Abstract:

The new single cross maize hybrid YH-5427 is high yielding and high resistance against heat which developed at Maize & Millets Research Institute Yusafwala Sahiwal. The rise in temperature at pollination stage during May (40 C to 46 C) in spring planting maize is the main threat of yield loss, so there was need to develop such local hybrids which can tolerate against very high temperature without any yield loss. YH-5427 is also insect, lodging and stalk rot resistant. On station yield trial during Spring 2015 YH-5427 gave very high grain yield 13500 Kg/ha over check hybrid NK-8441 (10560 Kg/ha) in Preliminary Yield Trial. This hybrid was evaluated under different agro-climatic zones of Pakistan during 2017 to 2019 in National / Adaptability Uniform Maize Yield Trials. In Spring 2017, it stood first (out of 06 entries), in spring 2018 stood first (out of 55 entries) in Kharif 2018 stood first (out of 100 entries) and in spring 2019 stood first (out of 110 entries) with an average grain yields of (7141 Kg/ha, 9396 Kg/ha, 8669 and 8604 Kg/ha) respectively over local approved check hybrid YH-1898 with grain yields (5442 Kg/ha, 8555 Kg/ha, 6995 Kg/ha and 7172 kg/ha respectively). On Farm trials at different farmers' fields throughout various locations in Punjab, YH-5427 attained maximum grain yield of 12301 kg/ha at Mamu Kanjan in spring 2018 and 12003 Kg/ha at Arifwala in Spring 2019. This hybrid was also sown in last week of March and tested at very high temperature at pollination stage during Spring 2018 and YH-5427 gave very high yield over all local approved and multinational hybrids (13077 Kg/ha). This hybrid having high number of rows (16-20) per cob, long dented grain with thin pith and high shelling %age (90%). YH-5427 is equally good in Autumn season with an additional character of early maturing in Autumn (10 to 15 days early than multinational hybrids) with good yield that is best suitable for potato growing areas This new hybrid has approved by Punjab Seed Council in 52th meeting with the acknowledgement of its high resistance against heat and lodging for general cultivation in Punjab. It has the potential to replace high priced multinational commercial hybrids of spring season presently under cultivation in Punjab, Pakistan.
