332 REPORT OF THE CONFERENCE ON GENETICS 
red cane. The canes of two holes of this cross were recumbent in habit 
of growth, taking somewhat after B. 1376, while the canes of the other 
hole were upright—a characteristic of B. 1529. The canes were all above 
average size, therefore resembling B. 1876 rather than B. 1529, which is 
a thinnish cane, but they possessed internodes which resembled closely 
those of B. 1529. Two-thirds of the canes also resembled B. 1529 in 
that they had leaf-sheaths which were somewhat adherent to the stem. 
Cross 2.—B. 38289 @ x B. 1529 ¢=B.H.15: Colour yellowish-green ; 
habit of growth upright; internodes roundish; eyes round; dried leaf- 
sheaths somewhat adherent. 
The canes of this cross died early through the effects of the excessive 
drought that was experienced, and therefore the characteristics could not 
be closely followed. 
Cross 3.—B. 3289 2 x B.1855 ¢ = B.H. 18: Colour yellowish-green ; 
habit of growth slightly recumbent; internodes variable, but generally 
roundish ; eyes round; dried leaf-sheaths adherent ; disease-resistance fair. 
The canes of this cross were drought-resistant, and resembled in colour 
and habit of growth B. 3289, in the shape of internodes B. 1355, but 
differed from both parents in possessing adherent leaf-sheaths. 
Owing to the unfavourable season during this last year, it was thought 
advisable to cut up all the canes available from these crosses and not to 
submit any of them to chemical analysis, and therefore it is impossible at 
present to say what will be the commercial value of these canes. During 
this next year the characters of the hybrids will again be closely followed 
and recorded, in order to see if any of them are variable. 
SELF-FERTILISED SEEDLINGS. 
In 1904 several arrows of the better varieties were also bagged to 
obtain self-fertilised seedlings, in order to investigate, if possible, some 
of the dominant characteristics of our different varieties of sugar-cane. 
B. 1529 gave 42 seedlings, which showed the following variations : * 
Weight of canes per hole . extremes . O51b.to 47 Ib. 
Saccharose per gallon . : if 1256 lb. ,, 2°398 lb. 
Glucose per gallon : 5; ‘028 lb. ‘139 lb. 
It also showed that its red dele: was a recessive Ehancie a fact 
which is borne out by the seedlings obtained by the cross between it and 
B. 1876. It might also be thought that its upright habit is also recessive, 
for the self-fertilised seedlings presented habits recumbent to upright in 
the ratio of 3 to1. One of its dominant features is the inherent rich- 
ness of its juice, a fact already noticed when compared with the analysis 
of the juices of other seedlings grown under similar conditions. 
B. 1876 gave 27 seedlings that also varied considerably, as may be seen 
by the following table : * 
Weight of canes per hole . extremes . 8lb.to 50 Ib. 
Saccharose per gallon. : 35 5 A196 Ab, 5) 2015 sib:

* The figures were obtained from Professor J. P. d’Albuquerque, Chemist in 
Charge of Sugar-cane Experiments, and Mr. J. R. Boyell, Agricultural Superintendent, 
Barbados.
