MUTATION IN MATTHIOLA

TABLE 5 



Cultures of 1908. Time from sowing to emergence of corolla of earliest flower 

 of primary cluster. Frequency distributions. 11 



Daggers (t) indicate the position and number of apparent mutants. Double 

 daggers (t) indicate inheritance of parental type (here, early); all single progeny 

 of WG9-C10 here reported have been tested for inheritance of this type. The 

 conventional statistical constants corresponding to the house totals of tables 5 

 and 6 have been published (Frost, 1911); the means for flowering given there 

 are too high by one half-day. 



b To time of observation (upper limit of one-day class).
