Book Description
This work is based on the Mexico 2000 meeting under the auspices of ICRISAT (International Crops Research Institute for Semi-Arid Tropics) and INTSORMIL (International Sorghum and Millet Collaborative Research Support Program). Sorghum and millet are very important agronomic crops in many parts of the world, specifically in the semi-arid regions in warm areas. The crops are of great significance in supplying food and feed in the developing areas of Latin America, Africa, and Asia.

Book Description
Sixteen Peronosclerospora sorghi populations from seven countries were evaluated for variability is their virulence pattern on sorghum. All population were identified as distinct vertical pathotypes based on differential sporulation on defined sorghum differentials. Cultivar-by=isolate interactions were consistent with Flor"s gene-for-gene hypothesis. Sorghum cultivars IS1032, IS2473, IS3546, IS14332, IS14387, IS22227, IS22228, IS22229, IS22230, and QL-3, India were resistant to all isolates of P. sorghi tested. These cultivars are considered to be stable and durable sources of sorghum downy mildew (SDM) resistance. Most of the SDM-resistant converted cultivars from Texas remained resistant to isolates from the Americas, whereas they were susceptible to the isolates from India and Africa. P. sorghi isolates from India and Africa had a wider range of virulence compared to the isolates from the Americas. The correlation coefficient between degree of conidial sporulation on inoculated sorghum cultivars and percent SDM incidence was 0,9348. To determine the diversity in sources of resistance, sorghum cultivars that posses resistance to Texas pathotypes 1 and 3 were inoculated with conidia at seed germination, . On the basis of percent SDM incidence, cultivars were grouped into resistant, heterogeneous and susceptible classes. Sexuality is P. sorghi was evaluated by attempting to isolate mating types and by establishing the relationship between origins of gametangia. Attempts to isolate mating types failed., Light microscopy and scanning electron microscopy revealed that male and female gametangia are borne on the same vegetative hypha, i.e., that P. sorghi is homothallic. One isolates of P. sorghi (Thailand) was compared with five isolates of P. sorghi for mean number of nuclei per conidium. The mean number of nuclei (10.07) of purported P. sorghi (Thailand) differed significantly from mean number of nuclei (14.26) of the species P. sorghi. The mean of purported P. sorghi (Thailand) was significantly different from each of the other P. sorghi isolates. There isolates each of P. sacchari and of P. philippinensis were compared for mean number of nuclei. Significant differences among isolates were evident within both species, but mean number of nucleic of species P. sacchari was not significantly different from the mean of species P. philippinensis.

Book Description
Millets and sorghum are extremely important crops in many developing nations and because of the ability of many of them to thrive in low-moisture situations they represent some exciting opportunities for further development to address the continuing and increasing impact of global temperature increase on the sustainability of the world’s food crops. The main focus of this thorough new book is the potential for crop improvement through new and traditional methods, with the book’s main chapters covering the following crops: sorghum, pearl millet, finger millet, foxtail milet, proso millet, little millet, barnyard millet, kodo millet, tef and fonio. Further chapters cover pests and diseases, nutritional and industrial importance, novel tools for improvement, and seed systems in millets. Millets and Sorghum provides full and comprehensive coverage of these crucially important crops, their biology, world status and potential for improvement, and is an essential purchase for crop and plant scientists, and food scientists and technologists throughout the developed and developing world. All libraries in universities and research establishment where biological and agricultural sciences are studied and taught should have copies of this important book on their shelves.
