June, '14] MENDELISM IN MELONS. 57 



Season 1912. Seeds of hybrid melons, No. 27 and No. 34, 

 were selected for the purpose of ascertaining whether a pure 

 hybrid type had been fixed in these hybrids, Melon No. 27 

 having a green skin and Melon No. 34 a yellow skin; both these 

 hybrid melons were close pollinated. 



Season 1913. Seeds of Melons No. 27 and No. 34, which 

 were close poUinated season 1912, were tested out to confirm 

 work in fixation of type, and resulted in a duplication of F4 

 generation, thereby proving fixation of type in these hybrids. 



The work indicates that, when such pairs of characters as are 

 here considered have been crossed, they show a blend in the 

 Fi generation rather than dominance of either character. In 

 the F2 generation the segregation of dominant and recessive 

 characters occurs. 



Six pairs of characters have been studied in the melon, and 

 show dominance and recessiveness as follows: 



Dominant. Recessive. 



Yellow color of skin. Green color of skin. 



Round form of fruit. Obtuse-elhptical form of fruit. 



Large size of seeds. Small size of seeds. 



Ribbing. Non ribbing. 



Netting. Smoothness. 



Large size of fruits. Small size of fruits.
