STATE BOARD OF AGRICULTURE. 



All members of the Michigan Crop Improvement Association, who plant 

 rye in the fall of 1921, -will be required to secure their seed from head selected 

 stock grown by these growers. All certified Rosen sold in 1922 mil there- 

 fore be only two generations removed from carefully selected Rosen. 



MANITOU ISLAND ROSEN. 



The entire acreage planted to rye on the South Manitou Island is now 

 planted to certified Rosen. The South Manitou is an island of approxi- 

 mately 7,000 acres, located 10 miles off shore directly west of the Leelanau 

 Peninsula. From 70 to 120 acres of rye is grown annually on the island. 

 For the past two years head selection work has been carried on by the Mich- 

 igan Agricultural Experiment Station. 



During the coming fall the entire acreage of the island will be planted 

 from seed two seasons removed from careful head selection. This year's 

 head selected plat will be increased on a 10-acre field and next year all who 

 grow rye on the island will get their seed from this increase. This course 

 will be followed for a number of years. 



Owing to the isolated position of the island it is easily possible to prevent 

 common or other varieties of rye from being grown. 



Figure No. 7. The South Manitou Island off the shore of the Leelanau Peninsula. The 

 entire rye acreage of this Island is now planted to selected Rosen rye, and will serve as a source 

 of high-grade seed, produced under isolated conditions. 



Growers on the island have formed an island Chapter of the Michigan Crop 

 Improvement Association. By careful head selection and field inspection 

 it is expected that the South Manitou Island will furnish a source of excep- 

 tionally pure, high yielding rye. 



Thefirst prize offered for rye at the 1920 International Grain and Hay 

 Show was won by a South Manitou Island rye grower.
