TABLE 13 

 Analysis of the FI generation of the cross f. typica M (homozygous) X mul.formosa (a'QFF X a'pjf). 



The pistillate parent belonged to the Fa generation of the cross mut. formosa X mut. lati- 

 folia C. Each of the cultures consists of only flat-leaved plants. Of the 210 plants grown to 

 maturity, taken in part from each of the nine cultures, 204 proved to be f. typica, and the 

 remaining 6 were of other flat-leaved types, 3 were mut. dimorpha, 1 was mut. fallax, 1 was 

 mut. sub-latifolia (?), 14 and 1 was undetermined. 



TABLE 14 



Analysis of the F 2 generation resulting from self-pollination of f. typica plants chosen at random 

 from the FI generation (see table 13) of the cross f. typica M (homozygous) X mut. formosa 

 X a'Qff). 



Each of the cultures contains both flat-leaved and revolute-leaved plants, in approximately 

 a 3 : 1 ratio. Of the 74 plants from three of these cultures, grown to maturity, 58 proved to be 

 f . typica and 16 proved to be mut. formosa. 



14 An undescribed mutation.
