Genetic analysis of slow-rusting resistance to leaf rust in durum wheat
Leaf rust (caused by Puccinia triticina Eriks.) is a widespread disease of wheat (Triticum spp.) that can be controlled effectively through the use of genetic resistance. Little is known about the slow-rusting type of resistance to leaf rust in durum wheat [Triticum turgidum L. ssp. durum (Desf.) Husn.]. The genetic basis of slow-rusting resistance was investigated in eight International Maize ...

Allelic variants at the Psy-A1 and Psy-B1 loci in durum wheat and their associations with grain yellowness
Phytoene synthase (PSY) genes are involved in the biosynthesis of carotenoid pigments in durum wheat [Triticum turgidum L. subsp. durum (Desf.) Husn.], significantly influencing grain yellowness. This study was conducted to identify new allelic variants at the Psy-A1 and Psy-B1 loci in durum wheat, and to evaluate the applicability of functional markers developed from common wheat (Triticum ...

Effect of height on the competitive ability of wheat with oats
Competitive ability of wheat is influenced by a range of attributes such as plant height, tiller number, and light interception. This study focused on the effect of plant height on weed competitiveness of a set of near-isogenic wheat lines (NILs). The set included seven bread wheat (Triticum aestivium L.) and six durum wheat (T. turgidum L.) cultivars, each having a semidwarf and tall ...

Inhibition of seed germination and seedling growth of Triticum aestivum L. by industrial wastewaters
The present study was undertaken to determine the effect of different concentrations of wastewaters treated with Pseudomonas putida on various growth indices of durum wheat (Triticum aestivum L.) seeds. Significant decreases in terms of root and leaf growth were observed. The phytotoxicity of textile wastewater was more pronounced on initiation times, germination percentages, root and leaf ...

Spring wheat and durum yield and disease responses to copper fertilization of mineral soils
Copper deficiency has been linked to the incidence of a number of wheat diseases. Canadian research on mineral soils has suggested that low Cu availability, as indicated in a DTPA extraction soil test, combined with low soil organic C and coarse textures may also result in Cu deficiency of cereals. The objective of this study was to determine the yield responses of spring wheat (Triticum aestivum ...

Changes In Yield And Carbon Isotope Discrimination Of Italian And Spanish Durum Wheat During The 20th Century
This study evaluates the breeding of durum wheat (Triticum turgidum L. var. durum) during the 20th century with respect to yield and grain carbon isotope discrimination (), and their relationship with plant height, harvest index (HI), days from sowing to anthesis, and days from anthesis to maturity. Twenty-four cultivars released before 1945 (old), between 1950 and 1985 (intermediate), and ...

Analysis of Genotype X environment interactions for grain yield in durum wheat
Genotype x environment (GE) interactions are important sources of variation in crop breeding programs. The objectives of this study were (i) to analyze GE interactions on grain yield of one bread wheat (Triticum aestivum L.) and 19 durum wheat [T. turgidum L. subsp. durum (Desf.) Husn.] genotypes by the additive main effects and multiplicative interaction (AMMI) model, and (ii) to evaluate ...

Haploidy in cultivated wheats: induction and utility in basic and applied research
The usefulness of haploid plants in basic research in cytogenetics, genetics, evolution, and practical plant breeding is well known. Haploid plants provide an efficient research tool for studies on induced mutagenesis and genetic transformation. They also help elucidate the genetic control of chromosome pairing inherently present in allopolyploids such as bread wheat, durum wheat, and oats. ...

Evaluation and characterization of seedling resistances to stem rust ug99 races in wheat–alien species derivatives
Stem rust (caused by Puccinia graminis Pers.:Pers. f. sp. tritici Eriks. & E. Henn.), a devastating disease of wheat (Triticum aestivum L.), was effectively controlled worldwide for the past 50 yr by deployment of stem rust resistance (Sr) genes in wheat cultivars. However, a new stem rust race, TTKSK (known as Ug99 or TTKS) that emerged in eastern Africa, is a cause of concern because it has ...

Breeding effects on grain filling, biomass partitioning, and remobilization in mediterranean durum wheat
This work assesses the changes resulting from durum wheat (Triticum turgidum L. var. durum) breeding in Italy and Spain during the 20th century on grain filling, biomass production, and allocation at anthesis, and the remobilization of preanthesis photosynthates to the grain of main stems. Field experiments, involving 12 Italian and 12 Spanish cultivars released at different periods, were ...

A decision tool for sustainable agricultural policies: the case of water saving scenarios for Apulia Region (Southern Italy)
The economy of Apulia Region largely depends on agriculture but the scarce water resources are the main factor threatening the sustainable production of this sector. This paper describes a geographical information system (GIS) based water balance tool that integrates maps of crops, climate and soil parameters with various scenarios of cropping pattern and farming practice changes. The aim is ...

Effects of the chromosome region including the Gpc-B1 locus on wheat grain and protein yield
The recent cloning of the Gpc-B1 gene from Triticum turgidum ssp. dicoccoides (Körn. ex Asch. and Graebn.) Thell. (DIC hereafter) chromosome 6BS revealed that modern wheat varieties have a nonfunctional allele. The DIC allele accelerates senescence and increases grain protein concentration (GPC) relative to the nonfunctional allele, but its effect on yield is not known. Here we describe the ...

Growth and yield response of rice varieties to foliar application of Boron | JBES 2020 @environmentalxpart
Abstract A field experiment was conducted during the Kharif season of 2018-19 at Rice Research Station Bahawalnagar on the calcareous sandy loam soil to assess the effect of foliar application of boron on growth & yield components of rice varieties (Kissan & Punjab Basmati 2016).The foliar application of boron aqueous solution was used as treatments comprised of control, 0.5kg/ha, ...
