NUNES and published by . This book was released on 1976 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic varation was investigated among 16 new restorer lines (R-lines) selected from the World Sorghum Collection, and one chemically induced mutant and its normal sib, used as male parents, and 14 newly developed cytoplasmic male sterile lines (A-lines) and four standard commercial A-lines, used as female parents. The 18 R-lines were divide in two groups. The 16 lines from the World Sorghum Colletion were first randomly subdivided into two groups of eight. The two ramaining R-lines were added to each of the two groups of eight so that each of the two groups of males was composed of 10 lines. The eight new R-lines were referred to as random males because they were regarded as a random sample from a much larger number of phenotypically desirable R-lines that could be identified in the World Sorghum Collection. The induced mutant and its normal sib were called fixed males. Similarly, the 14 new A-lines were divided at random into two groups of seven. The four standard male sterile lines were added to each of the groups so that both groups of females had 11 lines. The 14 newly developed A-lines were called random females because they were regarded as a random sample from a much larger number of phenotypically desirable A-lines that could be developed from the World Sorghum Colletions. The four standard A-lines were called fixed females because they were deliberately closen. Each of the two groups of males was matched at random with one of the two groups of famales. As a result, two "AB" overall mating (...).

Available in PDF, EPUB and Kindle. Book excerpt: Genetic Enhancement of Rabi Sorghum – Adapting the Indian Durras presents both the historical background and the recent research done in breeding this important world crop for more global production. Its chapters cover topics in origin and taxonomy, morphology and breeding behavior, genetics, and cytogenetics, also looking at production, nutrition, and alternate uses. The durra race is Ethiopian in origin and its introgression with wild forms permitted adaptation to drier conditions. These have migrated and adapted to the currently known crop that is cultivated in the winter season and commonly called rabi sorghums. Grown under receding soil moisture conditions, rabi sorghums have tolerance to abiotic stresses apart from biotic stresses, unlike the rainy sorghums that are grown widely in the world. However, they must be more resilient to rapid changes in climate, for example. The variability from winter sorghums is being introgressed into rainy sorghums. With the yield plateaus reached and sorghum gaining importance as a food crop, this book will be of importance to those studying durras and their breeding. Presents both the historical background and most recent research done in breeding rabi sorghum for more global production Provides information on the adaptation of the crop and the ways it has migrated to the currently known crop, which is cultivated in winter season and commonly called as rabi sorghum Explores strategies for resilience as the crop must be prepared to withstand rapid and varying changes in climate

This book was released on 2006 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of AFLP markers allowed the identification of five strong clusters through estimates of genetic similarities. This classification did not group the lines by either their genetic background or their fertility reaction. This study provides information to identify specific combinations that would help to understand heterotic relationships in sorghum, and support the suggestions made by Menz and Gabriel that races in sorghum are not well defined.

This book was released on 2014-01 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Post rainy sorghum is unique to India, which is mostly grown on residual soil moisture in southern states, subjected to various biotic and abiotic stresses. Keeping in view the low heterosis in post rainy hybrids compared to rainy season hybrids, the study was taken up with 41 genotypes to enumerate the approaches for enhancing the level of heterosis. There was a positive relationship between heterosis for grain yield and major yield components. Genetic diversity analysis showed importance of inter as well as intra group divergence in expression of heterosis. There was a general positive trend between hybrid yield and sca effect but at least one general combiner was involved in highest yielding crosses and there was positive relationship between heterosis and mean gca of parents. Major yield components were controlled by non additive gene effects hence it is proposed to breed parental lines with high gca effect with capability to produce high sca effect in hybrid combination to enhance the level of heterosis and productivity. The information in this book is useful for sorghum breeders and geneticists for formulating effective crop improvement programme.

This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several studies have shown that disease resistance genes diverge under recurrent positive selection as a result of a molecular arms-race between hosts and pathogens. However, these studies have been conducted mainly in animals and few plant genes have been shown to evolve adaptively. The study of plant molecular adaptation for disease resistance is fundamental to our understanding of plant-microbe interactions and to the development of novel plant breeding strategies. Here, we combined information from the expression pattern of Sorghum bicolor genes and their divergence to rice in order to identify candidate disease response genes (DRGs). We used evolutionary analyses of orthologous DRG sets from grass species to identify positively selected genes and the targeted residues. Six genes showed a pattern of substitution consistent with positive selection: a thaumatin, a peroxidase and a barley mlo homolog, all known antifungal proteins; and a MADS box gene, an eIF5 gene and a gene of unknown function: SESPY. All adaptive sites mapped to the surface of the crystal structures of peroxidase and thaumatin and several are close to the active sites. This information provides a basis for functional validation studies, the identification of accessions having variation at important residues and the rational design of DRGs. Rapid divergence through positive selection should correlate to reduced intraspecific polymorphism. Here we compare the macroevolution and intraspecific polymorphism of positively selected disease response genes and show that the patterns of polymorphism found are consistent with both selective sweeps and balancing selection. The sorghum mlo homolog and SESPY, have old, divergent alleles, while a peroxidase and a gene with a RNA binding domain have significantly reduced diversity suggesting a recent selective sweep. Finally, we show that sorghum DRGs are significantly closer to the telomere and have more exons than a control set of evenly expressed genes. The evidence from gene location; structure; macro-evolution and polymorphism of these DRGs point to the great selective pressure produced by pathogens which has driven the evolution of cereal genome content, order and function.
