                  The purpose of this work was an analysis of the productivity, environmental plasticity
            and resistance to diseases of  different cultivars of beans (Phaseolus  vulgaris L.) in a wide
            range of climatic conditions and their response to inoculation by endophytic bacteria. The
            objects were the local cultivars Ufimskaya and Zolotistaya and a new cultivar Elsa of French
            selection (sample No. 14693 from the VIR collection). Endophytic bacteria strains are stored
            in the collection of Bashkir Research  Institute  of Agriculture. Field  small-scale  experiments
            were carried in the period of 2003-2018 years at the hydrothermal coefficients 0.2–1.6.
                  The seed productivity and yield of all bean varieties were close: 7.3–9.3 g/plant and
            19.7–22.0 g/m . But the coefficients of variation of yield for the Ufimskaya and the Zolotistaya
                           2
            cultivars were 24 and 29 %, for the Elsa cultivar – 57 %. In favorable climatic conditions, the
            Elza cultivar gave the high seed productivity 26.7 g/plant, but under severe drought it was 0.6
            g/plant, which is 3 times lower than that of local cultivars. Correlation was low between the
            seed productivity of the Zolotistaya and the Ufimskaya cultivars plants and the sum of active
            temperatures (r = 0.46, r = 0.59). The Elsa  cultivar was more dependent from favourable
            conditions: the correlation coefficient between these indicators was high (0.84). Between the
            duration of the period above 15 °C and seed productivity, the correlation coefficients for the
            Ufimskaya and the Zolotoistaya cultivars were low (0.20 and 0.40), and for the Elsa cultivar
            0.69. Attitudes toward biotic stress were found in the studied cultivars in the 2015 season,
            when an increased level of leaf lesions was observed. The Elsa cultivar was resistant to them.
            The Zolotoistaya and Ufimskaya cultivars were moderately susceptible to leaf diseases at the
            beginning of the growing season. But at the end of the growing season, healthy leaves grew on
            plants of the Ufimskaya cultivar, and the Zolotoistaya cultivar plants had 90 % damaged
            leaves. In relation to root rot, the Ufimskaya cultivar was more resistant than the Zolotoistaya
            and Elsa cultivars.
                  The lack of adaptive traits of plants  can be complimented by inoculation with
            endophytic bacteria. On a high infectious background in 2015, inoculation of the Ufimskaya
            and the Zolotistaya cultivars by the composition of endophytic  Bacillus  subtilis SG12 and
            Rhizobium leguminosarum SG13 promoted the seed productivity in 1.5–2.0 times compared
            with control, decreasing diseases. In 2018, without biotic stress, but in conditions of abiotic
            stress, the inoculation of Zolotistaya cultivar with endophytic B. subtilis 26D contributed to an
            increase of seeds yield on 39 % compared with control, and inoculation of Ufimskaya cultivar
            with endophytic  B.  subtilis 10-4 promoted seed weight by 31 % than control. Seed
            productivity of the resistant to diseases Elsa cultivar, in favourable abiotic conditions of 2015,
            was raised on 17 % compared with control under inoculation by suitable R. leguminosarum
            2630 strain.

            endophytic bacteria.
