crops in G.L.F. territory. To check the performance of 
this seed, the G.L.F. Garden Seed Service carries on an 
extensive quality control program. 
Trial Gardens 
The only effective way to check seed quality is to 
grow the crop under natural conditions and compare it 
with other strains of the same variety. All G.L.F. seed 
is checked in trial gardens and judged by these standards: 
1. Trueness to type. including size, color 
Sand edible quality. 
2. Season‘of maturity and\adaptation to 
‘GL. F. growing conditions. 
3. Wielding ability. 
4. Freedom from off-types and varietal 
mixtures. 
». Resistance to common diseases and. 
im some cases, inseets. 
6. Freedom from seed-borne diseases. 
7. Viability (power to grow) as compared 
with U. 8. standards. 
Laboratory Tests 
Samples of all seed stocks are given purity and germina- 
tion tests in the G.L.F. seed laboratory as a further check 
on their quality. 
Inspection Trips 
G.L.F. seedsmen make regular trips to the western grow- 
ing areas to check on the best sources of garden seed. 
This three-phase quality control program supplies a 
sound basis for making all purchases of G.L.F. Garden 
Seed. 
Stock Seed Production Program 
There is considerable evidence that some seed _ strains 
may lose their adaptation to eastern conditions if grown 
continually in the west. To overcome this difficulty, 
G.L.F. is carrying on a breeding and selection program 
here in the east for producing stock seed of Danish 
Ballhead cabbage, Early Yellow Globe and Michigan 
Yellow Globe onions, French Horticultural beans, Detroit

Heads were grown in 1944, stored during the winter and set in field in 
early April, 1945.

Beets are biennials like cabbage and onions. 
Dark Red beets and Iroquois melons. The stock seed 
produced by G.L.F. is then sent west for multiplication. 
Many of these crops are biennials, which means that 
two years are required from seed to seed. Mature cab- 
bage plants, onion bulbs and beets are stored during the 
winter and transplanted to the field the following spring 
for seed production. The second year’s planting gives an 
additional opportunity to select the best mother plants 
before actual seed growth starts. 
This program assures G.L.F. patrons of stock seed bred 
under eastern conditions and adapted to this climate.
