Inheritance patterns of the response to in vitro doubled haploid induction in perennial ryegrass (Lolium perenne L.)

Popis výsledku v původním jazyce

The ability to produce doubled haploid (DH) plants has found broad application in research and breeding. For major crop species such as maize (Zea mays L.) and barley (Hordeum vulgare L.), routine large-scale p roduction of DHs has enabled the acceleration of breeding processes, for example through efficient generation of homozygous lines. However, in forage crops such as perennial ryegrass (Lolium perenne L.), low and genotype-specific responses to in vitro anther culture (AC) still limit wide-spread use of DHs. Here, we report the responses of nine bi-parental populations, segregating for microspore embryogenesis and plant regeneration capacity, to an effective AC protocol. Genotypes of exceptionally high androgenic ability, producing over 200 green plants per 100 anthers cultured, could be selected. Continuous and distinctly shaped distributions for the evaluated traits were indicative of quantitative polygenic control and the presence of different alleles in each population. An insignificant association of embryo production with plant regeneration, as well as a low correlation between green and albino plant yield (ρ = 0.20), suggested that different genes influence these traits. The populations evaluated here provide a rich source of alleles needed for the introgression of high levels of androgenic capacity into recalcitrant material. Moreover, this germplasm is ideally suited for use in future genotyping and mapping studies so that the genetic control of androgenic capacity in perennial ryegrass can be elucidated. Ultimately, our results will help to realize the potential of DH induction in one of the world’s most important forage crop species.
