摘要: 在普通大棚和露地两种栽培条件下鉴定西瓜裂果性,制定西瓜的裂果性状分级标准和抗性评价标准;田间鉴定发现,14个稳定自交系中有13个发生不同程度的裂果,占92.86%;两种栽培环境对裂果的影响效应有差异(F=27.048**,F0.01=3.91),但抗裂程度显著相关(r=0.937**,r0.01=0.6614,df=13)。不同基因型西瓜裂果性差异显著(F保护地=10.7218**,F露地=5.783**,F0.01=1.90,df=13),其中,材料‘x-101’在两种不同的栽培条件下均不裂果,性状稳定,且其综合品质表现优良,可作为抗裂育种的材料。

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.
