234 REPORTS ON THE STATE OF SCIENCE. — 1915. 



Experiments by H. B. Killby. 

 The experiments on Beans (Phaseolus) and Marrows, begun three 

 years ago, have been carried further. Interesting points have arisen in 

 both cases, but further work is necessary for their elucidation. 



Experiments hy A. E. Gaibdnee. 

 Work on Wallflowers and on Tropseolum has been continued; the 

 work on the Wallflower is approaching completion. 



Experiments by E. E. Saunders. 



Further work has been carried out during the year on Foxgloves 

 and Stocks. In the case of Foxgloves progress is necessarily slow, as 

 two years are required for each generation. The further work has 

 given indication that in respect of one of the characters investigated 

 the species is eversporting, but a fuller analysis of the behaviour of 

 individuals is necessary before a full statement can be made. Inci- 

 dentally it has been found in the course of cross-fertilisation of heptan- 

 drons with peloric plants that these two abnormal conditions are 

 inherited independently. 



From the results obtained with Stocks it is hoped that it may be 

 possible to show how an eversporting type may be synthesised from a 

 true-breeding individual. Further pi'ogress has been made in the study 

 of the inheritance of the half -hoary character, and in the identification 

 of types required by theory but not met with in commercial material. 

 With regard to the occurrence of doubles, the results obtained show 

 that the excessive percentage of doubles sometimes obtained by growers 

 and quoted in their catalogues is probably due to unconscious selection, 

 and that the actual output of doubles is not in excess of the theoretical 

 estimate.
