POLLINATION AND CROSS-FERTILIZATION IN THE JUAR PLANT 



Cross XI. 



In 1911 amongst the white grained plants of Cross No. V, two lines were 

 found containing plants with long and sliort glumes respectively, the 

 proportion of which was very nearly 3 short : 1 long. It was therefore 

 obvious that the parent heads from which those lines were sown were 

 heterozygous for the long and short glume characters respectively.

Nilwa {short glume). 



Cross XII. 



In 1911 a short red juar was observed in the pure line of white Galgalya. 

 This on resowing split into four types of heads — red short, red long, wliite 

 short, and white long. The original short red was therefore heterozygous for 

 two pairs of allellomorphs, viz., red and white in the colour of the grain, and 

 shortness and longness in the length of the glume.
