Seed Saving - Beginner

Seed Saving - Beginner


These vegetables offer the beginning seed saver the best chance for successful seed saving. They produce seed the same season as planted and are mostly self-pollinating, minimizing the need to be mindful of preventing cross-pollination.

Bean - Phaseolus vulgaris
PLANT: Although, ideally, different varieties should be separated by 150 feet or another crop flowering at the same time, we rarely observe cross-pollination even when two varieties are grown next to each other.
FLOWER: Beans produce perfect, self-pollinating flowers. Cross pollination by insects is possible but rare as pollination occurs before the flower opens. Because the anthers are pushed up against the stigma, automatic pollination is assured when the anthers open.
SELECTION TRAITS: Most commercial breeders favour bush varieties which can be mechanically harvested and fibrous bean pods which hold up during harvest and shipment. Pole varieties are more suited to small, home gardens because they produce more beans in a smaller space. Because vines are off the ground beans are easier to pick and away from the settling cold air of unexpected frosts.
Plant growth: Pole type growth, D; Bush, r. Pod edibility: Little or no fiber, r; Stringless, r .
Seed colour: White seeded varieties are better for canning because seed colour doesn't affect canning liquid, r; Colored, D. Pod,
foliage and flower colour: Purple, D.
HARVEST: Allow pods to dry brown before harvesting, about six weeks after eating stage. If frost threatens, pull entire plant, root first, and hang in cool, dry location until pods are brown.
PROCESS: Small amounts of pods can be opened by hand. Flail larger amounts. Remove large chaff by hand or fork. Winnow remaining particles.


Lettuce - Lactuca sativa
PLANT: Separate varieties flowering at the same time by at least 20 feet to ensure purity.
FLOWER: Lettuce produces perfect, self-pollinating flowers. Each flower produces one seed. Flowers are grouped in little heads of 10-25 flowers all of which open at once for as little as 30 minutes. Anthers are fused together into a little cone that completely surrounds stigma and style. Style is pushed up through anther cone and is coated with its own pollen. Note: Mature head lettuce may need a slit (two or three inches deep) across the top to encourage flowering.
SELECTION TRAITS:
Leaf colour: red, D. Leaf colour is controlled by at least two genes with a number of variations possible. Generally, hybrids produced by crossing red and green varieties result in red offspring.
Leaf shape: no lobes, D; oak leaved, r. Seed stalk formation : bolt resistance, r;
Seed colour: white seeds, r; black seeds, D.
HARVEST: Some outside leaves can be harvested for eating without harming seed production. Allow seed heads to dry 2-3 weeks after flowering. Individual heads will ripen at different times making the harvest of large amounts of seed at one time nearly impossible. Wait until half the flowers on each plant has gone to seed. Cut entire top of plant and allow to dry upside down in an open paper bag.
PROCESS: Small amounts of seed can be shaken daily from individual flowering heads. Rub with hands to remove remaining seeds. If necessary, separate seeds from chaff with screens.

Peas - Pisum sativum
PLANT: Ideally, different varieties need to be separated 50 feet or with another crop flowering at the same time. However, in the cool regions of the Rocky Moun tains, we rarely observe cross-pollination even when two varieties are grown next to each other.
FLOWER: Peas produce perfect, self-pollinating flowers. Cross-pollination by insects is possible but rare because pollination occurs before the flower opens. Because the stigma does open before pollen is ready crosses theoretically could occur.
SELECTION TRAITS: Most commercial breeders prefer bush varieties with pods that ripen simultaneously in order to facilitate commercial harvesting. Tall varieties produce more peas in small, home gardens.
Plant Growth : tall, D; bush, r.
Seed Shape: Round seeds germinate better in cold weather, D; w rinkled seeds, r.
Pod Edibility: lack of fibers on the inside of the pod, r.
Pod shape: round, D; flat, r.
HARVEST: Allow pods to dry brown before harvesting, about four weeks after eating stage. If frost threatens, pull entire plant, root first, and hang in cool, dry location until pods are brown.
PROCESS: Small amounts of pods can be opened by hand. Flail larger amounts. Remove large chaff by hand or fork. Winnow remaining particles.

Pepper - Capsicum annuum
PLANT: Most home gardeners will get satisfactory results if different varieties are separated by 50 feet and another tall, flowering crop. New studies from New Mexico State University show more crossing than was previously thought. We recommend at least 400 feet between varieties to ensure absolute purity.
FLOWER: Peppers produce perfect, mostly self-pollinating flowers. Solitary bees will pollinate if a more desirable pollen is not available in the area.
SELECTION TRAITS:
Flavor: Hot, D
HARVEST: Harvest mature, fully-ripe peppers for seed. (Most bell peppers turn red when fully mature.) If frost threatens before peppers mature, pull entire plant and hang in cool, dry location until peppers mature.
PROCESS: There are two methods, dry and wet, to process pepper seeds. The dry method is adequate for small amounts. Cut the bottom off the fruit and carefully reach in to strip the seeds surrounding central cone. In many cases, seeds need no further cleaning. To process the seed from large amounts of peppers, cut off the tops just under the stem, fill a blender with peppers and water and carefully blend until good seeds are separated and sink to bottom. Pepper debris and immature seeds will float to the top where they can be rinsed away. Spread clean seeds on paper towel and dry in cool location until seed is dry enough to break when folded.

Tomato - Lycopersicon esculentum
PLANT: Separate varieties with short styles (most modern varieties) by at least 10 feet. Varieties with long styles (heirlooms and older varieties) need at least 100 feet to ensure purity. If solitary bees are prevalent, separate all varieties at least 100 feet and place another flowering crop between.
FLOWER: Tomatoes produce perfect, self-pollinating flowers. Anthers are fused together into a little cone that rarely opens until pollen has been shed and the stigma pollinated. (Older varieties with wild tomatoes or L. pimpinellifolium in their genetic ancestry may have stigmas that stick out beyond the cone containing the anthers. Varieties with this trait can be identified by looking closely at mature flowers and need to be treated accordingly.)
SELECTION TRAITS: Tomato is the most popular vegetable in America and hundreds of the genes have been mapped. Those of immediate importance for home gardeners include:
Plant size: Determinate varieties, r; b ush varieties, r; dwarf varieties, r.
Leaf Shape : Potato-type leaves, r. Disease resistance : Leaf mould resistance, r; fusarium wilt, race 1 and race 2, D; verticillium wilt, D; alternaria, D; tobacco mosaic, D; nematodes, D.
Ripening : prevents green shoulders, r; prevents ripening and is found in Longkeeper, r; produces parthenocarpic fruits which do not need to be pollinated. Tomatoes without seeds can be produced in weather too-cold for pollination to take place, r.
Fruit colour - produced by the combination of flesh and skin colours:
red: pink flesh, r covered by a yellow skin, r
pink: pink flesh, r and colourless skin, r
crimson: bright, purplish-red flesh, r and yellow skin, r
purple: bright, purplish-red flesh, r and colourless skin, r;
yellow: yellowish flesh, r and yellow skin, r
white: yellowish flesh, r and colourless skin, r
orange: reddish-orange flesh, D and yellow skin, r
HARVEST: If possible, allow tomatoes to completely ripen before harvesting for seed production. Unripe fruits, saved from the first frost, will ripen slowly if kept in a cool, dry location. Seeds from green, unripe fruits will be most viable if extracted after allowing the fruits to turn colour.
PROCESS: Cut the tomato into halves at its equator, opening the vertical cavities that contain the seeds. Gently squeeze out from the cavities the jelly-like substance that contains the seeds. If done carefully, the tomato itself can still be eaten or saved for canning, sun-drying or dehydrating.
Place the jelly and seeds into a small jar or glass. (Add a little water if you are processing only one or two small tomatoes.) Loosely cover the container and place in a warm location, 60-75? F. for about three days. Stir once a day.
A layer of fungus will begin to appear on the top of the mixture after a couple of days. This fungus not only eats the gelatinous coat that surrounds each seed and prevents germination, it also produces antibiotics that help to control seed-borne diseases like bacterial spot, canker and speck.
After three days fill the seed container with warm water. Let the contents settle and begin pouring out the water along with pieces of tomato pulp and immature seeds floating on top. Note: Viable seeds are heavier and settle to the bottom of the jar. Repeat this process until water being poured out is almost clear and clean seeds line the bottom of the container.
Pour these clean seeds into a strainer that has holes smaller than the seeds. Let the excess water drip out and invert the strainer onto paper towel or piece of newspaper. Allow the seeds to dry completely (usually a day or two). Break up the clumps into individual seeds, label and store in a packet or plastic bag.
