Abstract
AbstractAndrogenic dihaploids represent a unique form of dihaploids that have historically been utilized for cytoplasmic transfer, the generation of inbred lines and polyploid genome manipulations. Due to the apomictic nature of many Poa species, breeding improvements can be slow and difficult; therefore, alternative approaches that can capitalize on sampling the genetic diversity of near obligate Poa could be advantageous. This study investigates the frequency and potential use of androgenic derived dihaploids generated from a series of Poa arachnifera (Texas bluegrass) × Poa secunda (Sandberg bluegrass), Poa pratensis (Kentucky bluegrass) and Poa ligularis (Argentine bluegrass) interspecific hybrids. The examination of 2041 F1 hybrids generated from three interspecific hybridizations, confirmed the generation of 31 dihaploid individuals. Though low in occurrence, the generation of androgenic dihaploids derived through P. arachnifera interspecific hybridizations offers a non‐traditional breeding approach for sampling genetic variability of Poa species and the development of new breeding resources.
