(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 584501 | C-33 | Trifolium hybridum L. | Colorado, United States | NLGRP | | Not Available | 1994 | DEVELOPED | 11/30/1994 | | | | | Genetic material | Self-compatibility due to the Sf factor. This factor, and allele to the multiple S series of alleles, is inherited as a simple Mendelian character. Percent of florets setting seed for the self-compatible F1 plants ranged from 70 to 90. All plants contributing seed to this genetic stock were self-compatible, i.e., SfSf or SfSx. | 1482673 | PI 584501 |
| 1 | PI 584502 | C-34 | Trifolium hybridum L. | Colorado, United States | NLGRP | | Not Available | 1994 | DEVELOPED | 11/30/1994 | | | | | Genetic material | Self-compatibility reaction has both gametophytic and sporophytic characteristics. Self-compatibility postulated to be due to a factor, nonallelic to, but modifying the S locus. This locus was designated as the A locus and was inherited independently of the S locus. The A1 allele and an allele of the S locus (S1) interacted to change the compatibility reaction of the pollen from self-incompatibility to self-compatibility. Percent of florets setting seed for the self-compatible F1 plants ranged from 41 to 67. | 1482674 | PI 584502 |
| 2 | PI 584503 | C-35 | Trifolium hybridum L. | Colorado, United States | NLGRP | | Not Available | 1994 | DEVELOPED | 11/30/1994 | | | | | Genetic material | Two inbred clones were self-incompatible at greenhouse temperatures, however, 1 to 2 days at constant 32 deg. C changed the compatibility reaction from self-incompatible (less than 5% of the florets setting seed) to self-compatible (60% or more of the florets setting seed). Twenty-four hours at 21 deg. C reverted the self-compatibility reaction to its original self-incompatible status. Inheritance studies demonstrated that the temperature-sensitive data were interpreted best by a two-gene model with an interaction between S allele genotype and temperature sensitivity. | 1482675 | PI 584503 |
