Seed and lint characters. 
(1) The ginning percentage of the kapas is hereditary, but there are 
variations from season to season due to reasons other than seed 
weight. 
; (2) The seed weight is hereditary. 
The evidence on which these statements are based is as follows :— 
1. The shape of the boll is hereditary! In ordinary Goghari cotton, as 
grown, there are very great variations in the type of boll. Some of these 
variations are shown in Plate V, fig. 2, which represents the character of the 
bolls in a number of strains (pure) which we have isolated and each of which 
is described in the next section of the present paper. These may be indicated 
as under :-— 
A. Spherical in shape and large. 
B. (1) Long and tapering with smooth surface. 
(2) Tapering with rough surface. 
C. Spherical, but small. 
EK. Intermediate in type between A and B. 
The original types, from which these strains have been developed, were 
selected in 1914-15, on the basis of these very boll characters. On growing, 
however, they were found each to yield plants with bolls of the most varying 
kinds, more than 55 per cent. in the case of types A, B, and C being rejected 
in the first year’s crop. By careful selection, however, plants have been 
obtained which breed entirely true to this character. In the strains with 
boll characters represented by A, plants had been evolved by 1918-19 whose 
progeny gave an absolutely uniform series of spherical bolls, breeding true 
year after year. Similarly in strains with the characters of B and C, the same 
stage was reached in 1916-17, while in those with characters of HK, the plants 
bred true as to the type of boll in 1917-18. 
2. The size of the boll and the quantity of kapas per boll are hereditary. 
In an ordinary collection of bdlls of Goghaii cotton the variation in size 
is very great, even in the same season. Some idea of this can be given by 
figures for a large number of bolls from our own plots, which are of course more 
uniform than the types in ordinary fields. The size will perhaps be best 
indicated by the number of bolls required to give one pound of kapas. This 
varied in two different years as follows :— 
1917-18. 181 to 247 ora variation from the mean of 15:4 per cent.
