitrogen fixation in legumes as a genetic and selection trait. K. K. Sidorova, M. N. Glyanenko, T. M. Mishchenko, E. Yu. Vlasova, V. K. Shumny
Abstract: The results of long-term studies on legume symbiogenetics and breeding are summarized by the example of pea Pisum sativum L. A collection of symbiotic mutants was developed by chemical and radiational mutagenesis of pea varieties and genetically characterized. Various sym …
The history of Drosophila studies: steps in the development of genetics. N. N. Yurchenko, A. V. Ivannikov, I. K. Zakharov
Abstract: Experimental genetic studies of Drosophila were initiated by T.H. Morgan in 1910, when he discovered the sex-linked white-eyed mutation, white. This discovery commenced the transformation of Mendel’s “hereditary factors” to more specific but no less enigmatic W.L. Johanssen’s “genes”. Owing …
Mendel: corroboration of the idea of binary trait coding by methods of statistical physics. О. V. Trapezov
Abstract: The paper by the Augustinian friar Gregor Johann Mendel “Experiments on Plant Hybridization” laid the foundation of the new field of knowledge, genetics, 150 years ago. It claimed that any character was determined by two factors. On the one …
Pea (Pisum sativum L.): the uneasy fate of the first genetical object. O. E. Kosterin
Abstract: Pea (Pisum sativum L.) is an important vegetable and forage crop capable of improving soils via symbiotic nitrogen fixation. It is of special importance in Russia as a crop adapted to high latitudes and an inexpensive source of plant …
Gregor Mendel: my time will come. Yu. M. Novikov
Abstract: Gregor Mendel and his work have traditionally attracted well-deserved attention of scientific society. The purpose of this article is to study the background and prerequisites of Mendel’s formation as a personality and scientist, the motivation of his scientific interests …
