42 CROSSBKEEDING CORN. 



among the highest yielding in the three tests, the Dan Patch X Chis- 

 hohn was not in the test at Waco, but at Sherman and at Corsicana 

 it ranks among the highest }delders. These crosses also ranked weU 

 as regards percentage of increased yield over better parent. 



Apparently, then, there are some varieties that combine well and 

 their crosses mil give decidedly increased yields; while the crosses 

 of other varieties either show no improvement in yield, or an actual 

 decrease. As no method is known of selecting the varieties the 

 crosses of which can be depended upon to give increased jdelds, the 

 importance of testing experimentally all crosses before growing 

 them commercially may be readily appreciated by the farmer or corn 

 grower who has in mind the betterment of his general crop by such 

 methods of breeding. 



TESTS AT STATESBORO, GA. 



VARIETIES USED IN THE EXPERIMENTS. 



ALDRICH PERFECTION. 



Aldrich Perfection was obtained from a field near Barnwell, S. C. 

 This variety is not very uniform in t^'pe, but has a large, deep, char- 

 acteristic kernel. The kernel is very irregular in shape and gives 

 the ear a very rough appearance. The variety is grown near Barn- 

 well on very sandy land. As grown at Statesboro, it seemed poorly 

 adapted the first year and the market quaUty was poor. During 

 the second year it seemed better adapted and the market quaUty was 

 fair. 



COCKE PROLiriC. 



Cocke Prolific for this work was obtained from the North CaroUna 

 experiment station. The type showed much variation, but the vari- 

 ety has a characteristic appearance. As grown at Statesboro, the 

 ears were fairly sound, but were seriously damaged by weevils. The 



adaptability was about the same both years. 



I 



MARLBORO PROLIFIC. 



Marlboro Prolific was selected from a farm near Cheraw, S. C, 

 where it has been grown for many years. The type of ear is not 

 very uniform, but it has a characteristic appearance. The native 

 soil of this variety is sandy, wdth sandy clay subsoil. As gi'own at 

 Statesboro, Marlboro Prohfic seemed to produce fairly well both 

 years. The grain was seriously damaged by weevils, otherwise it 

 was in good condition.
