To obtain a high-quality source material for breeding new varieties of garden pea studied biochemical and technological properties of 450 sample grades collection. As a result, selected varieties, sources that had green peas in a high content of individual chemicals and combine incorporates several of these substances. These varieties have different duration of the growing season. Among them, identified those with green peas excessive ripeness not for a long time. Such quality varieties are especially important because provides over a longer period of receipt of a high quality green peas in a cannery. In addition, the collection highlighted garden pea varieties of high quality seed in biological maturity. The selected varieties were included in the selection process and, based on a number of new varieties garden pea, providing conveyor receipt green peas for processing plants.

The article features the results of variability study for one of the productivity characteristics in green pea, namely «number of seeds in the seedpod» for hybrid  populations and for the selections made thereof. Statistical methods of analysis have established the levels of variability for the characteristics in F2 original population , the impact of the selection completed within F2 onto the variability of F3 hybrid population. This shows the efficiency of repeated selection from F3 population and its impact onto the level of expersiioon of the characteristic being studied in the resulting F6 population. As a conclusion, a good time is set for practical breeding with the characteristic of «number of seeds in a seedpod» for  the selection, as well as for the methods for achieving its stable expression, that is to facilitate the decrease of durations and means for the tests conduct.
