Abstract

Wild emmer wheat in Israel varies not only in genetic polymorphisms of allozymes and DNA markers, but also in quantitative traits of agronomic importance (Nevo 1983a, 1986a, 1989a, 1995, 2001b; Nevo et al. 1984b; Peng et al. 2000c, 2001). These include agronomic traits, disease resistance, protein content, ecological tolerances to drought, salt, herbicides, and photosynthetic yield. These traits, described below, are economically significant and should be conserved and utilized in wheat crop improvement. Our results substantiated earlier claims that wild emmer in Israel displays remarkable morphological and physiological variation both within and between populations in each of the agronomic characters studied (Table 2 and Fig. 1 in Nevo et al. 1984b; Fig. 6.1). These traits are derived by natural selection as adaptive traits at both macro- and microgeographic scales. A detailed quantitative trait loci (QTL) mapping for 11 agronomic traits appears below and is elaborated on in Peng et al. (2001).
