In sorghum hybrid seed production, the female line used is male sterile. During hybrid seed production, the R line is cross pollinated with the A line to produce a hybrid seed. 0 %%EOF 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. Experimental Production of Hybrid Sorghum Seed with a Three‐way Cross 1. Josephson, M.T. procedures for hybrid seed production in both the crops are more or less the same. Seed should be dried to 12% for short term storage and 8% for long term storage. In sorghum, generally followed female to male ratio is 4:2. Seed treatment and storage The seeds are treated with captan or thiram @ 2 g/kg of seed and pack it in Hybrid seed is produced by crossing A × R lines in breeder seed production plot .

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. “A” line on pollination with the “R” line restores fertility of “A” lines and develops heterotic fertile F 1 seeds. 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 Breeding sorghum - SlideShare 5.4.

Merely said, the hybrid sorghum seed production breeding and research is universally compatible taking into account any devices to read. If only the flowering in the female line coincides with the flowering in the male line, proper pollination and seed set in the female are possible. A-lines crossed to 10 sweet sorghum restorer lines, overall heterosis was signifi cant for plant height, green cane yield, and commercial cane sugar yield (Meshram et al., 2005). Search for more papers by this author. To enhance productivity, several sorghum and pearl millet varieties have been developed and released, but adoption has been constrained by the inadequacies of the seed systems and crop management. 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. See our Privacy Policy and User Agreement for details. Processing . Lecture 08: hybrid seed production in maize. For F 1 hybrid seed production, A-line and R-line are grown together in 4: 2 ratio in hybrid production block (Fig. 1994.

Dr. Manyasa said the hybrid parents developed by ICRISAT will be used by seed manufacturers in Kenya and the East Africa region to produce a greater volume of hybrid seeds and sell them to farmers at affordable costs to boost production. Millets (sorghum, pearl millet and small millets) are the important food and fodder crops in semi- 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. 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. endstream endobj startxref •Forage sorghum seed is grown on 8000 acres (3200 ha) annually in Texas • Very little forage sorghum seed is certified • Sorghum/Sudan hybrid seed grown on 25,000 acres (10,000 ha) in Texas annually • 15%-20% of sorghum/Sudan hybrid seed is certified and is exported worldwide J.
