Not AvailableThe productivity of millets particularly sorghum, pearl millet and finger millets are affected by occurrence of many diseases, of which grain mold, downy mildew, blast and ergot are economically very important. Grain and forage yield and quality get compromised because of infection of these diseases. The diseases are mostly managed through cultural manipulations along with host plant resistance and occasionally by application of fungicides or bio-control agents. Continuous efforts for identification of resistance sources and their incorporation in different millets for development of disease resistant cultivars and hybrid parental lines are necessary to cope with these diseases. This hand book provides pictorial descriptions of all the major diseases of millets and summaries their control measures.Not Availabl

Not AvailableThe farmers’ socio-economic condition is complex and resource-poor where several factors were at interplay. The role of the farmers in the whole system is more on the receiving end as ‘passive subjects’ rather than ‘active stake holders’ despite the fact that sorghum and other millets constitutes one of their main sources of livelihood. In order to achieve the goal of doubling farmers’ income through millets cultivation, there is need of viable strategy comprising of three major elements: (i) scientific crop cultivation in participatory mode and capacity building with support of R&D organizations coupled with inputs supply in single window mode, (ii) promotion of value-addition and creating market demands through collective action like, formation of FPOs and SHGs, and (iii) policy support for buy back arrangements with MSP, crop insurance, inclusion in MDM and PDS system, infrastructure for farm-gate processing and warehouses.ICRISA

A new epicuticular wax (bloom) locus has been identified and fine mapped to the 207.89 kb genomic region on chromosome 1. A putative candidate gene, Sobic.001G269200, annotated as GDSL-like lipase/acylhydrolase, is proposed as the most probable candidate gene involved in bloom synthesis/deposition.
Abstract
Deposition of epicuticular wax on plant aerial surface is one strategy that plants adapt to reduce non-transpiration water loss. Epicuticular wax (bloom)-less mutants in sorghum with their glossy phenotypes exhibit changes in the accumulation of epicuticular wax on leaf and culm surfaces. We report molecular mapping of a new sorghum locus, bloomless mutant (bm39), involved in epicuticular wax biosynthesis in sorghum. Inheritance studies involving a profusely bloom parent (BTx623) and a spontaneous bloomless mutant (RS647) indicated that the parents differed in a single gene for bloom synthesis. Bloomless was recessive to bloom deposition. Genetic mapping involving F2 and F7 mapping populations in diverse genetic backgrounds (BTx623 × RS647; 296A × RS647 and 27A × RS647) identified and validated the map location of bm39 to a region of 207.89 kb on chromosome 1. SSR markers, Sblm13 and Sblm16, flanked the bm39 locus to a map interval of 0.3 cM on either side. Nine candidate genes were identified, of which Sobic.001G269200 annotated for GDSL-like lipase/acylhydrolase is the most likely gene associated with epicuticular wax deposition. Gene expression analysis in parents, isogenic lines and sets of near isogenic lines also confirmed the reduced expression of the putative candidate gene. The study opens possibilities for a detailed molecular analysis of the gene, its role in epicuticular wax synthesis and deposition, and may help to understand its function in moisture stress tolerance and insect and pathogen resistance in sorghum.Not Availabl

Not AvailableIn this present era, consumers prefer high-quality foods with longer shelf life. They also look for products which are convenient to prepare as people are too busy in their daily schedule. Moreover, people have increased their tendency to eat a greater variety of foods both traditional and conventional. Efforts are being made to create awareness on the potential health benefits of millets which are recommended for obese, diabetic, celiac and other lifestyle diseases. In order to make millet value chain sustainable, the production and promotion of
various products in the market is very much essential. Under this motto, IIMR launched its brand name “Eatrite
” to the Indian markets to promote the millet based products and this book gives details of these products.ICAR-Indian Institute of Millets Reserac

Not AvailableIn order to know the variation in seed quality among the varieties and hybrids (public, private sector) of sorghum collected from different market outlets. A total of 52 lots (38 cultivars) were evaluated for seed germination and seedling vigour. The values ranged significantly from 1.67 g (KDSH 302) to 4.60 g (MRS a6 9) for hundred seed weight;55% (CSH 16) to 97% (CSH 14) for seed germination; 9.2 cm (CSH 1.6) to 16.93cm (JKSH 434) for root length; 11.15 cm (MSH 51) to 20.95cm (Sudhama 333) for shoot length; 10.21 mg (KDSH 302) to 28.22mg (MRS 4649) for seedling dry weight and 728 (KDSH 302) to 2196 (JKSH 22) for seedling vigour index traits. Whereas, CSH 16, JKSH 474, NSH 36, KDSH 302, CSH 9, NSH 18, MDSH 262 ,VIH 540, MSH 51 and'Local farm market (Udaipur)' showed low values of germination ranging from 55 to75% (lesser than minimum seed certification standard) which is alarming and needs attention for searching the causes and solutions. The differences for these seed quality traits within the cultivar were also observed due to different market sources as found in 11 cultivars. Farmers become aware of vigour differences when the germination test fails as measure of quality for expensive seeds. The study highlights the importance of seed vigour and suggests the supply of standard quality seed by seed industry which is essential to realize the performance of cultivars on farmer field.
