Data were obtained from 41 field experiments located throughout the Island. From the whole group of varieties tested, 20 were selected for evaluation of their sucrose production at harvesttime. The data were grouped according to three broad climatic areas, namely, humid, subhumid, and semiarid. Certain varieties were observed to produce better sucrose yields in a given climatic region, but in general, there were no significant differences among climatic regions for most varieties. P.R.'s 908, 907, 902, and 905, M.'s 330 and 28, and C.A.'s 38-102 and 38-74 produced the highest sucrose yields at harvesttime. The superiority in this respect of M.'s 336 and 28, and P.R.'s 907, 902, and 905 has been definitely established. Other promising varieties need further testing. Most of these canes yield more total sugar than the standard commercial P.O.J. 2878 and B.H. 10-12 canes, which cover more than 80 percent of the total land area where sugarcane is grown in Puerto Rico. The important bearing of seasonal variation on sucrose content of varieties is discussed. Seasonal differences in the performance of individual varieties have proved to be much greater than differences encountered between varieties in the same season.
