Morphogenesis in early generations of winter emmer / durum winter wheat hybrids

Abstract

Morphogenesis profiles in early generations of winter emmer Triticum dicoccum var. atratum (Host) Koern. / modern durum winter wheat varieties hybrids were established. High level and frequency of positive transgressions for the grain weight per spike (53.7% and 85.7%, respectively) and kernel number per spike (53.4% and 57.4%, respectively) in all three combinations were observed. Emmer plants with amber grain and high levels of positive transgressions for all performance traits and plant height of ≤ 80cm. (spike length, spikelet and kernel numbers per spike, grain weight per spike, and 1000-kernel weight) were selected in F2 hybrids between winter emmer / durum winter wheat. The inheritance coefficients varied, depending on the trait and cross combination.
