to evaluate the yield and yield components in additive intercropping system of grain sorghum (sorghum bicolor l.) and cowpea (vigna unguiculata l.) under limited irrigation condition, an experiment was conducted in research farm of college of agriculture, university of tehran, during spring 2006. the experimental treatments were arranged in split plots based on a complete randomized block desig...

Forage sorghum (Sorghum bicolor (L.) Moench) is a C4 cereal crop with excellent quality, which widely cultivated in many countries and regions. Acid detergent fiber found the stem leaf tissues of plant, main substance affecting digestibility livestock. It has very important impact on milk yield quality cows, dairy sheep pigs. In order to further understand its genetic mechanism, we re-sequenced...

The present investigation was undertaken to achieve information on gene action and combining ability in sorghum [Sorghum bicolor (L.) Moench]. experimental material consisted of eleven parents their 28 Line × Tester crosses. evaluation carried out during Kharif, 2020 at Sorghum Research Station, S. D. Agricultural University, Deesa. ratio σ2D/σ2H being more than unity found for days flowering, ...

Sorghum bicolor (L.) Moench lines with genetic differences in photoperiod requirement were planted in the field near Plainview, Texas (about 34 degrees northern latitude) around June 1 and treated with gibberellic acid (GA(3)) solutions applied in the apical leaf whorl. GA(3) hastened the date of floral differentiation (initiation). The greatest responses to GA(3) were by 90M and 100M, the late...

Cytogenetic maps of sorghum chromosomes 3-7, 9, and 10 were constructed on the basis of the fluorescence in situ hybridization (FISH) of approximately 18-30 BAC probes mapped across each of these chromosomes. Distal regions of euchromatin and pericentromeric regions of heterochromatin were delimited for all 10 sorghum chromosomes and their DNA content quantified. Euchromatic DNA spans approxima...

Sorghum genotypes currently used for grain production in the United States were developed from African landraces that were imported starting in the mid-to-late 19(th) century. Farmers and plant breeders selected genotypes for grain production with reduced plant height, early flowering, increased grain yield, adaptation to drought, and improved resistance to lodging, diseases and pests. DNA poly...
