ПРЕБРИДИНГОВЫЕ ИССЛЕДОВАНИЯ БОБОВ ОВОЩНЫХ - VICIA FABA L

Pre-breeding research on 20 accessions from collection of broad bean (Vicia faba L.) of All-Russian Research Institute of Vegetable Breeding and Seed Production has been performed. Four traits such as height of plan, height of stem from soil surface up to lowest bean (most important characteristics for mechanized harvesting), number of seeds in the bean, and the size of seeds were taken to be studied. Four promising accessions N 9, N 27, N 33, N 15d-vf18096 that have a set of three valuable characteristics, namely the high seed yield, large seeds, and great height of the stem from the soil surface up to lowest bean have been selected out at previous stage of breeding program.Пребридинговые исследования 20 образцов из коллекции бобов овощных (Vicia faba L.) ВНИИССОК проведены по четырём параметрам: высоте растения; высоте стебля до прикрепления нижнего боба, характеризующего образец с точки зрения пригодности для механизированной уборки; числу семян в бобе и размеру семени. Отобрано 4 источника с комплексом трёх хозяйственно ценных признаков: высокой семенной продуктивностью, крупными семенами и высоте прикрепления нижнего боба - №№ 9, 27, 33 и детерминант №15д-вф18096

Palaeoecological and palaeoclimatic conditions on the Karelian Isthmus (northwestern Russia) during the Holocene

© 2020 University of Washington. Published by Cambridge University Press. The Holocene evolution of climate in easternmost Fennoscandia and adjoining regions is poorly known, compared with regions to the west. To address this, a 224-cm-long sediment core from Lake Medvedevskoe, situated on the Central Upland of the Karelian Isthmus, northwestern Russia, was examined to investigate variations in the Holocene climate. Analyses indicate that the dry and cold late Pleistocene climate was replaced by the warmer and more humid early Holocene climate after ca. 10.5 cal ka BP. During the early Holocene, the lake transitioned from an oligotrophic to a mesotrophic state, characterized by a Corynocera ambigua/Microtendipes pedellus-type phase, which has been found in other lakes across Fennoscandia. Taxonomic shifts in the chironomid and cladoceran communities associated with climatic amelioration were identified at ca. 10.6 and 9.17 cal ka BP using breakpoint analysis. Reconstructed July temperatures indicate climatic patterns comparable to those seen in eastern Fennoscandia. The warm period between ca. 9.5 and 5.5 cal ka BP (T July 14.5-15°C) was interrupted by a slight cooling between ca. 8.5 and 8.1 cal ka BP, possibly relating to the 8.2 event, with peak temperature reached at ca. 7.8 cal ka BP. Neoglacial cooling started after ca. 5.5 cal ka BP, the median reconstructed July temperature dropped to 2-3°C cooler than present (mean T July 13.5°C) before recovering in recent time
