BGS 85, Yellow streak 4, yst4
Stock number: BGS 85
Locus name: Yellow streak 4
Locus symbol: yst4
Previous nomenclature and gene symbolization:
None.
Inheritance:
Monofactorial recessive (3).
Located in chromosome 2HL (3); yst4.d is located near the vrs1 (six-rowed spike 1) locus (2), in 2H bin 07 near RFLP marker CDO537 (5). An incorrect seed lot was used for analysis of retained SNP markers in the Bowman backcross-derived line for yst4.d, BW927, by Druka et al. (1).

Description:
Plants have a yellow-green color with numerous, vertical yellow streaks in the leaves. The yellow-green color is retained until maturity, but the yellow streaks may be difficult to observe after heading. Plant vigor and height are reduced, heading is delayed, and seed yields are low (4). Plants of the Bowman backcross-derived line for yst4.d, BW927, headed 3 to 5 days later than Bowman and were on average much shorter, 62 vs. 91 cm. Kernels were smaller and lighter, 36 vs. 58 mg. Grain yields of BW927 were 1/3 to1/2 of those for Bowman (4).
