Abstract：A novel short-lateral-branching mutant was selected from the west Asian melon P1169329 and used for genetic analysis and correlation analysis of the mutant trait,short lateral branching.The result showed that the total length (TLL) and mean length (MLL) of lateral branches of ‘D581-1 ’ were about 13.40％ and 17.10％ of the common melon germplasm,respectively,and had a stable phenotype during the consecutive seasons.Genetic analysis of F1 and F2generations of ‘D581-1’ (female) crossed with the long-lateral-branching germplasm ‘ H465’ (male) showed that all the F1 individuals revealed a tendency to ‘H465’,and TLL and MLL exhibited a skewed normal distribution with double peaks.These findings inferred that the short-lateral-branching trait was controlled by a major gene and tended to inherit as a single nuclear gene.Correlation analysis of the mutant trait in F2 population demonstrated a moderate correlation with the plant height and a high correlation with fruit fresh weight.
