Abstract

BACKGROUND: Russia is one of the largest peanut-buying countries. At the same time, in the south of the country, a number of zones meet the requirements for the cultivation of peanuts. AIM: Identification of a new source material for peanut breeding by the method of ecological and geographical testing of collection samples. MATERIALS AND METHODS: The work used 30 of peanuts accessions from the VIR collection of various origins. To assess the stability of productivity, standard deviation (s), coefficient of variation (Cv) and regression (i) for environmental conditions according to Eberhart and Russell were used. RESULTS: As a result of the study, the possibility of growing individual varieties of peanuts in the south of the RF under modern conditions was confirmed. It was determined that some samples are more productive and suitable as starting material for the conditions of the Krasnodar Territory (k-283, k-1157), others for the conditions of the Astrakhan region (k-317, k-868). The accessions of the VIR collection were found to be more productive at 2 points experience, also marked as plasticity k-751, k-283, k-626, k-1533, k-1987. CONCLUSIONS: In contrasting conditions (two geographical points for 3 years of study), peanuts accessions were identified that strongly react to changes in environmental conditions. Stable and plastic in productivity accessions can serve as the initial breeding material. It has been established that peanuts can be cultivated in the south of the Russian Federation, namely in the Astrakhan Region and the Krasnodar Territory.
