(Results of more than 500 will not return images.)
This search will show only accessions that have material that may be requested, including those not seasonally available.
You may list accessions with separators (commas or semicolons, as shown below) or by entering them on separate lines, such as
PI 651794

| 0 | PI 665408 | 'F1025' | Beta vulgaris L. subsp. vulgaris | North Dakota, United States | W6 | | | 2012 | DEVELOPED | PRE 2012 | | | | | Breeding material | F1025 was selected almost exclusively for low sodium concentration in the mature root. Sodium interferes with sucrose extraction in normal factory operations. The sodium concentration of F1025 was 57% of the sodium concentration of the parental population. F1025 had a slightly higher sucrose concentration than the parental population. Selecting for lower sodium did not affect the concentration of potassium or amino-nitrogen, two other naturally-occurring constituents of sugarbeet that interfere with sucrose extraction. Roots of F1025 are tapered (broad elliptical) and unbranched with a relatively shallow grove and white skin and flesh. F1025 is a multigerm diploid line that segregates for hypocotyl color in a ratio of approximately 90 green to 10 red. No bolters were observed in field trials. F1025 is moderately resistant to Cercospora leaf spot (Cercospora beticola) and susceptible to Rhizoctonia crown and root (Rhizoctonia solani) rot and Aphanomyces root rot (Aphanomyces cochliodes). The sucrose concentration of F1025 was 19 g/kg less than an adapted hybrid cultivar; root yield was approximately 50% of the adapted hybrid. | 1902362 | PI 665408 |
| 1 | PI 665409 | 'F1026' | Beta vulgaris L. subsp. vulgaris | North Dakota, United States | W6 | | | 2012 | DEVELOPED | PRE 2012 | | | | | Breeding material | F1026 was selected almost exclusively for low potassium concentration in the mature root. Potassium interferes with sucrose extraction in normal factory operations. Selecting for potassium reduced the average potassium concentration by 27%, in comparisons with the parental population. Selection for lower potassium did not affect the concentration of sodium or amino-nitrogen, two other naturally-occurring constituents of sugarbeet that interfere with sucrose extraction, or sucrose concentration. Roots of F1026 are tapered (broad elliptical) and unbranched with a relatively shallow grove and white skin and flesh. F1026 is a multigerm line with green hypocotyls. No bolters were observed in field trials. F1026 is moderately resistant to Cercospora leaf spot (Cercospora beticola) and susceptible to Rhizoctonia crown and root rot (Rhizoctonia solani) and Aphanomyces root rot (Aphanomyces cochliodes). The sucrose concentration of F1026 was 22 g/kg less than an adapted hybrid cultivar; root yield was approximately 50% of the adapted hybrid. | 1902363 | PI 665409 |
| 2 | PI 665410 | 'F1027' | Beta vulgaris L. subsp. vulgaris | North Dakota, United States | W6 | | | 2012 | DEVELOPED | PRE 2012 | | | | | Breeding material | F1027 was selected almost exclusively for low amino-nitrogen concentration in the mature root. Amino-nitrogen interferes with sucrose extraction in normal factory operations. Selecting for low amino-nitrogen concentration reduced the average amino-nitrogen concentration by 24%, in comparisons with the parental population. Selecting for lower amino-nitrogen did not affect sucrose concentration The potassium concentration of F1027 is lower than the potassium concentration of the parental population and the sodium concentration of F1027 is greater than that of the parental population. Sodium and potassium are two other naturally-occurring constituents of sugarbeet that interfere with sucrose extraction. Roots of F1027 are tapered (broad elliptical) and unbranched with a relatively shallow grove and white skin and flesh. F1027 is a multigerm diploid line that segregates for hypocotyl color in a ratio of approximately 40 green to 60 red. No bolters were observed in field trials. F1027 is moderately resistant to Cercospora leaf spot (Cercospora beticola) and susceptible to Rhizoctonia crown and root (Rhizoctonia solani) rot and Aphanomyces root rot (Aphanomyces cochliodes). The sucrose concentration of F1027 was 19 g/kg less than an adapted hybrid cultivar; root yield was approximately 50% of the adapted hybrid. | 1902364 | PI 665410 |
