376 Report of the Horticulturist of the 



Eldorado pollinated with Catawba. — Four clusters wliich were 

 tested were rated, respectively, 0, 0, 0, 2. Average rating 0.5. 



Catawba is a self-fertile variety. In these tests self-fertile 

 sorts have generally been good fertilizers for the self-sterile kinds. 

 Xo explanation is offered for the exceptional results which fol- 

 lowed the pollination of Eldorado with Catawba. There seems 

 to be no good ground for the opinion that the Eldorado pistils 

 were defective, for the clusters on the tested vines which were open 

 to cross-pollination were unusually well formed, and some excellent 

 clusters were also obtained by fertilizing Eldorado with Worden 

 and Niagara. Catawba fertilized other self-sterile sorts very 

 successfully in these tests, with the exception of Salem. ^ 



Eldorado pollinated with Worden. — Eive clusters which were 

 tested were rated respectively 20, 60, 75, 75, 95. Average rating 

 65. 



Eldorado pollinated with Niagara. — Five clusters which were 

 tested were rated respectively 50, 60, 75, 95, 100. Average rat- 

 ing 76. 



Eldorado as a fertilizer. — Eldorado was tried as a fertilizer on 

 two self-sterile sorts, Brighton and Herbert, under which varieties 

 will be found the details of the tests. 



EUMELAN. 



Eumelan self-pollinated. — In 1892, 10 clusters of Eumelan 

 which were kept covered during the blooming season, gave no 

 fruit. In 1895, 9 clusters which were likewise tested gave no 

 fruit. In 1893, 3 clusters which were likewise tested were rated 

 respectively 0, 0, 4. Average rating 1.3. In 1899, 1 cluster 

 which was likewise tested was rated 20. In view of all these 

 tests it appears that with rare exceptions Eumelan fails to set 

 any fruit when self-pollinated, and it may be classed as prac- 

 ticallv self-sterile. 



6 Salem fertilized by Catawba, rated 4, but only a single cluster was tested 

 so that no conclusions can be drawn till the results are verified by further in- 

 vestigation.
