This QPM hybrid seed collected from Kholapur, Maharastra, India was found contaminated with selfed seed (12.5%) which may have arisen either through self pollination of female parent or mechanical mixtures. Hybrid maize is produced by crossing two pure lines with high combining ability About Corn (Maize) Native American corn was the genetic foundation of all other corn varieties. Indian corn is rarely grown in the garden today. Columbus was one of the first Europeans to see maize or corn. The Pueblo Indians were raising irrigated corn in the American Southwest when Coronado visited in 1540
The total cultivated area of maize in India is over 9.0 million ha (2013-14), with most of the Indian states growing it. Ten states in India represent around 80% of the total area of maize grown n eastern and southern Africa (ESA), maize is the most important crop, accounting for up to 40 to 50% of both calories and protein consumed in Malawi, Zimbabwe, and Zambia, the most maize-dependent countries in the region (FAOSTAT, 2010). However, maize yields in this region remain low averaging 1.4 The current Seeds Act, as already noted, applies only to notified varieties. Also, unless a variety or hybrid is notified, its seeds cannot be certified. Most of the private hybrids marketed in India, by virtue of not being officially released, are neither notified nor certified. Instead, they are truthful labeled While numerous sorghum hybrids have been released in Africa, average yields have generally remained stagnant, largely because the hybrid variety being planted is not optimal for the geographic region (Pixley, 2006) and yield stagnation in Kenyan maize hybrids has shown a similar trend. National programs and most seed companies in Africa have. This hybrid variety of maize, which is ideal for use in products made of baby corn, has been approved for commercial cultivation. Department of Genetics and Plant Breeding Senior Scientist Harishchandra has developed this new maize variety, Hybrid Azad Maize 1, which will produce 55-60 quintals per hectare and will be ready for harvest in 85.
3. Hybrid Millets: The development of hybrid varieties of maize, Jawar and bajara, deserves a special mention. A programme to develop hybrid maize began in India over four decades ago in collaboration with Rockefeller and Ford Foundations. Several hybrid varieties have been released since then Seeds should be sown about 2.5 cm (1 in) deep and 10-15 cm (~3-4 in) apart allowing 76-91 cm (~30-36 in) between rows. Maize should be planted in blocks (numerous rows) rather than in a single long row as it is wind pollinated and pollen can transfer between plants much more efficiently Precise information on the content and composition of nutritionally essential metabolites in food crops is a prerequisite for dietary recommendations and nutrient-dense food formulations. In the present study, the fatty acid profile of 21 Korean maize hybrids was analyzed by gas chromatography (GC)-mass spectrometry (MS). In the studied hybrids, linoleic acid (LA; C18:2n6c) was dominant (38. Vivek Maize Hybrid 9- a popular single-cross hybrid developed by crossing CM 212 and CM 145 was released for commercial cultivation in India.
