to change significantly the weight of accumulated roots.
Home-grown clover seed may relieve shortage on many Pennsylvania farms,
E. J. ANDERSON, F. V. GRAU, H. W. HIGBEE, and J. K. THORNTON (Pennsylvania
Sta. Bul. 446, Sup. 3 (1944), pp.  + 1, 10, illus. 4).-Economical yields of seed
of alfalfa and clover appeared possible if honeybees are provided to work the
blossoms. Under such conditions from 2.5 to 5 bu. per acre of clover seed and
3 to 6 bu. of seed of variegated alfalfa have been produced near the station.
Differences in seed setting were noted among clover strains and in caged v. openfield
clover. A hammer mill used to grind feed on farms, supplemented by a
farming mill, hulled and cleaned the seed. Seeds of timothy and orchard grasses
were harvested with reduced losses from shattering by modifications of cereal
harvest methods, involving use of a binder and subsequent threshing with a combine.
Hibridos comerciais de milho [Commercial corn hybrids], C. A. KRUG, G. P.
VIEGAS, and L. PAOLIERI (Bragantia, 3 (1943), No. 11, pp. 367-552, illus. 65; Eng.
abs., p. 551).--Report is made on a corn improvement project, 1932-42, including
descriptions of basic material, details of methods used, annual results, and adaptation
of exotic lines, mainly from the United States. Up to 1941-42, 133 (3.5 per
cent) of more than 3,700 hybrid combinations significantly outyielded control varieties
by from 7 to 92 per cent in three different ecological zones in the State of
Sao Paulo, Brazil. Production of hybrid seed corn on a commercial scale was
Successful corn hybrids must suit the environment where grown, L. L. HUBER
(Pennsylvania Sta. Bul. 446, Sub. 3 (1944), pp. 4-5, 7, illus. 3).-The need for
corn hybrids that are suitable for particular environments is illustrated by comparative
yields, maturity, moisture contents, lodging, and other agronomic characters
tabulated from performance tests for a number of open-formula hybrids and openpollinated
Niacin in maize, P. R. BURKHOLDER, I. MCVEIGI, and D. MOYER (Yale Jour.
Biol. and Med., 16 (1944), No. 6, pp. 659-663).-Assays of mature corn of 233
strains and hybrids showed niacin (values expressed as micrograms per gram of
air-dried mature grain) to average for yellow corn 21.4 (range 11.3-36.3), white
20.1 (12.7-29.4), sweet corn 34.6 (18.2-62.1), and popcorn 17.4 (7.9-21.6). Preliminary
data obtained for inbred lines and hybrids between them suggest that
genetic factors control ability of the corn plant to store niacin. Available data
indicate that hybrids between high and low niacin lines may have an intermediate
content, and those hybrids with the largest amounts of niacin come from parental
lines high in niacin. The fact that different strains of both sweet corn and field
corn, grown adjacent in the same soil at the Connecticut [New Haven] Experiment
Station, contain widely different amounts of niacin points to the importance of
inheritance in determining vitamin content.
"In view of the obvious variation of vitamin content in different genetic strains
of maize produced in different geographical regions, it is suggested that corn
breeders, and those who process and distribute corn products, may do well to
consider the selection of better types of maize for use by people whose dietary is
conducive to pellagra and other deficiency diseases."
