Combining abilities of inheriting first pod height of some French bean lines -Phaseolus vulgaris L.-

First pod height is an important trait, especially for snap bean since it enables the mechanical harvesting. Cultivars with low first pod height may be cut, damaged or not harvested by mechanical harvesting. In our investigation six different snap bean genotypes were used for examination of the first pod height and diallel analysis. The result was obtained by using method 2 model 1 GRIFFING (1956) for analysis of combining abilities. The mode of inheritance was different, as the results showed - from intermediate to super dominance, for both generations (F1 and F2). Analysis of combining abilities showed both influence of additive and dominant gene effects. Combination Sumadinka x Zora is suitable for further breeding for first pod height.
