Vivek QPM 9- An Early Maturing QPM Maize Hybrid

Maize (Zea mays L.) is one of the most important cereal crops in the world and contributes to food security in most of the developing countries. It is the third most important food crop in India after rice and wheat. In India, maize is cultivated in 9.2 mha with a production of 24.2 mt. The average productivity is 2632 kg/ha. It is cultivated throughout the year in all states of the country for various purposes including grain, fodder, green cobs, sweet corn, baby corn, and popcorn. Its importance lies in the fact that it is not only used for human food and animal feed but also widely used for corn starch industry, corn oil production etc. The increasing use of maize as feed, increasing interest of the consumers in nutritionally enriched products and rising demand for maize seed are the core driving forces behind emerging importance of maize crop in India. Protein malnutrition is a serious global issue draining huge resources on healthcare. The problem can be addressed to a considerable extent (especially among populations with maize as staple diet) by shifting to quality protein maize (QPM) diet. As the development of QPM hybrids through conventional breeding approach is a lengthy process, molecular-marker assisted approach was adopted for the expeditious development of high yielding maize hybrid Vivek QPM 9. It has wide adaptability and is released for cultivation in Jammu & Kashmir, Himachal Pradesh, Uttarakhand (Hill region), NE Hill Regions, Maharashtra, Karnataka, Andhra Pradesh & Tamil Nadu. Owing to its short duration, it can fit into various maize-based cropping systems prevalent in the country. • This variety has been developed from the cross VQL 1 x VQL 2. • Vivek QPM 9 is an early maturing (85-90 days) • High yielding (50-55 q/ha) hybrids. • Plant height is 160-170 cm. • Its grain is yellow in colour and semi-flint in texture. • Vivek QPM 9 showed 9-12% superiority in grain yield over Vivek Maize Hybrid 9. • VQPM 9 is the QPM Version of Vivek 9 and has Tryptophan 0.83% (compared to 0.59% in Vivek 9), Lysine 4.19 %, Fe 37 ppm and Zn 29 ppm. • It has long cylindrical cobs with good husk cover and medium bold grain (average 1000- grain weight is 325 g). • It is moderately tolerant to Turcicum and Maydis Leaf Blight. All these features make Vivek QPM 9 a hybrid of substantial commercial potential in food as well as poultry and cattle feed industry.
