  Maize, the leading world cereal, offers the greatest potential for increasing food productivity in countries like Pakistan. The average yield in Pakistan is low compared to the world average. An effective short term strategy to improve maize productivity is to replace the local low yielding varieties and landraces with high yielding hybrids. However, mainly due to very high cost of the imported hybrid seed in Pakistan, the hybrid technology has not been adopted on larger scales. Currently, 25% of the maize area is under hybrids in Pakistan. Therefore, there is a great need to develop, popularize and adopt maize hybrids with indigenous blood. Indigenous hybrids for agro-ecological zones not attended by the private multinational have been developed at National Agricultural Research Centre and tested in the respective ecologies. Six selected indigenous hybrids (NARC-2701, NARC-2702, NARC-2703, NARC-2704, NARC-2705, NARC-2707) were evaluated at two location during spring season. Four leading commercial hybrids (Bemisal-202, 3335, 2303 and 6525 from Engro, Pioneer, Rafhan and Monsanto) were used as checks for comparison. Some of the indigenously developed hybrids (NARC-2702, NARC-2703, NARC-2704, NARC- 2705) performed better than, or as good as their exotic counterparts. These hybrids exhibited desired idiotypes as indicated by plant and ear heights. The indigenous hybrids were earlier in maturity than the commercial checks. These results clearly indicate the superiority and suitability of locally developed (indigenous) maize hybrids for spring planting in Pakistan.

  Six maize genotypes were evaluated in National Uniform Maize Yield Trials across six contrasting locations having different agro-climatic conditions. Pooled analysis of variance for grain yield indicated significant differences for genotypes across the environments, environment across genotypes and their interactions. These significant interactions indicated uneven performance of the genotypes across the environments and years. In stability analysis, all the parameters applied proved two genotypes as the most stable across the environments. These genotypes gave the highest grain yield and were also earlier in maturity. One genotype showed fitness for favourable environments and two for poor yielding environments.
