But another cross gave a still higher result. Among 

 a native variety called Kotte wheat was found a plant 

 which was evidently a natural cross between the'native 

 and one or other of the imported high yielding varieties. 

 With good yield this plant combined strong winter 

 resistance and exceptionally strong rust resistance, but 

 was inclined to lodge, late in ripening, and had grain 

 of poor quality. Consequently it was of no economic 

 importance. It was crossed, however, with Grenadier II 

 — Extra Squarehead II being not yet available— and, 

 from the descendants, a variety was selected of good 

 quality whose yield was even higher than that of Extra 

 Squarehead II. When Professor Nilsson-Ehle's paper 

 was published, this new variety was designated by a 

 number only, (0801), but it had been tested over a 

 period of five years, and, if we set down the average 

 yields of itself and its parents, together with similar 

 figures for Extra Squarehead II and its parents, we 

 shall see the advance it made :
