Jubbulpore hemp grown at Piisa. No differences were observed, 

 and it appeared likely that only one variety of this crop is 

 generally cultivated in the Central Provinces. 



In 1908, our attention was arrested by the marked difference 

 in appearance betw^een the seedlings on a field sown with Central 

 Provinces Sann-hem-p and those in a field sow^n wath the local Sann- 

 hemp. A portion of each was allowed to seed and further differ- 

 ences were noted in the ripe plants. Accordip-gly the seed of a 

 large number of single plants of each of these fields was saved and 

 sown separately in 1909 side by side and under uniform conditions. 

 Observations were also made on a field divided into three parallel 

 strips and sown wnth local seed, seed from the third generation 

 at Piisa-grown Jubbulpore hemp and with seed freshly imported 

 from Hoshangiibad. No differences w^ere observed between the 

 Piisa-grown Jubbulpore hemp and that from Hoshangabad. These 

 proved identical. 



There were marked differences, how^ever, between the local 

 *Say?,n-hemp and that from the Central Provinces, and these differ- 

 ences could be easily traced from the seed to the mature plant. 



The seeds of the two varieties are quite distinct. The seeds of 

 the local ASfmn-hemp are small, shiny and quite black ; those of the 

 Jubbulpore hemp are much larger, duller and bluish black or greyish. 

 The differences in time of germination are equally marked. The 

 larger seeds of the Jubbulpore variety germinate with remarkable 

 rapidity, and the seedlings appear above ground from 12 to 24 

 hours earlier than those of the local variety w^ien both are sown at 

 the same time and under equal conditions. The start gained by 

 the Jubbulpore variety is never lost throughout the whole of the 

 after- development of the plant and the Central Provinces variety 

 is ahvays larger, taller, and earlier than the local. In addition to 

 the speed of germination and of subsequent growth the characters 

 of the seedlings of the two varieties are quite distinct. The aver- 

 age length of the seed-leaves of the local seedlings is 22 mm., that 

 of the Jubbulpore variety 30 mm. On account of this difference 

 the appearance of the two sets of seedhngs is very different. Apart 

 from the size of the seed-leaves, there are other distinctions. The
