However, this technology has still unlimited challenges that will have to be addressed in the future. The extent and magnitude of different challenges vary considering hybrid types that are emphasized. From the past experience, it appears that the development of good progenitors continues to be a crucial and most difficult challenge to meet. The paper will also touch on various fragile areas in hybrid maize research including combining ability, inbred hybrid correlations, exploring options in inbred line development and a whole range of other issues where the theoretical and practical considerations dictate different strategies. Improving economics of hybrid maize seed production is equally important and is a never ending challenge as there is always a room for further improvement. In fact, inbred performance is a decisive factor in choosing hybrid option. The need for strengthening inbred base maize germplasm will be discussed and some of the biodiversity concerns will be raised and some solutions proposed. We must also show readiness to meet new emerging problems and in that context we should make every effort to stay ahead by continuous and conscious monitoring of such problems. Opportunities for accelerating hybrid development efforts in the future will be discussed. Some suggestions in this regard will be made that will result in multiplier effect of each others effort. Achieving stability of production is an important goal and this can be met by excercising selection for biotic and abiotic stresses. In the end, the paper will discuss exciting opportunities using new bioscience technologies as tools in maize improvement and hybrid development efforts.Collection: CIMMYT Staff Publications Collection
