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 :
