The aim of the research is to breed short climbing, early maturing, high-yielding varieties of squash in the natural and climatic zone of Uzbekistan.Methods. The samples of squash 0044SQ (Holland) and BT+KB-001 (Turkey) were taken from the gene pool of the Research Institute of Plant Industry (Uzbekistan) in 2012 for breeding work. In 2013, squash samples were studied in the nursery of the source material, where they were evaluated for biological and economically valuable traits. Individual selection of plants was carried out. In further breeding work (2014-2016 and 2018), the lines LZ-2513 and LH-1916 were distinguished.Results. The method of analytical breeding created short-climbing, early maturing, high-yielding of squash lines LZ-2513 and LH-1916. Line LZ-2513 has rounded fruits of light green color. The LH-1916 variety has elongated, dark green fruits. Competitive variety trials of new lines were conducted in 2019-2020. Unumdor variety zoned in the republic served as a standard. It was found that from sprouting to maturity of the fruit in the line LZ-2513 is 44 days, in the line LH-1916 – 45 days. High marketable yield was recorded for squash line LZ-2513 – 18.3 tons/ha (122% of the standard); in line LH-1916 marketable yield was 16.4 tons/ha (112.4% of the standard). This year we organized the primary seed production of squash lines LZ-2513 and LH-1916 for multiplication.Conclusion. Promising for cultivation in conditions of Uzbekistan squash line LZ-2513 Orbita (NAP 20200087) and line LH-1916 Viridi (NAP 20200088) were submitted to the Intellectual Property Agency under the Ministry of Justice of the Republic of Uzbekistan to be patented.

Pea (Pisum sativum L.) is a widespread leguminous crop. It is used for food purposes, as well as concentrated high-protein feed  for  farm animals.  In addition  to a great nutrition value, a balanced amino acid composition and an excellent  taste,  it  is peas that is capable to produce large grain yields even in the risky arable zone, which most of the territory of our country belongs to. The development of the new high-protein, productive pea varieties that most fully realize the soil-climatic potential and meet the requirements of agricultural production is an urgent concern of breeders. The purpose of the current study was to develop a new pea variety, adapted for cultivation in the Republic of Bashkortostan. There has been estimated the collection peas material on morphobiological and economically valuable traits. The best varieties have been used for hybridization. Among the hybridized breeding forms there has been identifed the line “L-31315/14” which possesses economically valuable traits. In 2019, this line was sent to the State Variety Testing as the variety “Pamyati Popova”. The new variety was bred by multiple individual selection from a hybrid population “K-7992” (Korea) × “Barbel”. The variety “Pamyati Popova” is a middle ripening variety with 64–78 days of vegetation period. The kernels contain 20.7–22.4% of protein. The variety is of good taste and cooking properties. Its disease and pests’ resistance is similar to that of the standard variety. According to the Competitive Variety Testing, the average yield increase of the variety “Pamyati Popova” was on 3.9 hwt/ha in 2016–2019. The largest kernel yield of the variety was 26.9 hwt/ha in 2017.

Селекцией моркови столовой в России занимаются ФГБНУ ФНЦО, Агрохолдинг «Поиск», ООО «Селекционная станция имени Н.Н. Тимофеева» и другие. Цель работы – подбор исходного материала и создание новых линий-опылителей моркови столовой с одновременной доработкой имеющихся в генетической коллекции ВНИИО-филиала ФГБНУ ФНЦО. Исследования проводили в 2011-2019 годах в условиях Московской области на экспериментальной базе и в селекционном центре ВНИИО-филиала ФГБНУ ФНЦО. Материалом для работы служили сорта и гибриды отечественной и иностранной селекции, селекционный материал, полученный от межлинейных и межсортовых скрещиваний. Селекционную работу проводили методом многократного инбридинга (до I3-4). По мере отработанности селекционного материала на устойчивость к альтернариозу и фузариозу, морфологическую выровненность, переходили на сибсовые скрещивания. Селекционный процесс по созданию новых линий-опылителей осуществлялся в питомнике исходного материала и селекционном питомнике. В результате селекционной работы было получено 14 новых линий-опылителей моркови столовой и доработаны 4 линии, имеющиеся в генетической коллекции ВНИИО-филиала ФГБНУ ФНЦО. Большая часть линий-опылителей (5 шт.) принадлежит сортотипу Курода, четыре - Берликум/Нантская, по три – Берликум, Флакке, две – Шантенэ, одна – Нантская. Общая урожайность линий варьирует от 70,9 до 110,0 т/га. Наибольшую урожайность формировали линии 93-2, 98, 56-2. Значительные пределы содержания β-каротина (11,1 – 16,8 мг%) связаны с происхождением линий. Отмечено, что инбредные линии, полученные из исходного материала иностранной селекции содержат меньше β-каротина. Шесть линий относятся к позднеспелым, десять – к среднеспелым, две – к раннеспелым. В результате оценки инбредных линий по устойчивости к грибным болезням установлено, что 16 линий принадлежат к слабовосприимчивым на инфекционных и естественном фонах, две линии – средневосприимчивые: 805 – на инфекционном фоне Alternaria, REW – по двум инфекционным фонам. На естественном фоне все линии относятся к слабовосприимчивым. The selection of carrots in Russia is carried out by FSBSI FSVC, Agroholding «Poisk», LLC «Breeding station named after N.N. Timofeeva» and others. The purpose of the work is to select the initial material and create new pollinating lines for carrots with the simultaneous refinement of those in the genetic collection of the ARRIVG- a branch of the FSBSI FSVC. The studies were carried out in 2011-2019 in the conditions of the Moscow region on the experimental base and in the selection center of the ARRIVG - a branch of the FSBSI FSVC. The material for the work was varieties and hybrids of domestic and foreign selection, breeding material obtained from interline and intervarietal crosses. The breeding work was carried out by the method of multiple inbreeding (up to I3-4). As the breeding material worked out for resistance to Alternariaand Fusarium, morphological uniformity, they switched to sib crosses. The breeding process for the creation of new pollinator lines was carried out in the nursery of the source material and the breeding nursery. As a result of breeding work, 14 new lines-pollinators of carrots were obtained and 4 lines, which are available in the genetic collection of the ARRIVG- a branch of the FSBSI FSVC, were modified. Most of the pollinator lines (5 pcs.) belong to the Kuroda variety type, four - Berlikum/Nantes, three each - Berlikum, Flakke, two - Chantenay, one - Nantes. The total yield of the lines varies from 70.9 to 110.0 t/ha. The highest yield was formed by lines 93-2, 98, 56-2. Significant limits of β-carotene content (11.1 - 16.8 mg%) are associated with the origin of the lines. It was noted that inbred lines obtained from the source material of foreign selection contain less β-carotene. Six lines are late maturing, ten are mid-maturing, two are early maturing. As a result of the assessment of inbred lines for resistance to fungal diseases, it was found that 16 lines belong to weakly susceptible on infectious and natural backgrounds, two lines are moderately susceptible: 805 - according to the infectious background Alternaria, REW - according to two infectious backgrounds. On a natural background, all lines are weakly receptive.
