Abstract

The analysis of meteorological data obtained daily for 67 years was made to select the criteria for evaluation of hardiness and wintering of winter crops. The highest repetition frequency of disadvantageous winters was observed in 1960-s. The increase of temperature and precipitation during the winter in the past thirty years has created advantageous conditions for cultivation of winter crops in Saratov Region. 

Key words:
