| 0 | GSHO 597 | des6.i | Hordeum vulgare L. subsp. vulgare | Arizona, United States | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | The chromosomes are paired during pachytene and undergo desynapsis during diplotene. The degree of desynapsis is 7.9 + 2.1 ranging from 7 ring bivalents (d=0) to 14 univalents (d=14). Many univalents split longitudinally during Anaphase I. Lagging chromosomes and micronuclei are observed frequently at Telophase I. Microspore quartets contain an average of 3.3 micronuclei per quartet with a range of 0 to 12. Ovule fertility is about 16%, and about 22% of the selfed seeds are trisomics. Inheritance: Monofactorial recessive. Located in chromosome 1H [5]. Previous nomenclature and gene symbolization: None. Mutational events: des6.i in Betzes; des6.m in OAC 21 (CIho 1740), des6.o in Betzes. Mutant used for description and seed stocks: des6.i in Betzes (GSHO 597). | 1512225 | GSHO 597 |
| 1 | GSHO 592 | des1.a | Hordeum vulgare L. subsp. vulgare | Minnesota, United States | NSGC |  | | 1994 | DEVELOPED | | | | | | Genetic material | The name long chromosomes refers to the frequent occurrence of rod bivalents at metaphase I. The chromsomes are paired during pachytene, but undergo desynapsis during diplotene. The degree of desynapsis is d=2.6+1.6 ranging from 7 ring bivalents (d=9) to 5 rod bivalents plus 4 univalents (d=9). Lagging chromosomes and micronuclei are observed frequently at Telophase I. Microspore tetrads contain an average of 0.3 micronuclei per tetrad with a range of 0 to 6. Ovule fertility is about 45%. Inheritance: Monofactorial recessive. Located in chromosome 7H[1]. Previous nomenclature and gene symbolization: Long chromosome=lc. Mutational events: des1.a in Mars; des1.v in Freja (CIho 7130). Mutant used for description and seed stocks: des1.a in Mars (GSHO 592). | 1512385 | GSHO 592 |
