- ... Efficient production and use of doubled haploid lines can greatly accelerate genetic gains in maize breeding programs. One of the critical steps in standard doubled haploid line production is doubling the haploid genome using toxic and costly mitosis-inhibiting chemicals to achieve fertility in haploids. Alternatively, fertility may be spontaneously restored by natural chromosomal doubling, althou ...

- ... Every cultivar released in Nebraska must have four characteristics: improved agronomic performance relative to existing cultivars, exceptional winterhardiness, resistance to Puccinia graminis (the causal agent of stem rust), and acceptable end-use quality. This paper will discuss our strategy for breeding cultivars with acceptable end-use quality. All experimental lines are derived from crosses wi ...
