Abstract: In order to compare the growth of different blueberry varieties cultivated in solar greenhouse,the study used six blueberry varieties（O′Neal,Misty,Bluecrop,Coville,Blomidon and Brunswick）as the research object,which cultivated in solar greenhouse,investigated and measured mature period,botanical characteristics,fruit quality.The results showed that the order from higher to lower of the mature period of six blueberry varieties was O′Neal＞Blomidon＞Bluecrop＞Brunswick＞Misty＞Coville;the order from higher to lower of the plant heigh of bush of six blueberry varieties was Coville＞Bluecrop＞O′Neal＞Misty＞Brunswick＞Blomidon;and the order from higher to lower of the leaf longitudinal diameter of six blueberry varieties was O′Neal＞Coville＞Bluecrop＞Brunswick＞Misty＞Blomidon;the order from higher to lower of the leaf transverse diameter of six blueberry varieties was Coville＞O′Neal＞Bluecrop＞ Misty＞Brunswick＞Blomidon;the order from higher to lower of the average fruit weight of six blueberry varieties was O′Neal＞Coville＞Misty＞Bluecrop＞Brunswick＞Blomidon;and the order from higher to lower of the soluble solid content of six blueberry varieties was Brunswick＞Blomidon＞O′Neal＞Coville＞Bluecrop＞Misty.Comprehensive evaluation according to the result of the observation indexes of six blueberry varieties,O′Neal,Misty and Brunswick are suitable for use as picking or fresh food and so on.The two varieties of Bluecrop and Coville are good materials for production and processing,with good ecological adaptability and strong stress resistance.The variety of Blomidon can be widely planted in areas with poor climatic and soil conditions.
