Comment
Single factor effects on hardness were found for chromosomes 2A, 2D, 5B and 6D, and interactive effects were found for chromosomes 5A, 6D and 7A {1414}. The addition of King II rye chromosome 5R converted Holdfast wheat from hard to soft {470}. A 14.5 kD rye analogue was also isolated from 6x triticales which have soft texture {470}. All ryes are thought to have soft texture. Two genes for grain hardness were reported in {055}. Hard and soft NILs are listed in {0298}. QTL: In a DH population of Courtot/CS a major locus in chromosome 5DS coincided with Ha; minor QTLs mapped in chromosomes 1A (associated with Xfba92-1A) and 6D (associated with Xgwm55-6D) {0141}. Ten QTLs for kernel hardness (54% of the variation) were mapped in 'Forno'/ 'Oberkulmer' spelt {0280}. Two QTLs were detected for grain hardness in RILs of the ITMI population (Synthetic / Opata 85) {10051}. The QTL on the short arm of chromosome 5D was associated with Xmta10-5D, and increased hardness was contributed by Opata {10051}. The locus located proximally on the long arm of 5D was associated with Xbcd450-5D and increased hardness was contributed by the Synthetic allele {10051}. Two QTLs, QHa.ksu-3B, associated with Xksum9-3B (R2=0.09, and QHa.ksu-5D(Ha), associated with Xcfd-5D (R2=0.3), were identified in Karl*2/TA 4152-4 {10273}.
