Material type: materialTypeLabelArticlePublisher: 2012ISSN: No (Revista en electrónico); No. In: Wheat Information Service (eWIS) v. 114, p. 1-8Summary: Global trade requires wheat to be classified into hard or soft. The trait is understood to be under the control of ?ha? locus on chromosome 5D. Puroindolines a and b explain the biochemical basis of grain hardness. Several methods to measure grain hardness in wheat have been suggested. Single Kernel Characterization System (SKCS) has now come to be globally accepted as the most appropriate method to screen wheat genotypes for hardness. The paper reports the SKCS hardness score of 111 Indian bread wheat varieties, 174 aestivum genetic stocks and a collection of 35 durum germplasm lines and varieties. Classified into five categories ranging from very soft to very hard, 37.5% of all material screened was categorised as very hard with an SKCS score of over 90. Whereas only five per cent of the material screened was grouped as soft or very soft scoring less than 54 SKCS score.Collection: CIMMYT Staff Publications Collection
