(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
PI 651649
PI 651650
When searching a range of accessions, use the Advanced Search tab with the Accession Identifier Range criterion.
The more information you provide, the better the search will be.

| 0 | PI 598366 | A317I | Pisum sativum L. | Ontario, Canada | W6 |  | Not Available | 1997 | DEVELOPED | 1997 | | | | | Genetic material | Near-isogenic line. A mutant with less than 6% of the NADH-nitrate reductase (nar1) of the wild type, and exhibits incomplete dominance. Nitrate reductase-deficient seedlings were rescued by inoculation with Rhizobium leguminosarum, and were fertilized with 0.5 mM NH4+ until the root nodules were effective. Propagation must be performed with effectively nodulated plants. This line can be used in agronomic and physiological studies of nitrogen fixation and nitrate metabolism, and as a source of genetic material. | 1546118 | PI 598366 |
| 1 | PI 598367 | nod3I | Pisum sativum L. | Ontario, Canada | W6 | | | 1997 | DEVELOPED | 1997 | | | | | Genetic material | Near-isogenic line. A monogenic recessive mutant. When inoculated with Rhizobium leguminosarum nodule numbers are higher than normal even in the presence of nitrates. This line can be used in agronomic and physiological studies of nitrogen fixation, and as a source of genetic material. | 1546119 | PI 598367 |
| 2 | PI 598368 | A317nod3I | Pisum sativum L. | Ontario, Canada | W6 |  | Not Available | 1997 | DEVELOPED | 1997 | | | | | Genetic material | Near-isogenic line. A double mutant with NADH-nitrate reductase activity (nar 1) that is less than 6% of the wild type (incompletely dominant character), and with a higher than normal number of nodules even in the presence of nitrate (monogenic recessive character). Propagation must be performed with effectively nodulated plants. This line can be useful in agronomic and physiological studies of nitrogen fixation and nitrate metabolism, and as a source of genetic material. | 1546120 | PI 598368 |
| 3 | PI 598369 | E135I | Pisum sativum L. | Ontario, Canada | W6 |  | | 1997 | DEVELOPED | 1997 | | | | | Genetic material | Near-isogenic line. Mutant conditioned by monogenic recessive allele at the sym 13 locus. When inoculated with Rhizobium leguminosarum, forms a normal number of white root nodules lacking nitrogenase activity. Can be used in agronomic and physiological studies of nitrogen fixation and as a source of genetic material. | 1546121 | PI 598369 |
| 4 | PI 598370 | R25I | Pisum sativum L. | Ontario, Canada | W6 |  | Not Available | 1997 | DEVELOPED | 1997 | | | | | Genetic material | Near-isogenic line. A non-nodulating mutant conditioned by a monogenic recessive allele at the sym 8 locus. This line can be used in agronomic and physiological studies of nitrogen fixation, and as a source of genetic material. | 1546122 | PI 598370 |
