Essay. In 2010−2012 y.y. 10 natural M. baccata coenopopulations were studied in the Republic of Buryatia and the Trans-Baikal Territory. It was studied economic-biological signs: the total degree of freezing of the tree, the general condition of the tree, the degree of damage caused by pests, the degree of fruiting, fruit quality. The minimum average degree of freezing of trees was found in Nyuko and Romanovo coenopopulations of Kabansk area. In the summer of 2010 more than 50% of leaves, shoots and fruits of four individuals of east-transbaikalian coenopopulation (Nizhnetsasuchey) were hit by pome cultivated plants’ pests: the codling moth and green aphids. The reason is dryness of the climate: the maximum average temperature and average minimum relative humidity in September 2010 in comparison with other areas of research have contributed to an increase the number of insect pests. The highest average harvest was given an individual of apple-berry of Kurdyum and Romanovo coenopopulations (1399.0 g and 1708.1 g, respectively). There were only 180 to
274 fruits on Gusinoozersk coenopopulation’ M. baccata trees. The visual harvest ranged here from 31 to 143 grams from the tree. It was revealed a forms with good taste (Burlakovo, Nyuki and Sotnikovo coenopopulations). These fruits have a good table taste. It was found trees with high levels of economic- biological signs (Burlakovo coenopopulation). Fruits were divided into two groups: 1) fruits of poor quality; 2) fruits of very poor quality.
