The Russian-Belarusian cooperation in breeding of legumes and onion crops has resulted in development of new cultivars of pea (Samorodok), bean (Phaeton and Mignon), onion (Palesskaya znahodka, Patrida and Vermeles), winter garlic (Dubkovsky Asilak), which were included in 2014 in the State Register of the Republic of Belarus.

In the laboratory of leguminous crops of the “All-Russian Scientific Research Institute of vegetable breeding and seed production”, more than 100 samples of pea are studied annually. As a result, pre-breeding collection of the sources of agronomical valuable traits was developed. It is utilized for development of new pea varieties resistant to lodging. In 2012- 2014, the crossing were conducted. As a result of selection in F2-F6, the lines of different groups of maturity with lodging resistance were selected. These transgressing forms are suitable for canning, deep freezing, and drying. The following samples are recommended for development of high yielded varieties: «102- 82А5Б4» is the middle-early variety, the progenitor of early ripening cv. «Korsar» applied for the state variety trial in 2015 and two promising samples «15 КСИ 15» and «9 КСИ». The «16-05» is the middle-early variety, the transgressive form for the trait «seed amount per nod» with high attachment of lower bean. The sample «K-8915» is the middle-early genotype, high productive, with high attachment of lower bean. The sample «Troyika» is recommended for development of high productive, late ripening initial breeding material. As a result of step crossing this sample is characterized by late maturity, by three bean per nod, and by high attaching of lower bean. The sample «CM-10 m» is distinct in the aphyllous type of leaf, resistance to powdery mildew, paired bean, suitable for canning and drying. This sample was selected as a transgressive form for stem anatomy structure (spongy cell tissue) from sample developed by complex step hybridization. Owing the distinctive feature in the stem anatomy structure, this sample can be recommended as a main parental form for development of varieties resistant to lodging.

The promising pea varieties for canning with an optimum combination of elements of yield production have been selected based on utilization of geographically dispersed and morphologically different forms in progeny of diallel crossing. A comparative evaluation of the severity selection in different hybrid generations is shown, from which conclusions are drawn about the breeding value of parental forms.

The article presents the methods and results of the competitive breeding of promising high-quality varieties of vegetable green pea for canning, as well as the main achievements of FGBNU VNIISSOK.
