Standard heterosis analysis in maize hybrids under water logging condition

Abstract

Maize is one of the important food and forage crops with abundant natural diversity. Determination of heterosis in CIMMYT maize hybrids under water logging condition is necessary for their commercial exploitation. The synthetics and composites have contributed to maize production in India in the initial stages of maize improvement programme, of late, hybrids are playing a vital role due to their high yielding potential. Breeding of water logging tolerant maize varieties will likely boosts maize production beyond the present level. Data derived from current study were complied to determine standard heterosis and identify high yielding hybrids. Among the tested 55 maize hybrids, the maize hybrids, namely, ZH17506, ZH17496 and VH11128 produced high heterosis which indicating that these hybrids are available for commercial cultivation. Maize hybrids that perform better than the checks could be used for release as hybrid variety after re-evaluation in multi-location trials. © 2020, Editorial board of Journal of Experimental Biology and Agricultural Sciences.
