Abstract:

Investigation and statistical analysis were carried out on berry color , shape , mass and size of 94 varieties of seedless grape and 40 varieties of Kyoho type grape collected in National Grape Germplasm Repository Zhengzhou for three years. The results showed that there were profile genetic diversity in seedless grape. Variation coefficient both berry mass and berry size were much greater than that of Kyoho type grape. The average mass of
seedless grape was in range from 1.0 to 5.0 g . Almost half of tested varieties had medium mass in 1.5 - 2.5 g ,The available description standards both domestic and international was considered to be not suitable for evaluating berry size and berry mass of seedless grape. Based on the result of the study , the new additional method for this purpose are suggested.
