Stock number: BGS 626
Locus name: Scirpoides leaf-a
Locus symbol: scl-a
Previous nomenclature and gene symbolization:
Scirpoides leaf-6 = scl.6 (3).
Scirpoides leaf-1 = scl.1 (3).
Scirpoides leaf-2 = scl.2 (3).
Scirpoides leaf-4 = scl.4 (3).
Scirpoides leaf-1 = scl.1 (3).
Scirpoides leaf-2 = scl.2 (3).
Scirpoides leaf-4 = scl.4 (3).
Inheritance:
Monofactorial recessive (2).
Located in chromosome 1HL (1), scl-a.6 is associated with SNP markers 1_0433 to 1_0396 (positions 139.25 to 143.47 cM) in 1HL in Bowman backcross-derived line BW778; scl-a.6 is associated with SNP marker 2_0780 (position 154.89 cM) in 1HL in Bowman backcross-derived line BW775; associated with SNP markers 1_0006 and 2_1126 (position 110.10 cM) in 1HL in Bowman backcross-derived line BW776 (1), likely in 1H bin 11.

Description:
Leaf blades of scl-a plants are folded inward and are narrow compared to those of normal sibs. Folding of the leaf blade persists until maturity (2, 3). Plants of Bowman backcross-derived line BW778 were slightly shorter than Bowman, kernels were slightly thinner and lighter, and grain yields were about 20% lower. Plants of BW778 have inward folded leaf blades that are about 2/3 as wide as those of Bowman (2). The mutant stocks scl.1, scl.2, and scl.4 are alleles based on allelism tests (2). Their phenotypic similarities to the scl-a.6 mutant and SNP markers retained in the same region of 1HL suggesting they are alleles at the scl-a locus (1, 2).
