Genetic Analysis of Hybrid Watermelon and its Parents

Zhang Yabing(Seed Company ,Anhui Province.Hefei,230001)  
The esterases and peroxidases in the six hybrid watermelons (Xingchen,Xinghongbao,Zhenza-5,Jinzhongguanlong,Wanza-1 and Jubao-1)and their parents were analysed in order to master their organization and isozymic hereditary.The results showed :(1)the esrerases among paternals or maternals appeared similar except Jinzhongguanlong's parent, but between paternal and maternal of each hybrid combination different;(2)the esterase appeared that maternal was incomplete dominance in the six F 1 materials and;(3)the peroxidase of the six F 1 and its parents appeared similar except Zhenza-5.Besides,the feasibility of screening parents,combining hybrid and forcasting heterosis was discussed by means of esterase analysis.
