I. INTRODUCTION. 



The investigations described in this paper form part of the 

 work undertaken at Pusa during the years 1905 to 1912 in connec- 

 tion with the improvement of Indian wheat. The earlier practical 

 results and those dealing with classification are to be found in 

 former papers. The present account deals only with the informa- 

 tion obtained on the laws governing the inheritance of the various 

 characters in wheat and with the gametic factors which are in- 

 volved in these characters. 



The results relating to the red colour of the grain, in which the 

 occurrence of several factors was demonstrated, were obtained 

 some years ago and were about to be published when the admirable 

 investigations of Nilsson-Ehle 1 at Svalof were made public. This 

 information was in consequence held over until the experiments 

 dealing with bearding and felting could be included. The results 

 obtained at Pusa both confirm and extend the work of Nilsson-Ehle
