34 "Rogues" in Culinari/ Peas 



Historical Evidence. 



Messrs Sutton have most kindly made a search of their trial-records 

 back to 1886 in the hope of discovering something as to the frequency 

 of rogues in the history of well-known varieties. There are continuous 

 records of the following : 



American Wonder, Blue Peter, British Queen, Champion of England, 

 Daniel O'Rourke, Dr McLean, Duke of Albany, Earliest Blue, Eclipse, 

 Fillbasket, McLean's Little Gem, Ne Plus Ultra, Pride of the Market, 

 Prince of Wales, Sangster's, Telegraph, Telephone, Triumph, Veitch's 

 Perfection, Walker's Perpetual, Yorkshire Gem, Yorkshire Hero. The 

 trial sample in each case consists of 200 — 300 seeds. Of the varieties 

 named, the following six have produced rogues with especial frequency : 

 Dr McLean, Duke of Albany, Ne Plus Ultra, Pride of the Market, 

 Telegraph, Telephone. Plants not true to type of course may come 

 occasionally in any variety, but the " wild " rogues with which we are 

 concerned are only rarely recorded as appearing in the other 16 varieties. 

 It is perhaps worth noting that all the six are varieties characterized 

 by the great width of the leaves and stipules. On the other hand Fill- 

 basket, of which Denaiti'e remarks " feuillage...particulierement leger 

 pour une race demi naine," is not once recorded to have thrown one of 

 these rogues. 



Certain varieties have pods curved as a normal feature, and, since 

 they have already one of the definite rogue features, it might be 

 expected that they would commonly throw rogues. It is noticeable 

 however that, according to several trials recorded by Messrs Sutton, the 

 variety Gladstone threw no rogues in our sense, though this variety has 

 pods markedly curved. Of other curved types we have no evidence. 



From the indications given we incline to think that the joroduction 

 of rogues is a consequence of some instability connected with great 

 lateral extension of the parts. 



From the genetic evidence' it is clear that in order to influence the 

 somatic structure beyond the juvenile stage, or to appear in the germ- 

 cells, the character, whatever it is, must' be introduced fi-om both sides 

 of the parentage. 



In the business of harvesting we have had the benefit of much 

 assistance from many workers at this Institution, to whom our thanks 

 are due. During 1914 also, Miss Ida Sutton, one of our Minor Students, 

 took jjart in recording and generally in the experimental work. 

 ' The exceptions must be remembered.
