MAINTENANCE AND STUDY OF THE GENETIC CARROT COLLECTION (DAUCUS CAROTA L.) IN FSBSO ARHCBAN

Abstract

The aim of work is to support and study the genetic collection of carrots (Daucus carota L.) of Federal Horticultural Center for Breeding, Agrotechnology and Nursery (ARHCBAN) in the Moscow Region. The studies were carried out in accordance with the generally accepted method. The area of accounting plots in experiments is 2–10 square meters. m., the repetition is fourfold. The standart variety is carrot variety dining Nantskaya-4. In the laboratory of vegetable crops and potatoes of the Center for the Gene Pool and Bioresources of Plants of the ARHCBAN 120 collection samples of carrots are maintained and stored annually. In 2018, the genetic collection of the dining carrot was replenished with 17 sources with a complex of economically valuable traits. Early maturing varieties of carrots with a growing period of up to 70 days were identified: the Parizhskiy Rynok, Kamila. The combination of parameters of root mass and high  marketability of root vegetables was observed in the varieties Vita Long, Dolyanka, Zholtaya, Dar Podmoskovya, Minchanka, Litvinka. In terms of marketable yields, the following varieties stood out: Alyonka, Litvinka, Vita Long, Dolyanka, Dar Podmoskovya, Leander, Flaker, Minchanka, Samson. When assessing carrot varieties for resistance to brown leaf spot, 5 highly resistant sources were identified: Vita Long, Alyonka, Dolyanka, Flaker, Zheltaya, Dar Podmoskovya, Litvinka. The best collection varieties according to the results of the tasting evaluation were Nanika, Gollandka, Samson, Natofi, Coral, Minsk, Litvinka, Dar Podmoskovya. As a result of studying the collection varieties of table carrots in the conditions of the Moscow region, varieties with valuable economic characteristics were identified. The genetic carrot collection of the dining room of the ARHCBAN has been replenished with new sources of economically valuable traits that can be used in the breeding of highly productive varieties and hybrids.
