CLASSIFICATION AND DESCRIPTION OF THE 
WHEATS OF THE PUNJAB. 
The material from which our types were segregated consisted 
of 72 plots of wheat at Lyallpur (collected by the Director of Agri- 
culture from all the districts of the province), and also a collection 
of the wheats grown by the cultivators of the Chenab colony. These 
plots were carefully searched in the field during the harvest of 1906, 
and all the constituents of each plot collected. These were then 
examined in the laboratory at Pusa and separated into botanical 
varieties. The same botanical variety was thus often found to 
occur in many plots. 
The botanical varieties were sown at Lyallpur in 1906 as follows : 
the constituents of each variety found in the various plots were 
sown separately from single plants, and in 1907 these cultures were 
carefully examined both for vegetative characters at flowering time 
and also for further agricultural or field characters at harvest time. 
In this way it was found that in many cases the variety was made 
up of several types, in others there was only one type. The types 
were then described and the cultures repeated in 1907. In 1908, 
the types were finally determined in the field from a study of the 
comparatively large plots then available. Twenty-five different 
types were distinguished, the classification and description of which 
are given below. In many cases it was found that the types occur 
all over the province either in partly pure or very mixed culture 
under different names, and that many of the wheats cultivated in the 
new Chenab colonies were brought by the settlers from other parts 
of the province. Many of the wheats commonly grown are with- 
out doubt of a poor character and not very valuable for export pur-
