TI  - Exploring Heterosis in Melon (Cucumis melo L.).

AB  - Heterosis is the superiority of an F(1) hybrid over its parents. Since this 
      phenomenon is still unclear in melon, a half diallel experiment based on eight 
      genetically distant breeding lines was conducted in six environments of Central 
      Italy, assessing commercially important traits: yield, total soluble solids 
      (TSS), and days to ripening (DTR). To estimate the additive (general combining 
      ability; GCA) and the non-additive gene effects (specific combining ability; 
      SCA), yield was analyzed by Griffing's methods two and four, and the results were 
      compared to the GGE (Genotype plus Genotype by Environment interaction) biplot 
      methodology; TSS and earliness were evaluated only by Griffing's method four. 
      Overall, GCAs were significantly more relevant than SCAs for all examined traits. 
      Least square means (LsM), mid-parent heterosis (MPH), best-parent heterosis 
      (BPH), as well as Euclidean and Mahalanobis' distances were calculated and 
      compared with the genetic distance (GD). As a few correlations were found 
      statistically significant (only for TSS), it was difficult to predict the value 
      of a hybrid combination only by knowing the genetic distance of its parents. 
      Despite this, heterosis was observed, indicating either the presence of epistatic 
      effects (additive x additive interactions) and/or an underestimate of SCAs 
      embedded within Griffing's method. The significant Env x Entries source of 
      variation suggests development of hybrids in specific environments. The results 
      are discussed with a breeding perspective.
