The above ratios were confirmed by the result obtained in F,. The 
actual numbers are given in Table 33. 
The coloured stigma, purple awn and glume, self purple palea, and striped 
leaf-sheath are inherited together. According to Hector (1916), 2 the Indian 
varieties studied at Ducca, may be classified as follows : 
(1) Leaf-sheatlis, apiculus of glumes, and stigma coloured. 
(2) Leaf-sheatlis and apiculus of glumes coloured, but stigma colourless.
