Cowpea, Vigna unguiculata (L.) Walp., is a very important legume in the diet of the population of the Amazon. Although it is autogamous, this species has a cross- pollination rate of ≈10%.
Will peas and green beans cross pollinate?
Beans don’t cross with peas or other legumes, but different varieties of beans cross with each other, and different varieties of peas cross with each other. You can plant a row of beans next to a row of peas, but if you have two kinds of peas, separate them by the distance shown above.
Do black-eyed peas cross pollinate?
Black-eyed peas are self-pollinating, though it is best to isolate different varieties of V. unguiculata (including black-eyed peas, southern peas, cowpeas, and long beans) at least 20 feet, if not much farther to avoid unwanted cross-pollination.
Do peas cross pollinate?
Peas are generally self-pollinating and the likelihood of cross-pollinating is low. However, insects do visit pea flowers and can cause crossing. Commercial seed growers recommend a minimum separation of 20m, which is not really practical for the home seed saver, but try to leave as great a distance as possible.
What beans will cross pollinate?
Only beans in the same species are capable of cross-pollinating. So, pole beans (Phaseolus vulgaris) can cross with other varieties of bean in the same species but they cannot cross-pollinate with soybean (Glycine max) which is in a different genus.
Which vegetable crops is often cross pollinated?
Vegetable Cross-Pollination Guide
| Vegetable Crop | Will Cross-Pollinate With |
|---|---|
| Broccoli | Readily crosses with any Brassica oleracea species: Cauliflower, Cabbage, kale, brussels sprouts, kohlrabi, romanesco broccoli, kale, collard greens, broccoli |
| Brussels Sprouts | See: Broccoli |
What will cucumbers cross pollinate with?
Cucumber can cross-pollinate with other varieties of cucumbers in the sativus family. Other plants within the same family may cross-pollinate as well, including plants in the pumpkin, gourd and summer squash families and some winter squash.
Do tomatoes cross pollinate?
Tomatoes don’t cross-pollinate easily because they usually self-pollinate before the flowers open. However, if a bee arrives loaded with pollen from another variety, a cross or hybrid may occur.
Do bush beans and pole beans cross pollinate?
Can they cross-pollinate? The regular Phaseolus vulgaris beans may cross, even pole beans to bush beans or vice versa.
Will yard long beans cross pollinate?
Because yard long beans are in the Vigna unguiculate family, they don’t cross pollinate with common beans (Phaseolus vulgaris) or runner beans (Phaseolus coccineus) that we grow in other parts of the garden. This allows us to isolate varieties and save our own seed without concern about cross pollination.
Do peas cross pollinate with sweet peas?
Although these plants are from the legume family (Fabaceae), garden peas (Pisum sativum) and ornamental sweet peas (Lathyrus odoratus) are of different genera. This usually means they are unlikely to cross pollinate.
Can sweet peas cross pollinate?
Do sweet peas cross pollinate? Sweet peas are self-pollinating – they fertilize themselves whilst the flower buds are still young and haven’t opened.
Is chickpea cross pollinated crop?
Chickpea is a diploid and predominantly self-pollinated legume, but cross-pollination by insects sometimes occurs (Purseglove, 1968). It belongs to the Fabaceae family.
How do you keep beans from cross pollinating?
To prevent cross pollination, you would need to plant different varieties 100 yards (91 m.) or more apart. This is normally not possible in the home garden. Instead, you can select a bloom that you will later collect seeds from the fruit or seedpod.
Does squash cross pollinate?
For example, cross pollination can be seen in the squashes and pumpkins. Summer squash, pumpkins, gourds, and some types of winter squash belong to the same plant species, Cucurbita pepo. All varieties within this species may cross with one another.
Can you plant two types of beans together?
Common beans, either pole or bush can usually be grown together with no crossing. It can happen, and it has happened in my garden, but normally does not. Just to be sure, you could put a little distance between your different varieties of beans so they are not in adjacent rows or trellises.
What will zucchini cross pollinate with?
Thus, zucchini squash will cross with crookneck or acorn squash, and cantaloupe can cross pollinate with honeydew melons, but melons don’t cross pollinate with cucumbers.
Which method of breeding is not appropriate for cross-pollinated crops?
(i) Standard selfing method:
Many lines are so poor in seed yield, pollen production, etc., that they cannot be used in a programme to produce single cross hybrid seed. (b) Effective selection within the row for the plants that have desired agronomic traits becomes minimal in generations beyond S3.
Can different vegetables cross pollinate?
First, cross pollination can only occur between varieties, not species. So, for example, a cucumber cannot cross pollinate with a squash. They are not the same species. This would be like a dog and a cat being able to create offspring together.
Can zucchini and pumpkins cross pollinate?
Zucchini, Yellow Crookneck, Acorn, Spaghetti, Patty Pan, Delicata, Pumpkins and Gourds (except edible snake gourds) all may cross with each other. Butternut, Buttercup, Banana, Hubbard and Turban squashes may cross with each other.
Do peppers cross pollinate?
Though peppers are capable of self-pollination, they often “cross-pollinate” and “outcross.” Cross-pollination occurs when pollen from a plant is transferred to the pistil of a flower of a different plant.
