BACKGROUND Pearl millet [Pennisetum glaucum (L.) R. Br.] is a staple food and fodder crop of marginal agricultural lands of sub-Saharan Africa and the Indian subcontinent. It is also a summer forage crop in the southern USA, Australia and Latin America, and is the preferred mulch in Brazilian no-till soybean production systems. Use of molecular marker(More)
Selection and use of genetically diverse genotypes are key factors in any crop breeding program to develop cultivars with a broad genetic base. Molecular markers play a major role in selecting diverse genotypes. In the present study, a reference set representing a wide range of sorghum genetic diversity was screened with 40 EST-SSR markers to validate both(More)
Use of diverse germplasm is a key factor which allows high level of resolution due to extensive recombination in the history. Therefore, population used in association mapping should posses as many phenotypes as possible. One of the methods to obtain most of the phenotypes is to construct the core collection. The ICRISAT foxtail millet core collection(More)
Pearl millet [Pennisetum glaucum (L.) R. Br.] is a widely cultivated drought- and high-temperature tolerant C4 cereal grown under dryland, rainfed and irrigated conditions in drought-prone regions of the tropics and sub-tropics of Africa, South Asia and the Americas. It is considered an orphan crop with relatively few genomic and genetic resources. This(More)
BACKGROUND With the advances in DNA sequencer-based technologies, it has become possible to automate several steps of the genotyping process leading to increased throughput. To efficiently handle the large amounts of genotypic data generated and help with quality control, there is a strong need for a software system that can help with the tracking of(More)
Low transpiration rates in pearl millet under fully irrigated conditions decrease plant water use at vegetative stage and then increase the water availability during grain filling and finally the terminal drought tolerance. Hundred and thirteen recombinant inbred lines developed from a cross between H77/833-2 and PRLT2/89-33 (terminal drought-sensitive ×(More)
Castor (Ricinus communis L.) is an industrially important oilseed crop and is the only source of an unusual fatty acid, ricinoleic acid in plant species. The castor oil and its products have numerous industrial uses including biofuel; hence, the demand for castor oil is ever increasing globally. Current productivity levels in castor are inadequate to meet(More)
Rust, caused by the fungus Puccinia substriata var. indica, is one of the most important production constraints of pearl millet worldwide, leading to grain yield losses of up to 76 % as well as major losses in fodder yield and quality. Here, we report the development of a linkage map integrating Diversity Arrays Technology (DArT) markers and simple sequence(More)
Castor (Ricinus communis L.) is an important oilseed crop providing raw materials for many industries. Its cultivation is seriously affected by the wilt disease caused by Fusarium oxysporum f. sp. ricini. In India, no cultivar could be released for cultivation without wilt resistance. Breeding for wilt resistance is hampered due to the limitation on number(More)
Drip irrigation studies were conducted in aerobic rice during the dry season (July–October) of 2011 in Coimbatore, Tamil Nadu, India with three levels of lateral distances (0.6, 0.8 or 1.0 m) and two discharge rates, viz., 0.6 and 1.0 litre per hour (LPH) emitters. Among the lateral distances, 0.8 m lateral distance adjudged as optimum spacing for better(More)
