本试验以14个西瓜品种(系)间杂种及13个亲本为试材,分析不同杂交组合单株产量,单果重,单株结果数,果肉可溶性固形物含量,田间抗性等性状的杂种优势及不同性状的优势强度。试验结果表明64.3%的组合单株产量表现超中优势,优势百分率在3.77-63.52%之间,50%的组合表现单株产量超优亲优势。71.4%的组合单瓜重表现超中优势,优势百分率在4.62—33.64%之间。单株的结果数50%的组合表现超中优势。没有表现超亲优势的组合。中心可溶性固形物含量有78.6%的组合表现超中优势,边糖含量有71.4%的组合表现超中优势,其中超中优势率分别为2.44—12.18%和1.56—41.18%。中心可溶性固形物含量有21.4%的组合表现超亲优势。边糖含量有28.6%的组合表现超亲优势。抗性优势中有78.6%的组合表现超中优势,其中35.7%的组合表现出超亲优势。在所调查的性状中单株产量和抗性的优势最高,其次为单瓜重、中心可溶性固形物含量、边糖,单株结果数的优势最低。
In this experiment, the hybrids of 14 watermelon cultivars (lines) and 13 parents were used as materials to analyze the heterosis of yield per plant, fruit weight per plant, fruit number per plant, soluble solids content of flesh, field resistance and other traits And the strength of different traits. The results showed that the yield of 64.3% of the combined plants showed an over-mid-superiority, with the dominant percentage ranging from 3.77 to 63.52%. The combination of 50% showed superior yield superiority progeny. 71.4% of the combined single melon weight performance super-medium advantage, the dominant percentage between 4.62-33.64%. A combination of 50% of the number of fruits per plant showed an over-mid-advantage. No combination of super-pro superiority. The middle soluble solids content of 78.6% showed a super mid-superiority, while the sugar content of 71.4% showed super-mid-superiority. The super mid-superiority rates were 2.44-12.18% and 1.56-41.18%, respectively. A combination of 21.4% soluble solids content in the center showed super-pro-dominant. 28.6% of the sugar content of the combination of super-pro-edge advantage. Among the resistance advantages, 78.6% of the combinations showed an over-mid-advantage and 35.7% of the combinations showed the superiority of the super-parents. Among the investigated traits, the yield per plant and the resistance had the highest advantage, followed by the single melon weight, the center soluble solid content, the edge sugar and the number of fruit per plant.
