Available in PDF, EPUB and Kindle. Book excerpt: Cold temperature stress is an important abiotic constraint to grain sorghum production in temperate regions. In the United States, low temperature in late spring and early fall has limited sorghum production to a narrow growing period. Deployment of cold tolerance traits may widen this window and hence contribute to increased production. The objectives of this study were (1) to determine the effect of early and mid-season cold temperature stress on growth, phenology and yield components of sorghum, and identify key traits that are most sensitive to cold stress at seedling and flowering stages, and (2) to identify new sources of cold tolerance for use in breeding programs. Series of controlled environment (greenhouse/growth chamber) and field experiments were carried out. Three sorghum genotypes of variable response, Shan Qui Red (tolerant), SRN39 (susceptible) and Pioneer 84G62 (unknown) were subjected to cold (15/13°C day/night) and normal (25/23°C day/night) temperature at seedling (Experiment I) and flowering (Experiment II) stages. The genotypes were planted in a greenhouse using a 5L polytainer pots. Each pot consisted of a single plant and each plot was represented by three pots. A split-plot design with three replications was used in both experiments with temperature regimes as main plots and genotypes as sub-plots. Three days after emergence, experiment I plants were moved to the growth chamber and subjected to the designated temperature treatments. For experiment II, the treatments were assigned at heading stage immediately before anthesis had begun. The treatments lasted 10 d in both experiments. Data were collected on seedling characteristics and leaf chlorophyll content in experiment I, days to flowering, maturity, and yield components in both experiments, and anthesis duration in experiment II. For the field experiment, 150 sorghum germplasm collections of potential cold tolerance along with tolerant and susceptible checks were evaluated for emergence and seedling traits under early planting (April 13) at soil temperature of 20.1/13.4 °C max/min. The normal temperature treatment was applied by planting at regular season (May 26) at soil temperature of 30.0/20.4°C max/min. Twenty-four genotypes selected based on field emergence and seedling vigor were further screened under controlled environment. Early-season stress significantly reduced leaf chlorophyll content, all seedling traits (height, vigor and dry weight), and also delayed flowering and maturity. But it had no effect on final leaf number, plant height and yield components. Genotypic response to early stress was significant for all traits with the susceptible checks having the lowest score for all seedling traits. Mid-season cold stress prolonged anthesis duration, delayed maturity and highly reduced all yield components. Several genotypes among the 150 had higher seedling vigor and emergence than the tolerant check, Shan Qui Red. In conclusion, reduced seedling vigor as a result of early stress had no effect on final yield provided that stand establishment was not compromised while mid season stress is damaging to yield. The wide genetic variation for the traits indicates the potential for improvement of cold tolerance in sorghum.

This book was released on 1982 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Seed of 36 sorghum (Sorghum bicolor (L.) Moench) geneotypes selected on the basis of high physiological quality were evaluated to determine genotypic differences in response to germination temperatures ranging from 10 to 42C. Seed of high, medium, and low quality were evaluated to investigate seed quality-germination-tempearture relationships. Seed of 24 genotypes were dimensionally sized and permitted to imbile water to evaluate both genotypic variation in speed of water uptake and the influence of seed size on water imbibition. Sorghum seed of near maximum phusiological quality germinated equally well at temperatures between 20 and 30C. Among the range of genotypes evaluated, constant germination temperatures of 14 and 42C were the best for screening genotypes for their to germinate at low and high temperatures, respectively. Two genotypes, IS 1166C and SC 175-14, were equal to or better than all other genotypes at all germination temperatures evaluated. Five genotypes, E 35-1, MN 1958, MN 4508, IS 12685C and TPDXB1388 (9256) were very sensitive to germination temperatures outside the optimal range. Seed of lower physilogical quality were more sensitive to germination temperatures than those of high quality. However, there was a differential response among the genotypes. Regardless of genotype, small seed increased in moisture content more rapidly than large seed when water supply was not limited. Within the same size. there was genotypic varation both in the rate of moisture absorption and the time (...).

This book was released on 2021-01-04 with total page 932 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sorghum is the most important cereal crop grown in the semi-arid tropics (SAT) of Africa, Asia, Australia and Americas for food, feed, fodder and fuel. It is the fifth most important cereal crop globally after rice, wheat, maize and barley, and plays a major role in global food security. Sorghum is consumed in different forms for various end-uses. Its grain is mostly used directly for food purposes. After the release of the proceedings of two international symposia in the form of books “Sorghum in Seventies” and “Sorghum in Eighties”, global sorghum research and development have not been documented at one place. Of course, few books on sorghum have been released that focus on specific issues/research areas, but comprehensive review of all aspects of recent development in different areas of sorghum science has not been compiled in the form a single book. This book is intended to fill in a void to bridge the gap by documenting all aspects of recent research and development in sorghum encompassing all the progress made, milestones achieved across globe in genetic diversity assessment, crop improvement and production, strategies for high yield, biotic and abiotic stress resistance, grain and stover quality aspects, storage, nutrition, health and industrial applications, biotechnological applications to increase production, including regional and global policy perspectives and developmental needs. This book will be an institutional effort to compile all the latest information generated in research and development in sorghum across the globe at one place.

Available in PDF, EPUB and Kindle. Book excerpt: Breeding Sorghum for Diverse End Uses is a comprehensive overview of all significant global efforts for the genetic improvement of sorghum, a major crop of many semi-arid nations that is suitable for a huge range of uses, from human food, to biofuels. Split into two main sections, the book initially reviews the genetic suitability of sorghum for breeding, also providing the history of the genetic improvement of the grain. Finally, other sections look at specific breeding programs that could be improved in a number of areas, including human food, animal feed and industrial usage. Readers in academics, research, plant genetics and sorghum development will find this resource of great value. In addition, it is essential reading for engineers who utilize sorghum for food, feed and industrial materials in industry. Provides information on key advances in the genetic makeup of sorghum Allows plant breeders to apply this research to effectively breed new strains of sorghum that are dependent on final usage goals Includes the latest findings in each section to orient researchers to plans for future genetic enhancement
