However, the consensus was that there was no reason to maintain 2 accessions of a 4N 'Hall'. Therefore, 'Hall 4N #3' (RRUT 252) was retained and this accession 'Hall 4N #2' was de-accessioned effective 11/2006. (RR Krueger, 11/2006) | 1830331 | RRUT 251 |

Howver, the consensus was that they were nucellar selections or propagations and therefore redundant. Consequently, 'Ruvel nucellar #1' (RCRC 4142) was retained and 'Ruvel nucellar #2' (RRUT 236) was de-accessioned effective 11/2006. (RR Krueger, 11/2006) | 1830312 | RCRC 4142 |

This accession was retained in order to maintain a budsource of a 4N 'Hall', whereas 'Hall 4N #2' (RRUT 251) was de-accessioned effective 11/2006. (RR Krueger, 11/2006) | 1830332 | RRUT 252 |

See comments in Frost (1948) p 839 implying that 'Rufert' was a type of seedling rather than a variety. The consensus was that only one example or accession of 'Rufert' needed to be maintained. Therefore, 'Rufert A' (RCRC 4141) was retained and 'Rufert C' was de-accessioned effective 11/2006. (RR Krueger, 11/2006) | 1830335 | RRUT 258 |
