proved till the results of crosses between chlorotic and green 

 plants are available. A number of crosses made in Dacca 

 last season were unfortunately destroyed in the cyclone, but 

 the work is being repeated this season both in Dacca and 

 Pus a. 



A form of chlorosis very similar to that in jute has been 

 found to be prevalent in rahar (Cajanus indicus) in Pusa, 

 and selections have been made for the purpose of further 

 study. It is proposed to make further search amongst other 

 crops. Chlorotic plants have been frequently noted in the 

 species of Phaseohis cultivated in East Bengal, and it is 

 possibly a fairly frequent phenomenon.
