AGRO-ECOLOGICAL EVALUATION OF SAMPLES PEAS IN TAIGA ZONE
The study area is different extreme conditions, which allows for assessment of selection of samples for adaptability. Creating adaptive varieties remains the most accessible means of intensification of grain production. The study area is characterized by extreme climatic and edaphic conditions. The object of research is the pea (Pisum sativum L.). The results of the study accessions three maturity groups: early-maturing, medium and medium-late. The standard grade used Narymsky 11. To assess the adaptive capacity of the samples used the technique to identify potential productivity and adaptability of the varieties and forms of selection in terms of «productivity.» Feature adaptation of plants to environmental conditions expressed adaptive capacity. To estimate the sample for this indicator shows the data for three years with contrasting conditions. In the group of early varieties adaptability factor was 0.95.1.20, the group of mid - 0.80.1.40, the group of medium - 0.89.1.02. Thus, in each maturity group number is highlighted with high adaptive capacity. All the studied samples tendril-type at the taiga has a low coefficient of adaptation (0.8.1.0). This indicates a more narrow range of conditions conducive to their high yield.
