duced from seed of D-lOf).' This is a dark* greenish-red 1o purple 

 cane, usually reclining in liabit. witli buds before expanding semi- 

 elliptical in shape. Many of the seedlings idainly sliow some or all 

 of these characteristics, while the resemblance as to color is ("S])ociall>' 

 noticeable. 



A great majority of the seedlings of T-77 are very imicli like 

 this variety in color and habit, and resemble it more or less as to 

 the form of the bud. 



Out of thirty-four seedlings produced in 1916 from 1)-31:7. a 

 light-colored cane, only two were of a darker shade than the parent, 

 and seventeen of them showed spots on the internodes more or less 

 like the characteristic spots on the parent variet3^ 



The B-109 seedlings produced in 1916, one bundred and ninety- 

 two in all, were all yellowish-green in color, being like tlu^ parent 

 variety in this respect. They also resembled the parent more or 

 less as to the shape of the internodes and tlie ))uds. One seedling 

 was darker green than the parent variety and had a tinge of red 

 on the upper internodes ; one was a shade dai'ker green. l)ut without 

 the reddish tint; three were greenish-yellow like the parent, but 

 tinged with red on the upper internodes; three were the same color 

 as the parent with the addition of bi-ownish-i-ed blotches on the 

 stalks. 



Other variations occurred among these seedlings as follows. Two 

 were markedly glaucous; one had especially prominent buds; one 

 had extremely short joints ; two had many adventitious roots ; one 

 had especially thin stalks; one was very thick-stalked. There was 

 also a great difference among these seedling as to vigor of growth. 

 Those growing in the area of bettei- soil wei'e taUer and of lai'ger 

 girth, while a majority of those on |)oori"r soil appeared more or 

 less stunted, some of them producing almost no stalks. 



Out of three hundred and sixty-six seedlings from the variety 

 D-448, which is a red cane, two hundred and twenty-one or sixty 

 per (;ent, showed redness on the stalk, though some in a less degree 

 than the j^ai'ent variety. Thirty-four per cent wei-e i(>d all over 

 the stalk, but some were a lightei- i-ed tlian Ihe pai-ent i-ane. Twel vi- 

 per cent were as dark or dai'kei- Ihaii the pai-eiit. 



'Those seedlings and tliose of snli.seiiiicnt iiisl.iiKis i-ilcil, cMcijt w liere cro.ss-jxjIliuiitiDn 

 is indieiited. were raised frdni seed from (ipen-pollinatefl tassels. Kor that reason the purity 

 of the p()llen_can not he guaranteed. However, it does not seem probahle that sugar-cane 

 pollen is carried more than a short distance )>y the wind. It has no special adaptation for 

 being transported and is soft and delicate. Iii some cases ob.served the stigmas of the florets 

 were in close contact with the dehiscing anthers. The anthers are shed in great nunil)ers, 

 and possibly they pollinate other florets as they fall. For these reasons it seems probable that 

 the tassels in the center of a field of a pure variety are. without exception, pollinated by pol- 

 len of the same variety. The similarity of the seedlings in many cases also tends to verify thiK 

 belief. It is planned to hag tassels for self-- ollination to obtain furthei- data on this point.
