METHODS The broccoli breeding program follows a one year breeding cycle. Cuttings from hybrids and inbreds are brought from the field in the fall and rooted in the greenhouse. Upon flowering during the winter, inbreds are bud pollinated to self-pollinate them and crossed with other inbreds to produce F1 hybrid seed.
How do you get seeds from broccoli?
The pods are what contain the seeds. Once the pods are dry on the broccoli plant, remove the plant from the ground and hang to dry for up to two weeks. Remove the dried pods from the broccoli plant and crush them in your hands or with a rolling pin to remove the seeds.

Broccoli seeds are best started indoors 7 to 9 weeks before the last frost, at a temperature of 70 to 75°F. They can also be sown outdoors 2 weeks before the last frost. For a winter crop in Zones 8 and warmer, sow in late summer. Expect germination in 10 to 14 days.
How many heads does broccoli produce?
So how much can you get out of a plant? Most varieties of Broccoli plant produce one primary head per plant that is typically around 8 ounces (225 g) in weight. However, an exception to this is, Sprouting Broccoli, does not produce a primary head instead it produces a number of small florets.

Standard hybrid broccolis such as Green Comet will generally take around 70 days from seed to produce a head in fall.
What insect pollinates broccoli?
In general, honey bees are the primary pollinators of broccoli seed crops but when the crop is allowed for wild pollinator’s quality and quantity of the seeds will increase (Bohart and Frank, 1961). However, growers are facing major problems in broccoli seed production due to inadequate pollination.
How do vegetables pollinate without bees?
You can likewise give the plants a little shake, or hand pollinate using a small paintbrush or cotton swab. In the greenhouse you can help these veggies simply by adding a fan to move the pollen. Corn—like other wind pollinated veggies, giving them a little shake helps distribute the pollen.
Can you pollinate a plant with itself?
Among other plants that can self-pollinate are many kinds of orchids, peas, sunflowers and tridax. Most of the self-pollinating plants have small, relatively inconspicuous flowers that shed pollen directly onto the stigma, sometimes even before the bud opens.
Will broccoli grow back after cutting?
Harvest the main broccoli head when it stops growing. You’ll know broccoli heads are ready when they’re deep green with small, tightly packed buds. Harvest broccoli right away if it starts to flower or turn yellow. Side shoots will continue growing after the main head is harvested.
