Abstract
This paper aims to present the features of the new soybean cultivar UFUS Milionaria, which was developed by the Soybean Improvement Program of the Federal University of Uberlândia (UFU) through crossing between IAC-100 and Cristalina RCH cultivars, using the Single Seed Descent (SSD) method. UFUS Milionaria is resistant to many diseases caused by the fungus, bacteria, and virus. In addition, it also has been proved well-adapted to many Brazilian states, showing high yield even under water deficit conditions and Asian-rust infection; average yield was 4,451 kg ha -1 in 2015/16 growing season.
Highlights
Soybean [Glycine max (L.) Merr.] genetic improvement is a procedure regarding the development of variability for desired traits, identification of superior genotypes, and seeds multiplication intending commercial production
These include the pedigree method where best-appearance families, in each generation, are visually selected within each family one or more plants are chosen to advance to the generation; single-seed descent method which involves advancing one seed, or pod, from each plant to the generation in order to develop nearly homozygous lines; and bulk breeding method, which a population is advanced in bulk with no artificial selection until later generations, when nearly homozygous lines are selected for yield testing (Miladinović et al, 2011)
Soybean genetic improvement has been critical to the success of this crop in Brazil, and we have been contributing to this success by developing soy cultivars with genetic resistance to biotic and abiotic factors, which are promoting a profound impact on production and profitability
Summary
Soybean [Glycine max (L.) Merr.] genetic improvement is a procedure regarding the development of variability for desired traits, identification of superior genotypes, and seeds multiplication intending commercial production. The crossing of divergent parents produces the genetic variability of specific features intended to be transferred into new or improved varieties. The progenies from these crosses are allowed to natural genetic segregation through successive generations of self-fertilization, and new genotypes are formed. Soybean genetic improvement has been critical to the success of this crop in Brazil, and we have been contributing to this success by developing soy cultivars with genetic resistance to biotic and abiotic factors, which are promoting a profound impact on production and profitability
