Sorghum (Sorghum bicolor) known as a Camel crop of cereals, is among the dominant staple food grains for majority Ethiopians. Forty nine sorghum genotypes (hybrids + open pollinated varieties) were tested at five locations in simple lattice design with two replications during 2016 main cropping season. The objectives this study to determine yield stability using univariate methods and assess as...

Drought occurrence is one of the most important reasons for reduced yield in crops. At least in arid and semi-arid areas an efficient approach to tackle this problem is to identify and grow tolerant genotypes with the help of drought tolerance indices. The main objective of this research was to study the effects of drought on the performance of six genotypes of lentil in order to evaluate some ...

Genotype-by-environment (GEI) analysis guides the recommendation of best-performing crop genotypes and production environments. The objective this study was to determine extent GEI on seed yield in tepary bean for genotype cultivation drought-prone Forty-five genetically diverse were evaluated under non-stressed drought-stressed conditions two seasons using a 9 × 5 alpha lattice design with thr...

Durum wheat is the most widely grown cereal in Tunisia, but its production threatened by drought, which exacerbated climate change. This study aimed to identify drought-tolerant durum genotypes from five modern varieties and six landraces a multi-environment trial at two sites (Kef Siliana, Tunisia) during three growing seasons under rainfed irrigated conditions. Six drought tolerance indices (...

Abstract Alkylbenzenes are major aromatic constituents of real transportation fuels and important surrogate components. In this study, 4 kinds C8H10 8 C9H12 alkylbenzenes were tested in a laminar diffusion flame to investigate the influence chemical structure on sooting tendency. The laser induced incandescence (LII) technique was applied obtain 2D distribution soot volume fraction for calculat...

in order to determine yield stability and evaluation of genotype × environment interaction, 20 spring bread wheat promising lines and varieties were studied in a randomized complete block design with three replications in four warm and dry stations (ahwaz, dezful, darab, & khorramabad) during 2002-2004. chamran cultivar was a check in two years trial. the results revealed that the grain yield o...

    In order to investigation of genotype - environment interaction is essential for selecting compatible and stable genotypes in plant breeding. For this order analysis of genotype × environment interaction and identify barley stable genotypes for warm and humid regions, this study conducted in a randomized complete block design with 4 replications and 16 genotypes with two check cultivars in ...

Different responses of plant genotypes to the change of environmental conditions have been the most important and challenging issue for plant breeders and agronomists for the selection of superior genotypes. Cumin is one of the most important medicinal and aromatic plants in Iran that are strongly affected by varying environmental conditions. This study was aimed to investigate E×SD interaction...

Time-resolved soot and PAH formation from gasoline diesel spray pyrolysis are visualized quantified using diffuse back illumination (DBI) laser induced fluorescence (LIF) at 355 nm, respectively, in a constant-volume vessel 60 bar 1400 to 1700 K for up 30 ms. The delay, maximum rate, yield of PAHs compared across fuels temperatures correlated with the sooting indices on either mass or mole basi...
