AJAYI, O. Lecture 10: hybrid seed production in paddy. Seed should be dried to 12% for short term storage and 8% for long term storage. igrowth sorghum contains a proprietary non-GMO imidazolinone tolerance technology, which allows farmers to spray the companion imidazolinone herbicide IMIFLEX from UPL for pre- or post-emergence control over broadleaf and grass weeds without causing damage to the crop. Josephson, M.T. At maturity the seeds of A-rows are harvested separately and care­fully as these hybrids and also the R-line seeds are harvested for next use. h�bbd``b`�$��V ��H�ۃ��@��*&F�@#i��G� �� 58 endstream endobj 778 0 obj <>/Metadata 32 0 R/Outlines 47 0 R/PageLayout/OneColumn/Pages 775 0 R/StructTreeRoot 58 0 R/Type/Catalog>> endobj 779 0 obj <>/Font<>>>/Rotate 0/StructParents 0/Type/Page>> endobj 780 0 obj <>stream Now customize the name of a clipboard to store your clips. Breeding sorghum - SlideShare 5.4. The shape of the seed is oval to round and the colour may be red, white, yellow, brown or shades thereof. %PDF-1.5 %���� Since both A-lines and B-lines exhibit synchronous flowering, seed yields on the A-line in A/B seed production plots are relatively better than in the A and R (hybrid) production plots.• Seed of the B-line harvested from the A/B production plots might be reused for the next generation, depending on the seed laws of the country. Alta Seeds also is working on the next generation of igrowth sorghum seed, including more geographic diversity for the grain sorghum lines and a series of sorghum silage options. For fertilizing the flowers of the female line, pollen has to come from the male plants. During hybrid seed production, the R line is cross pollinated with the A line to produce a hybrid seed.

Despite this potential, the sorghum and pearl millet hybrid industries have been limited by lack of a viable hybrid sorghum and pearl millet seed production systems.

DESSE SEED still holds true the values proven by previous generations of Dessert Seeds: reliability, quality and honesty. Looks like you’ve clipped this slide to already. Frequent visits to seed production plots are necessary to remove the off-type plants to maintain the quality and genetic purity of hybrid seeds. If you continue browsing the site, you agree to the use of cookies on this website. Improved methods of seed production are also provided. This information bulletin concentrates on certain aspects of varietal purity of sorghum and pearl millet when the variety/hybrid seed is being produced. A fundamental need for commercialization of sweet sorghum [Sorghum bicolor (L.) Moench] as a bioenergy crop is an adequate seed supply, which will require development of hybrid varieties using dwarf seed-parent lines. :�~�.��EN��U7��Tgg����Q\�=�2���)��2Tg��ۦ�������ɢ#C��y}�!w��ղ;=]�ys�|d��RJ6p���z��_]��f#�7���jQ/_��}�h*����?\�z�"�������zQ�y�Sv�JY]t����,�捐��f�QD�C�T8�n�պ�����8�P�S���r���˻�S�.

Owen, M.M. 7.1). male fertility or selfing in hybrid production fields, which can result in seed lots that do not meet seed law standards for a hybrid; costs associated with identification, development and registration of the compound. 5.6).Availability of fertility restorer sources in sorghum made it easy to develop hybrids and to commercially use the CMS source in producing fertile hybrid seeds. See our User Agreement and Privacy Policy. 777 0 obj <> endobj In sorghum, generally followed female to male ratio is 4:2. Hybrid seeds of crops with perfect flowers (a) Most crops species have perfect flowers, therefore, the availability of parental lines -male sterile, maintainers and fertility restorers - are absolutely necessary for hybrid seed production on a commercial scale.
