BGS 445, Eceriferum-yb, cer-yb
Stock number: BGS 445
Locus name: Eceriferum-yb
Locus symbol: cer-yb
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (5).
Located in chromosome 2HL (3); cer-yb.200 is near the Gth1 (Toothed lemma 1) locus based on linkage drag (3); cer-yb.200 is associated with SNP markers 2_0647 to 1)1533 (positions 85.71 to 141.56 cM) in 2H bins 07 to 10 of the Bowman backcross-derived line BW133 (1), likely in 2H bin 09.
Description:
Surface wax coating on the leaf blade appears absent (wax code ++ ++ -) (5). Plants of the Bowman backcross-derived line with cer-yb.200, BW133, headed 2 to 3 days later than Bowman and had 4 to 5 more kernels per spike. Other morphological traits of BW133 were similar to those of Bowman (2).
Origin of mutant:
A neutron induced mutant in Bonus (NGB 14657, PI 189763) (4).
Mutational events:
cer-yb.200 (NGB 111086, GSHO 1535) in Bonus (NGB 14657, PI 189763), -yb.316, (NGB 111203), -yb.453 (NGB 111341) in Foma (NGB 14659, CIho 11333) (5); cer-yb.1174 (NGB 112062) in Kristina (NGB 1500, NGB 14661) (6); cer-yb.1211 (NGB 112099) in Kristina (7).
Mutant used for description and seed stocks:
cer-yb.200 (NGB 111086, GSHO 1535) in Bonus; cer-yb.200 in Bowman (PI 483237)*6 (GSHO 1896); cer-yb.200 in Bowman*7 (BW133, NGB 20539).
