Breeding to raise yield potential through enhancing photosynthesis will have limited impact unless harvest index (HI: proportion of above-ground biomass as grain yield) is maintained or ideally increased. Boosting dry matter (DM) partitioning require increased allocation assimilates sink organs enhance spike growth. A high spring wheat panel 150 genotypes encompassing elite, landrace-derived an...
Abstract Background The harvest index (HI) is a measure of the biological success forming harvestable products. However, our understanding genetic basis HI in rice ( Oryza sativa L.) limited, because it complex trait consisting various yield-related traits and physiological attributes. YTH183 high-yielding line with large panicles high derived from cross between Indica Group variety IR 64 NPT 6...
Sesame is an important oilseed crop in India. To determine potential traits and selection criteria for yield improvement, ninety sesame (Sesamum indicum L.) genotypes were studied in a randomized complete block design with three replications. The data collected on 13 characters were subjected to three different analyses. In variability analysis, high heritability was accompanied by a high genet...
thirty-three M7 soybean mutant lines which originated by γ ray (co-60) from cultivar L17 irradiated with doses150, 200 and 250 Gray (absorbed dose), L17 cultivar and two commercial cultivars Clark (CL) and Williams (WI) were evaluated in view of some agronomical and morphological traits under completely randomized design with three replications. In M7 mutant lines all traits except number of s...
This research was conducted at Research Farm of Isfahan University of Technology to examine the relations among phonologic, morphologic and physiologic traits and their effects on grain yield of 20 oat (Avena sativa L.) genotypes. A randomized complete block design with three replications was used in each irrigation treatment (i.e. irrigation after 70±3, and 130±3 mm evaporation from class A ...
The assessment of crop water productivity (CWP) is practical significance for improving regional agricultural use efficiency and conservation levels. remote sensing method a common estimating large scale CWP, the errors in CWP by originate mainly from inversion yield evapotranspiration (ET). phenological period important factor ET estimation. coefficient (Kc) harvest index (HI), which are close...
Water limitation is a major yield limiting factor in groundnut and transpiration efficiency (TE) is considered the main target for improvement, but TE being difficult to measure it has mostly been screened with surrogates. The paper re-explore the contribution of TE to grain yield in peanut by using a novel experimental approach in which TE is measured gravimetrically throughout the crop life c...
This study was conducted in Research Farm of Isfahan University of Technology to evaluate some of the agronomic and physiological traits and grain yield potentials of ten bread wheat cultivars using a split plot design with three replications. Main and sub plot consisted of optimum and stress moisture treatments (irrigation after 70±3 and 130±3 mm evaporation from class A pan) and wheat cultiva...
Background: Mungbean [Vigna radiata (L.) Wilczek] is known as one of the important crop Vigna group. In order to determine morphological traits mungbean, multivariate analysis will provide advantages in selection phase future breeding programs. Multivariate statistical was used and classify these traits. analysis, that includes principal component (PCA) cluster (CA), considered best tool for se...
