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
(Frontiers in Plant Science, 2018-06-29)
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 ...
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, 2016-01-27)
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 ...
Effect of Ppd-1 photoperiod sensitivity genes on dry matter production and allocation in durum wheat
(Elsevier, 2017-06-21)
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 ...
Agronomic performance of durum wheat landraces and modern cultivars and its association with genotypic variation in vernalization response (Vrn-1) and photoperiod sensitivity (Ppd-1) genes
(Elsevier, 2020-07-17)
This study analyzed the relationship between important agronomic traits and major genes regulating flowering time in a panel of 151 Mediterranean durum wheat landraces and 20 modern cultivars. Field ...
Allelic Variation at the Vernalization Response (Vrn-1) and Photoperiod Sensitivity (Ppd-1) Genes and Their Association With the Development of Durum Wheat Landraces and Modern Cultivars
(Frontiers Media, 2020-06-23)
Wheat adaptability to a wide range of environmental conditions is mostly determined by allelic diversity within genes controlling vernalization requirement (Vrn-1) and photoperiod sensitivity (Ppd-1). ...
Labelling Selective Sweeps Used in Durum Wheat Breeding from a Diverse and Structured Panel of Landraces and Cultivars
(MDPI, 2021-03-24)
A panel of 387 durum wheat genotypes including Mediterranean landraces and modern cultivars was characterized with 46,161 diversity arrays technology (DArTseq) markers. Analysis of population structure ...
Short communication: Emergence of a new race of leaf rust with combined virulence to Lr14a and Lr72 genes on durum wheat
(Instituto Nacional de Investigación y Tecnología Agraria y Alimentaria (INIA), 2016-08-31)
Leaf rust is a foliar disease caused by the fungus Puccinia triticina that may severely reduce durum wheat yield. Resistance to this pathogen is common in modern durum germplasm but is frequently based ...
Effect of allele combinations at Ppd‐1 loci on durum wheat grain filling at contrasting latitudes
(Wiley, 2019-09-15)
Flowering time is the most critical developmental stage in wheat, as it determines environmental conditions during grain filling. Thirty‐five spring durum genotypes carrying all ...
Agronomic, Physiological and Genetic Changes Associated With Evolution, Migration and Modern Breeding in Durum Wheat
(Frontiers Media, 2021-07-08)
A panel of 172 Mediterranean durum wheat landraces and 200 modern cultivars was phenotyped during three years for 21 agronomic and physiological traits and genotyped with 46,161 DArTseq markers. Modern ...
The Effect of Photoperiod Genes and Flowering Time on Yield and Yield Stability in Durum Wheat
(MDPI, 2020-12-07)
This study analysed the effect of flowering time as influenced by photoperiod sensitivity genes on yield and yield stability in durum wheat. Twenty-three spring genotypes harbouring different allele ...
