New inducers of maternal haploids in maize
WebGenomics is enabling a renaissance in all disciplines of plant biology. However, many plant genomes are complex and remain recalcitrant to current genomic technologies. The complexities of these nonmodel plant genomes are attributable to gene and genome duplication, heterozygosity, ploidy, and/or repetitive sequences. Methods are available to … WebMethods for producing a maize plant comprise crossing maize variety 1PQQS32 with another maize plant are provided. Methods for producing a maize plant containing in its genetic material one or more traits introgressed into 1PQQS32 through backcross conversion and/or transformation, and to the maize seed, plant and plant part produced …
