BGN  41:161 Export to PDF
Stock number: BGS 407
Locus name: Eceriferum-m
Locus symbol: cer-m

Previous nomenclature and gene symbolization:

None.

Inheritance:

Monofactorial recessive (3).
Location in chromosomes 1HL or 3HL (1); cer-m.15 is based on SNP markers retained in the Bowman backcross-derived line BW117 for cer-m.15, between 2_0229 to 2_1126 (positions 106.61 to 110.10 cM) in 1H bin 10 and between 1_0918 and 1_1172 (positions 187.28 to 190.87 cM) in 3H bin 12 (1).

Description:

Surface wax coating on the spike appears reduced or normal, and the wax coating on the leaf sheath and stem is reduced (wax code +/++ + ++) (3, 5). The mutant is a semidwarf (3/4 to 5/6 of normal height) and may be semi-sterile (25 to 50% seed set) (3). Rachis internodes of plants in Bowman backcross-derived line BW117 plants were slightly shorter than those of Bowman. The number of kernels per spike for BW117 was 4 or 6 fewer than for Bowman. Kernel weights and test weights were 10 to 20% lower. Seed yields of BW117 were about 1/3 of those of Bowman (2).

Origin of mutant:

An X-ray induced mutant in Bonus (NGB 14657, PI 189763) (3).

Mutational events:

cer-m.15 (NGB 110899, GSHO 434) in Bonus (NGB 14657, PI 189763) (3, 4).

Mutant used for description and seed stocks:

cer-m.15 ( NGB 110899, GSHO 434) in Bonus; cer-m.15 in Bowman (PI 483237)*6 (GSHO 2192, BW117, NGB 20523).
