1922.] SUGAR CANE EXPERIMENTS, 1920-22. 77 



Owing to the large number of promising seedlings obtained 

 from the 1920 lot it has been found necessary to adopt a much higher 

 standard than that of previous years. No seedlings, whose juice 

 contained less than 1*700 lb. sucrose per gallon, have been retained 

 for further trial unless the stools were exceptionally large or the canes 

 very fine specimens. It will be seen from the above that the bulk of 

 the good seedlings were raised from the Bourbon, H.? and M.P. 55. 



When the stools of these selected varieties have grown up, 

 cuttings will be planted in plots about October-November and 

 grown in competition with standard varieties, such as B. 156, 

 Badilla, Ba. 6032 and B.H. 10 (12). From the results obtained a 

 further selection will be made, only those varieties which give very 

 good results will be kept and planted in larger plots. 



TRINIDAD SEEDLINGS RAISED IN 1919. 



Ou of the seedlings raised in 1919, fifty-eight were selected from 

 their combined field characters and analytical results for further trial 

 in plots. Fifty-one of these were planted out, in Field 15, on 

 November 3, 1921, the other seven were discarded as the stools 

 showed signs of disease or had died out. 



Re-selection of seedlings raised in 1919. 



As stated in a previous report (^) seedlings which do not grow 

 into sufficiently large stools, during their first year's growth, to 

 warrant their being tested, are allowed to grow into ratoons after the 

 canes have been cut out. Fifty of the 1919 seedlings grew into fair 

 stools as ratoons. The canes were accordingly sampled and the 

 juice analysed on May 2 and 3, 1922, when they were approximately 

 twelve months old.
