Identification of haploids and diploids in maize using seedling traits and flow...
Baleroni,Alessandra Guedes; Ré,Fabrícia; Pelozo,Andressa; Kamphorst,Samuel Henrique; Carneiro,José Walter Pedroza; Rossi,Robson MarceloAbstract: The seedling traits is a simple and non-destructive methodology used to identify haploids/diploids in maize. This study aimed at establishing an optimal germination temperature to evaluate this methodology and verify its effectiveness. Haploid and diploid seeds, obtained from crosses with the haploidy inducer TAIL9, were classified using the R1-Navajo marker and placed to germinated in growth chambers...
Corn genotypes and crop seasons on the rate of putative haploids with the expre...
Silva,Hingrid Ariane da; Scapim,Carlos Alberto; Vivas,Marcelo; Amaral Júnior,Antonio Teixeira; Pinto,Ronald José Barth; Vivas,Janieli Maganha SilvaAbstract: The objective of this work was to evaluate the influences of the factors corn (Zea mays) genotypes, crop seasons, endosperm texture, genetic background, and genetic basis on putative haploid rates (PHRs) according to the expression of gene R1-navajo (R1-nj). Forty-one corn genotypes were evaluated as pollen receptors, in crosses with the Krasnodar haploid inducer, in two crops (summer and winter), in ...
