a The yields of the different progenies are strictly comparable because the rows were of uniform length 

 and the stands were all perfect. 



b Only those selections from each variety are here included of which the progenies in 1909 gave yields of 

 seed and of total dry matter above the average for the progenies of all the selections made in 1908 of that par- 

 ticular variety. 



c Including selections the progenies of which yielded low in 1909 and were hence excluded from the 

 preceding showing. 



Some interesting results are shown in the millet-breeding work as 

 recorded in the above table. It will be noted in the record of averages 

 that the Kursk is the highest yielding variety in the progeny rows 

 grown in 1909, both in total weight of plant and weight of seed. 

 Kursk is considerably ahead of any other variety in yield of seed 

 though the Common variety exceeds it in proportion of seed to straw. 



It will also be noted that the yields of seed and straw of the proge- 

 nies, in general, correspond rather closely with those of the respective 

 mother plants. This is especially marked in the Kursk and Common 

 varieties. For example, in the Kursk variety, seven selections are sepa- 

 rately listed in which the progeny of each yielded above the average of 

 all rows. As shown in Table VI, the selected mother plants all yielded
