Abstract: Resistance to fruit cracking in the 14 gene -types watermelon was evaluated under opening and protected conditions.Grades, symptoms characters and rating of fruit -cracking in watermelon are drawn up.13 (92.86 %)of them crack under two conditions.According to the comprehensive evaluation,the variance of the susceptibility indices were significant in opening field (F =5.783**,F0.01 =1.90,df =13)and protected field (F =10.721 8**,F0.01 = 1.90,df =13).The correlation coefficients of susceptibility indices in both conditions were significant (r =0.937**,r0.01 =0.661 4,df =13).x -101 has the immunity to fruit -cracking with good quality,and can be potentially used in the breeding program as the resistant parents to the f ruit -cracking.
