ABSTRACT
A field trial was conducted for the comparative study of the 34 maize hybrids (CHT-I to CHT-34) along with two control lines i.e., Azam (Check-I) and Pioneer 30-K08 (Check-II). The seeds were sown in a randomized complete block design with two replications. Different agronomic features were observed including plant height, ear height, grain yield, days to 50% pollen shedding, days to 50% silking, and ear population per hectare. The analysis of variance revealed that the plant height, ear height, and grain yield indicated significant differences, while ear population per hectare, days to 50 % pollen shedding, and 50% silking showed non-significant differences. The least significant difference (LSD) means values revealed that maize hybrid CHT-3 produced the tallest plants (212.5 cm) and had a maximum ear height (111.7 cm) against other hybrids including both controls. The three maize hybrids ranked in the grain yield are CHT-17 (12.533 tonnes ha-1) followed by CHT-23 (11.861 tonnes ha-1) and CHT-6 (11.259 tonnes ha-1). The highest grain yield per hectare indicates their superior performance over all entries and both controls. The present study showed that maize hybrids that outperformed all other genotypes and controls in terms of plant height, ear height, and grain yield could be considered potential maize hybrids for approval after completing their adaptability studies and large-scale multi-location trials.
