Asparagus propagation by division is one of the most common methods. When production of spears slows down over several years, it is time to cut the root into pieces. Dig up the root in late fall after the last ferns have died back. Cut it into several pieces, each with plenty of healthy root attached.
Asparagus seeds and crowns can be purchased at home and garden stores, nurseries or online. Seeds are available all year round, but crowns are usually for sale very early in the spring, right before they should be planted.

Further, asparagus fields need to be replanted every 8 to 10 years. The key factor causing seed shortage is insufficient production of clonal parent plants. Currently, asparagus parents are cloned by meristem culture, which is an effective but inefficient multiplication method.

Disease resistance in plants, as in animals, is nature's method of restricting parasites. Nature has been breeding disease-resistant plants since the world began.
Pair mating this is the method in which male and females are mated together rest of their breeding life. In this method in case of mice one male mated with one female and left together for the rest of their breeding life. In the case of rats, pregnant females should be isolated prior to delivery.
Organic asparagus production, like other vegetable production select varieties that have been bred hydro-cooling is the usual method used to pre-cool.

Census of agriculture estimates, kentucky asparagus harvested acreage falls between 35 and 65 acres, de-pending on the year. This indicates kentucky’s popu-lation is underserved for fresh asparagus. Asparagus use has increased nationally since the 1990s, with imports providing the increased quan-tity supplied.
Aflp markers are being used to develop linkage maps and a replicated planting of about 150 different clones will be used to measure spear quality, yield and other traits. The asparagus breeding project will be continued, but included in a new revision of project ca-r*-bps-4242h.
Plant breeding is defined as identifying and selecting desirable traits in plants and combining these into one individual plant. Since 1900, mendel's laws of genetics provided the scientific basis for plant breeding.
In the spring, dig a trench about 12 inches deep and 12 inches wide. Combine your compost, fertilizer, or other organic matter, and create mounds with it about 18 inches apart. Set the crown on top of the mound, spreading the roots down the sides.
•breeding programs have specific focus, such as climate and colour of asparagus •it is vital to select the right variety for your production location and market type •along with soil type and management, variety choice has the largest potential impact on the future profitability of your asparagus plantation.

To date, the main approach to managing asparagus beetle has been through the use of insecticide sprays.
Asparagus contains high concentrations of human health-beneficial compounds, notably rutin, protodioscin, and glutathione. To maximize positive effects, the potential for breeding high-phytochemical asparagus and the influence of different cooking methods on retention and antioxidant activity were assessed.
Progeny values before giving details of the different methods conducted in the almost one hundred years of documented breeding in asparagus, we will recall what is of primary importance when dealing with quantitative characters; that is, the differences between judging the merit of a genotype.
Used to develop alternative breeding methods depending on how it is transmitted to progeny. During the spring of 1996 we planted 1440 plants for future single-plant selections in the field. These consist of the following: 720 seedlings from seven open-pollinated california-european.

Following these methods should result in consistently more efficacious control efforts when using baits and burrow fumigants. For small infestations or where the use of a mechanical burrow builder is not feasible, use a probe to find the main tunnel next to a fresh mound or between two fresh mounds.
