Results of perennial study of 31 varieties of honeysuckle, 19 varieties of seabuckthorn, 13 elite plantlets of filbert, and 6 forms of quinceon productivity and stability of fructification under conditions of Kirov region are presented in the article. The researches were shown sharp variations of productivity levels of non-traditional crops in dependence of weather conditions of year. Moreover, fructification of sea buckthorn suffered significant influence of damages with seabuckthorn fruit fly. As a result of investigation high-productive (1.43-2.82 kg/bush) honeysuckle varieties were selected: Slavyanka, Bogdana, Amphora, Viola, Nizhegorodskaya rannyaya, Morena, and Suvenir. Three varieties had high and stable productivity level: Suvenir, Viola, and Nizhegorodskaya rannyaya. Form 988-11 had good level of stable productivity. Study of productivity in 19 samples of sea buckthorn had shown its significant variability by years of researches from 0.39 (2007) up to 7.0 (2008) kg/plant. Grouping of investigated varieties on level of fructification allowed to select high productive (17/91, Kudrina, Dyujmovochka, Nizhegorodskij souvenir, 7-70-13-91) and productive (Zarevo, 24/91) samples. Four buckthorn varieties had stable fructification – Kudrina, Zarevo, 17/91, and 24/91. Perennial study of elite forms of filbert selected on earliness had shown possibility of obtaining of every-year yield of this crop under condition of northern border of its natural area. Forms 1-3-27, 3-12-27 were selected having high and stable productivity level as well as sample 1-2-21 with stable good level of fructification. Study of influence of level of quince plants' subfreezing on its productivity had shown an existence of middle negative relation between these two parameters (r = -0.66). Form 3-99 was selected on productivity. Sample 6-99 had middle stable productivity level.
