Variety Descriptions & Catalog Codes
Variety Descriptions by CR Lawn
• Seek selections suitable for your use: home consumption,
market or CSA.
• Be observant and aware: farming and gardening are more art
• Microclimate, soil type and cultural practices greatly affect
• Marketers: trial new varieties on a small scale before fully
Disease Tolerance & Resistance - As a guide
to growers we include information provided by our suppliers. These
are not guarantees.
• Even tolerant or resistant cultivars may be harmed in unusual
• Actual field performance depends on climate, weather and
cultural practices which we cannot control.
• Many older cultivars, though unrated for disease tolerance/resistance,
have proven adapted to a variety of conditions.
Following are abbreviations that appear after some variety descriptions.
A number after the abbreviation indicates which race of pathogen:
||Alternaria Leaf Spot
||Alternaria Stem Canker
||Bacterial Leaf Spot
||Bacterial Soft Rot
||Common Bean Mosaic Virus
||Cercospora Leaf Spot
||Cucumber Mosaic Virus
||Curly Top Virus
||Grey Leaf Spot
||Lettuce Mosiac Virus
||Maize Dwarf Mosiac Virus
||Northern Corn Leaf Blight
||NY 15 Mosaic Virus
||Pea Enation Mosaic Virus
||Pea Leaf Roll
||Papaya Ring Spot Virus
||Southern Corn Leaf Blight
||Septoria Leaf Spot
||Tobacco Mosaic Virus
||Common Wilt race 1
||Watermelon Mosaic Virus
||Zucchini Yellows Mosaic Virus
OG after cultivar name = entire lot is certified-organic
ECO after cultivar name = entire lot is sustainably
BD after cultivar name = entire lot is biodynamically
PVP = Plant Variety Protected. Unauthorized propagation
of the seed is prohibited. The use of PVP in the catalog is for
informational purposes only and in no way constitutes an endorsement
by Fedco of plant patenting.
AAS = All-America Selection.
indicates cold-hardy through
at least part of the Maine winter.
= a variety introduced
by Fedco followed by the year first offered.
• Open-pollinated varieties will grow true
to type when randomly mated within their own variety. Provided your
plants have been properly isolated from different varieties of the
same species, seed saved from these plants will breed true.
• Hybrid varieties are those produced from
the crossing of two different inbred lines. Seed saved from
hybrid varieties will not breed true in the next generation.
• Amongst open-pollinated plants, self-pollinated
(selfers) usually reproduce by using their own pollen. Crossers
usually reproduce through the transfer of pollen from one plant
to a different plant of the same species.
• Botanical nomenclature goes from the general to the specific.
Plants are classified into kinds by genus, species,
and variety. In Cucurbita pepo Sweet Dumpling,
Cucurbita is the genus, pepo is the species and
Sweet Dumpling is the variety.
We include supplier codes for each variety. Varieties
with more than one supplier may have two or more codes. We code according
to our best information at press time. When seed is short we must
sometimes change suppliers later in the season. With notable exceptions,
we generally choose varieties based on their merits rather than on
our supplier preferences. We do not offer genetically engineered varieties,
although we purchase from corporations engaged in genetic engineering.
Use the supplier codes to help you make your own choices about whom
you are supporting and which varieties are best for your garden or
farm. Codes are as follows:
Small seed farmers including Fedco staff.
Family-owned companies or cooperatives, domestic and foreign.
Domestic and foreign corporations not part of a larger conglomerate.
Multinationals not to our knowledge engaged in genetic engineering.
Multinationals who are engaged
in genetic engineering.
Heldover Seed - Like most other seed merchants,
we carry over stock from one year to the next, in any given season
between 10–30% of offerings. We test all such lots for viability
and discard any in doubt. Last year we identified some varieties
where all seed was held over and provided germ-test results for
them. This year’s listings are more comprehensive. We think
you should know as much as possible about our seed. Heldover seed
is not necessarily inferior to fresh seed; we have confidence in
all lots we offer. We commission two-year productions of some varieties
to decrease our growers’ costs, increase their efficiencies
and improve their isolations.
Optimal Germination Guide - Sowing seeds at sub-optimal
temperatures is the most common cause of failure. We include information
in some headers about ideal germination temperatures, taken and
extrapolated from tables in Knott’s Handbook for Vegetable
Growers ISBN 0-471-73828X and The New Seed-Starters Handbook by
Nancy Bubel, ISBN 0-87857-752-1.
