Abstract

The overall objective of the research is to develop molecular markers which can be used in spring barley breeding. The aim of this study was to summarise phenotyping data from recombinant inbred line (RIL) populations for mapping the QTLs for resistance to pre-harvest sprouting and Fusarium head blight (FHB) as well as content of β-glucans. The field and laboratory experiments were performed at the State Priekuli Plant Breeding Institute and at the State Stende Cereal Breeding Institute for two seasons (2010–2011). The mapping populations for pre-harvest sprouting consist of 93 (RILs produced from a cross between hulless barley (HB) breeding line ‘PR 3642’ (susceptible) and HB variety ‘CDC Rattan’ (resistant), and of 94 RILs from a cross between HB variety ‘CDC Freedom’ (susceptible) and hulled variety ‘Samson’ (resistant). Eighty-six RILs for mapping resistance to FHB were derived from a cross between ‘Fontana’ (susceptible) and ‘ND 16461’ (resistant). The content of β-glucans was evaluated in 106 RIL population developed from the spring barley cross of HB lines ‘KM-1910’ (low content of β-glucans) and ‘KM-2084’ (high) and in 117 RILs developed from cross of hulled variety ‘Justina’ (low content of β-glucans) and ‘KM-2084’ (high). The noticeable variation among the recombinant inbred lines is found for all evaluated traits.

Abstract

Wheat was the last of the agriculturally important cereals to be transformed. The ability to introduce genes into wheat remains a technically demanding and relatively inefficient process, mainly confined to culture-responsive but commercially irrelevant genotypes such as Bobwhite. IACR-Rothamsted has developed robust transformation protocols, and in recent years, produced over four hundred independently transformed wheat lines in a wide range of commercial varieties, including Imp, Buster and Rialto. In this paper we summarise our wheat transformation protocols and describe our initial findings from two transformation projects that investigate the role of key proteins in regulating gibberellin biosynthesis and dormancy which have potential to improve end-use quality of bread wheat by reducing pre-harvest sprouting (PHS).
