The normalized difference vegetation index (NDVI) is gaining popularity as a complementary selection tool, even though it requires an instrument not readily available in the developing world. We evaluated several parameters (originating from the analysis of digital photos using BreedPix software) as potential selection criteria in 23 winter wheat yield trials grown over 4 years at 2 sites. NDVI and digital photos were taken at key development stages from stem elongation to maturity. The correlations between digital photo parameters a and u and grain yield, as well as correlations between NDVI and grain yield within individual trials, varied depending on …

Cereal cyst nematodes (CCNs) are plant parasites that significantly limit global cereal production. The most frequently reported pathogenic species are Heterodera avenae, H. filipjevi, and H. latipons. One of the most cost-effective, environmentally friendly, and easily adopted control measures is the use of genetic host resistance, which maintains nematode populations below the economic damage threshold level. Many effective sources of resistance to CCNs have been identified in cereals; however, their effectiveness and usefulness is dependent on the interaction of the specific putative resistant accession and the CCN pathotype found in a specific region. In this study, 719 wheat lines from …

The present work was a study on the adverse effects of salinity on growth, nodulation, and some physiological parameters in 4 symbiotic combinations involving 2 Moroccan alfalfa (Medicago sativa L.) populations (Demnate and Tata) and 2 rhizobial strains (rhLAr 1 and rhLAr 4). The experiment was conducted in the greenhouse at 32/22 °C day/night, 50%-80% relative humidity, and a photoperiod of 16 h. The seedlings were separately inoculated with suspensions of 2 rhizobial strains and grown under 2 NaCl treatments, 0 mM (control) and 100 mM (salt stress), in plastic pots filled with sterile sand and peat at 9/10 and …
Influence Of Salinity On Growth And Yield Attributes In Chickpea Cultivars, Ranju Singla, Neera Garg
Influence Of Salinity On Growth And Yield Attributes In Chickpea Cultivars, Ranju Singla, Neera Garg
Turkish Journal of Agriculture and Forestry
Seeds of 4 cultivars of chickpea (2 desi, CSG 8962 and DCP 92-3, and 2 kabuli, CSG 9651 and BG 267) were grown under 0, 4, 6 and 8 dS m^{-1} levels of salinity until maturity. Shoot and root dry weights, root shoot ratio and various yield parameters were evaluated under salinity at 40, 70 and 100 days after sowing. Salinity significantly reduced dry matter accumulation in both roots and shoots in all cultivars, though declension was more pronounced in BG 267 (kabuli) and DCP 92-3 (desi). Root growth was more adversely affected than shoot growth, which also had an …

Determination Of The Salt Tolerance Of Some Barley Genotypes And The Characteristics Affecting Tolerance, Seydi̇ Ahmet Bağci, Hasan Eki̇z, Ahmet Yilmaz
Turkish Journal of Agriculture and Forestry
The salt (NaCl) tolerance of 8 barley genotypes was investigated. Plants were grown hyroponically in Hoagland solution at 5 different NaCl concentrations. Germination percentage, shoot and root length, shoot and root dry weight, salt tolerance percentage, and K and Na concentrations in the shoots and roots were evaluated. Salt tolerance percentage, which is calculated from the germination percentage and dry weight production, was the most reliable criterion. On the other hand, with some exceptions, high K concentration and K/Na ratios were other potential criteria. Erginel-90 and WBELT-10 showed high levels of tolerance; and Obruk-86, Anadolu-86, Kıral-97 and Karatay-94 showed medium …

By using two durum wheat cultivars (Triticum durum L. cvs. Balcali-85 and C-1252) a nutrient solution experiment was carried out to study i) genotypic variation in cadmium (Cd) tolerance, ii) Cd concentrations in plants, and iii) the role of ascorbic acid and non-protein SH groups (SH: sulphydryl) in Cd tolerance. Plants were grown under controlled climatic conditions for 15 days and subjected to increasing Cd supply (0, 6, 30, 75 and 150 µM). Of the two cultivars, C-1252 showed greater sensitivity to Cd toxicity as judged from the severity of Cd toxicity symptoms on leaves. Increasing Cd supply markedly reduced …
