The purpose of the current study was to determine the quantitative and qualitative indicators of seeds of pea samples. The study was carried out in the southern part of the Rostov region in the fields of the FSBSI Agricultural Research Center “Donskoy” in 2021–2023. The objects of research were 12 pea samples developed by the ARC “Donskoy”. The zoned variety ‘Aksaisky Usatiy 5’ was used as a standard. Quality characteristics of peas, such as protein percentage in seeds and their ability to boil soft, are highly dependent on environmental conditions and often have a negative correlation with seed productivity. One of the goals in pea breeding is to change this inverse correlation between productivity and seed quality. The mean productivity of the varieties and lines in the Competitive Variety Testing through the years of study was 3.66 t/ha on average. The standard ‘Aksai Usatiy 5’ (3.46 t/ha) was reliably exceeded by such varieties and lines as ‘G-1181’ (4.17 t/ha), ‘Kazak’ (4.02 t/ha), ‘AKM’ (3.99 t/ha), ‘G-1313’ (3.80 t/ha). The samples with the highest protein percentage (second quality class, 22.0–25.0 %) were ‘Aksaysky Usatiy 5’ (23.7 %), ‘Skif’ (24.4 %), ‘Kazak’ (23.1 %), ‘AKM’ (23.6 %), ‘G-1141’ (24.3 %), ‘G-1172’ (25.0 %), ‘G-1181’ (22.3 %). The mean boiling time was 75 minutes. The minimum boiling time was 63 minutes for the varieties ‘Aksaisky Usatiy 5’, ‘Skif’, 65 minutes for the line ‘G-1234’ and 70 minutes for the line ‘G-1288’. The mean coefficient of the ability to boil soft over the years of study was 2.20, varying from 1.92 to 2.61. The mean protein yield over the years of study was 0.85 t/ha. The varieties ‘Kazak’ (0.94 t/ha), ‘AKM’ (0.93 t/ha) and breeding lines ‘G-1181’ (0.93 t/ha), ‘G-1313’ (0.90 t/ha) showed the best indicators. The maximum values of protein yield were identified at maximum productivity of 4.2–4.3 t/ha and 23.5–24.0% of protein in seeds.
