Abstract
YH-1898 is a full season high yielding and high temperature tolerant maize hybrid, developed at Maize & Millets Research Institute, Yusafwala, Sahiwal. This hybrid is tolerant to high temperature and stalk rot (Fusarium moniliforme). It gives good yield in both Spring and Kharif seasons. It was developed by crossing two local inbred lines, Y22 ♀ and Y27 ♂ in 2005. The hybrid was evaluated under different agro-climatic zones of Pakistan during 2008-2014 in different yield trials. In Spring 2013, YH-1898 stood first (out of 34 entries) while in Kharif 2013 it was at 2nd position (out of 44 entries) with an average yield of 10243 Kg/ha and 9030 Kg/ha, respectively in National Uniform Hybrid Maize Yield Trial. YH-1898 attained maximum grain yield of 12,300 Kg/ha at Jhang in Kharif 2009 and 12,003 Kg/ha in Spring 2014 at Gojra in farmer’s field trails. In addition to being high temperature tolerant, it also stays green at maturity; hence its stalk can be used as fodder at harvesting. YH-1898 is the best hybrid recommended by the Punjab Seed Council during 2016 due to high grain yielding, high temperature tolerant, stay green at maturity and lodging resistance due to strong root anchoring. It has the potential to replace the Multinational hybrids presently under cultivation in Punjab.
