Maize has been a unique cereal credited with the highest genetic yield potential, adaptation to diverse growing environments, diverse utilization patterns and many genetics and genomics based breeding tools for making substantial improvement in both quantitative and qualitative traits. Inbred-hybrid tool however has been implied as a major breeding method to enhance production and productivity of maize. Development of heterotic hybrids adapted across the diverse growing environments of temperature, tropical and sub-tropical regions depends on the access and availability of inbred lines. Process of inbred development in maize using traditional breeding approaches is rather slow and time consuming. In vitro haploid-doubled haploid development is a way to accelerate inbred-hybrid development program in maize however, practically its application is limited due to anther/ovule based cumbersome process. Innovative in vivo haploid induction followed by haploid identification using R1-nj seed colour marker for the development of double haploid (DH) plants has enormous potential for genetic resource enrichment and ensuring availability of true homozygous inbred lines from diverse sources in a very less time span. Although, DH technology can potentially accelerate maize breeding, it still faces challenges at each step of DH line development. This article aims to highlights the mechanism of haploid induction, potential opportunities and key challenges in the integration of DH tool in maize improvement programme. [ABSTRACT FROM AUTHOR] |
