After a new variety was produced by crossing two varieties, a farmer propagated this new variety by saving the seed from the most desirable ears from the most desirable plants each fall. These ears were open-pollinated ears. That is, there was no effort to control the source of the pollen.

Open-pollinated plants are usually more genetically diverse. This causes an amazing variation within plant populations, which ultimately allows them to adapt to local growing conditions and climates every year. Think of corns that has multiple colors of corn kernel per cob.

The tables on the following two pages show the yield data for each of the open-pollinated corn varieties we evaluated together with the commercial hybrid varieties for comparison. Each table is in order of grain moisture, from the driest to the wettest.

Open-pollinated varieties and synthetics are types of corn populations. Until the introduction of double- and then single-cross hybrids, farmers grew open-pollinated varieties. Unlike hybrids, seed production of these varieties requires no controlled pollinations.

lizer was tested to evaluate the effects and performance on the growth and yield of open-pollinated variety (OPV) young corn. The result of the study showed that OPV corn fertilized with...

2010年1月15日 · Time Isolation - 18 to 20 days gap of flowering before and after planting of any corn. Distance Isolation - Minimum of 300m without barrier. In the presence of natural barriers such as sugarcane, banana, and other plantation crops taller …

2023年8月11日 · Open pollinated (OP) seeds are seeds that are produced from cross-pollinating two of the same variety of plant, usually by wind, birds or insects, resulting in plants that are very similar, but naturally varied. Open pollinated seed saving is the oldest of the three methods of producing seed.

2024年6月26日 · Open-pollinated corn pollinates naturally without human intervention, resulting in genetically diverse plants. Farmers historically improved open-pollinated corn by saving seeds from the best ears each year. Saving seeds from open-pollinated corn allows adaptation to local growing conditions.

OP corn will usually thrive well under organic conditions. OP corn usually stands well while it is green, but as it dries, the standability declines especially at higher populations. The biggest difference of OP corn is that seed can be saved and re-used the next year.

Both white OPV varieties are exceptional in terms of production and offer favorable agronomic traits such as early maturity, good ear length, and good shelling recovery. The registered white OPV corn varieties ensure a thriving corn seed industry by …
