Soybean variety 90A07

#This invention is in the field of soybean breeding, specifically relating to a soybean variety designated 90A07.

#The present invention relates to a new and distinctive soybean variety, designated 90A07 which has been the result of years of careful breeding and selection as part of a soybean breeding program. There are numerous steps in the development of any novel, desirable plant germplasm. Plant breeding begins with the analysis and definition of problems and weaknesses of the current germplasm, the establishment of program goals, and the definition of specific breeding objectives. The next step is selection of germplasm that possess the traits to meet the program goals. The goal is to combine in a single variety an improved combination of desirable traits from the parental germplasm. These important traits may include higher seed yield, resistance to diseases and insects, tolerance to drought and heat, and better agronomic qualities.

#Field crops are bred through techniques that take advantage of the plant's method of pollination. A plant is self-pollinated if pollen from one flower is transferred to the same or another flower of the same plant. A plant is cross-pollinated if the pollen comes from a flower on a different plant. Soybean plants (Glycine max), are recognized to be naturally self-pollinated plants which, while capable of undergoing cross-pollination, rarely do so in nature. Insects are reported by some researchers to carry pollen from one soybean plant to another and it generally is estimated that less than one percent of soybean seed formed in an open planting can be traced to cross-pollination, i.e. less than one percent of soybean seed formed in an open planting is capable of producing F1 hybrid soybean plants, See Jaycox, “Ecological Relationships between Honey Bees and Soybeans,” appearing in the American Bee Journal Vol. 110(8): 306-307(August 1970). Thus intervention for control of pollination is critical to establishment of superior varieties.

#In the examples that follow, the traits and characteristics of soybean variety 90A07 are given. The data collected on soybean variety 90A07 is presented for the key characteristics and traits.

#The results in Table 2A compare variety 90A07 to another similarly adapted Pioneer soybean variety, 9004. The table shows that variety 90A07 is significantly higher yielding than variety 9004. Variety 90A07 also exhibits significantly superior plant lodging resistance and a significantly lower number of seeds per pound than variety 9004. Variety 90A07 is later to mature with a significantly higher absolute and predicted relative maturity score and demonstrates a significantly higher seed oil content than variety 9004.

#The results in Table 2B compare variety 90A07 to another similarly adapted Pioneer soybean variety, 9007. The results indicate that variety 90A97 is significantly higher yielding and exhibits a significantly higher seed protein content than variety 9007.
