1All are released varieties.
2R = Resistant; M = Mixture (Resistant and Susceptible type reaction may be segregating or seed mixture); MR = Moderately Resistant; MS = Moderately Susceptible; S = Susceptible; VS = Very Susceptible; I = Intermediate (variation in response has been observed); and T = Tolerant.
3The hydroponic technique used in this trial measures major gene resistance. Some of the varieties that are rated susceptible may have a high degree of field tolerance to Phytophthora root rot. Some of the varieties in this test are known not to have a major gene for Phytophthora resistance, but were rated resistant. This is believed to be an expression "field tolerance," (due to the use of a low inoculum potential).
4Ratings as made by plant pathologists at Mississippi State University.
5Nematode reactions as reported by R.D. Riggs, Plant Pathologist, University of Arkansas.
6"Score" gives an average rating of 40 plants stuck with a toothpick of stem canker inoculum. "Rating" is a scale or level of tolerance based on the score of the plants toothpicked: VS = 4.6-5.0; S = 2.0-4.5; MS = 1.5-1.9; MR = 1.2-1.4; and R = 1.0-1.1. Some lines or varieties exhibited a range of reactions to stem canker. These findings are expressed as ranges in the table (i.e. R-VS). In these ranges, letters in parentheses highlight a variety's predominant reaction. For example, "(R)-VS" means the variety ranged from resistant to very susceptible in its response; however, the predominant response was resistant. Varieties or lines that exhibitied such a range were mixes or were still segregating.
7Reaction to 0.125 hydroponic screening to metribuzin.

1R = Resistant; M = Mixture (Resistant and Susceptible type reaction may be segregating or seed mixture); MR = Moderately Resistant; MS = Moderately Susceptible; S = Susceptible; VS = Very Susceptible; I = Intermediate (variation in response has been observed); and T = Tolerant.
2The hydroponic technique used in this trial measures major gene resistance. Some of the varieties that are rated susceptible may have a high degree of field tolerance to Phytophthora root rot. Some of the varieties in this test are known not to have a major gene for Phytophthora resistance, but were rated resistant. This is believed to be an expression "field tolerance," (due to the use of a low inoculum potential).
3Ratings as made by plant pathologists at Mississippi State University.
4Nematode reactions as reported by R.D. Riggs, Plant Pathologist, University of Arkansas.
5"Score" gives an average rating of 40 plants stuck with a toothpick of stem canker inoculum. "Rating" is a scale or level of tolerance based on the score of the plants toothpicked: VS = 4.6-5.0; S = 2.0-4.5; MS = 1.5-1.9; MR = 1.2-1.4; and R = 1.0-1.1. Some lines or varieties exhibited a range of reactions to stem canker. These findings are expressed as ranges in the table (i.e. R-VS). In these ranges, letters in parentheses highlight a variety's predominant reaction. For example, "(R)-VS" means the variety ranged from resistant to very susceptible in its response; however, the predominant response was resistant. Varieties or lines that exhibitied such a range were mixes or were still segregating.
