from the type portion of the target group ; all 



were graded and pronounced to be of Abbassi type, besides 

 having the Abbassi colour. The seed from these nine 

 plants was sown in nine adjacent plots, and in seven out 

 of the nine the strains were pure as far as branching 

 and leaf -form characters were concerned. None of these 

 seven kinds in the least resembled one another, and all 

 were more dissimilar than the plot of Abbassi had been 

 from other Egyptian varieties in the previous year. From 

 those plots with peculiarities which showed up well in 

 the camera, photographs were made of average plants; 

 and, striking though these differences appear in the 

 photographs, they decidedly minimize, rather than 

 exaggerate, the differences actually shown.

differences from one site to another. It follows from
