*These two results were obtained in the years 1917 and 1918. This variety was not in the 1919 series 

 and the seed did not germinate well in 1920. 



Two of these strains have become commercial since 1918. The results 

 show that the check (Michigan-two-row) has found only one worthy competi- 

 tor and this is a strain picked out of a variety (Crawford) that varied consid- 

 erably in jdelding power. On the other hand the Michigan Black Barbless 

 has not proven to be a good yielder in these tests, but farmers like it because 

 it is smooth awned. The Cra^A^ord has two strains with awns that are not 

 sharply barbed, being considered simply rough aw^led. These are No. 72213 

 and No. 72209. All other .strains in this test have barbed awns. It is noted 

 that more than half of the above varieties and all of the highest yielders are 

 two-rowed barleys. 



The future interest in barley breeding seems to center around a cross be- 

 tween the Michigan-two-row and Michigan Black Barbless. This cross was 

 made in 1916, and since that time has been running in the progeny selection 

 plats. The result is that a number of white smooth awned types have been 

 obtained. Some of them are two-rowed and some of them six-rowed. As 

 soon as they can be increased they will be placed in varietal series. If a good 

 yielder can be found among them it will be increased. Such a barley will 

 easily take preference above all barbed barleys. 



A bean bulletin is at the printer's and will be in the hands of growers before 

 this report is printed. It reviews the bean breeding work to date. The 

 results show that the old strains of Robust now in the hands of growers have, 

 as a rule, been so badly mixed that many of them are no more productive 

 than the common varieties. 



A new strain of Robust (No. 40520) will be introduced under the name of 

 the Improved Michigan Robust in 1922. It is now being increased for that 

 purpose. The results show that it yields one and st half times as many beans 

 as the Early Wonder, on an average of three years' tests at the Michigan Agri- 

 cultural College. 



The future of the bean breeding work seems to center around varieties that 



are resistant to anthracnose and blight. The former type of resistance is 



coming from a cross made in 1916, and the Improved Michigan Robust is 



considerably resistant to blight, enabling it to retain a much larger portion
