Abstract

In this study, a set of nine parents, seventy-two F1’s (direct and reciprocals) and three standard checks was conducted in rabi, 2020 with three replications in randomized block design at research farm of All India Coordinated Research Project on maize Rahuri center Mahatma Phule Krishi Vidyapeeth, Rahuri Dist. Ahmednagar. The cross combinations, EC-639008 × IC-552819 exhibited high per se performance and highly significant standard heterosis for almost all the characters studied. The other combinations EC-639008 × IC-552819, EC-639232 × IC-552819, HYD-52327 × IC-552819 exhibited high per se performance with highly significant better parent and standard heterosis for kernel yield, yield contributing character with quality character in almost all the three environments. Among all the crosses, EC-639008 × IC-552819 was identified as superior, which ranked 1st for per se performance, with highest magnitude of standard heterosis for kernel yield per plant with other characters. These crosses should be evaluated in multilocation trials and could be used as hybrids.

Conclusion

In conclusion, among the tested cross combinations, EC-639008 X IC-552819 emerged as particularly notable, demonstrating high per se performance and significant standard heterosis across multiple characters studied. Additionally, combinations such as EC-639232 X IC-552819 and HYD-52327 X IC-552819 also exhibited commendable performance in terms of kernel yield, yield-contributing traits, and quality characteristics across different environments. Notably, EC-639008 X IC-552819 stood out as the superior hybrid, ranking first in per se performance and demonstrating the highest magnitude of standard heterosis for kernel yield per plant, among other traits. These findings suggest the potential of these identified crosses for further evaluation in multilocation trials, with implications for their use as high-performing hybrids in maize cultivation. Further research and field testing are warranted to validate and harness the full potential of these promising hybrids in enhancing maize productivity and quality.
