Effect of ppd-a1 and ppd-b1 allelic variants on grain number and thousand kernel weight of durum wheat and their impact on final grain yield
The main yield components in durum wheat are grain number per unit area (GN) and thousand kernel weight (TKW), both of which are affected by environmental conditions. The most critical developmental stage for their ...
Characterization and mapping of leaf rust resistance in four durum wheat cultivars
(Public Library of Science, 2018)
Widening the genetic basis of leaf rust resistance is a primary objective of the global durum wheat breeding effort at the International Wheat and Maize Improvement Center (CIMMYT). Breeding programs in North America are ...
Effect of Ppd-1 genes on durum wheat flowering time and grain filling duration in a wide range of latitudes
(Cambridge University Press, 2016)
Understanding the effect of genetic factors controlling flowering time is essential to fine-tune crop development to each target environment and to maximize yield. A set of 35 durum wheat genotypes of spring growth-habit ...
Changes in durum wheat root and aerial biomass caused by the introduction of the Rht-B1b dwarfing allele and their effects on yield formation
(Springer Verlag, 2016)
Aims: This study aimed to quantify the changes in root and aerial biomass of durum wheat brought about by the introduction of the Rht-B1b dwarfing allele and their effects on yield formation. Methods A historical series ...
Mapping of genetic loci conferring resistance to leaf rust from three globally resistant durum wheat sources
Genetic resistance in the host plant is the most economical and environmentally friendly strategy for controlling wheat leaf rust, caused by Puccinia triticina Eriks. The durum wheat lines Gaza (Middle East), Arnacoris ...
Effect of Ppd-1 photoperiod sensitivity genes on dry matter production and allocation in durum wheat
Understanding the effect of genetic factors controlling flowering time is essential to fine-tune phenological development and to maximize yield. Thirty-four spring durum wheat genotypes classified in five allelic combinations ...
