Abstract Applications of plant growth regulators such as paclobutrazol (PAC) to grain maize frequently caused depressions in yield. This negative impact probably originated from treatments at an early stage during ontogenesis when the determination potential kernel number coincided with time regulator application. However, stability yield itself is high relevance, and it also key determinant fo...
A two-year study (2007-2008) was carried out to explore the effect of split application of nitrogen fertilizer on yield, dry matter and harvest index of Marfona potato cultivar in Isfahan Agricultural Research Center, Iran. A randomized complete block design with a split plot arrangement with three replications was used. The main plots were three levels of nitrogen (100, 200 and 300 kg ha-1) an...
The objective of this study was to develop a Korean version of the Assessment of Spondyloarthritis International Society-Health Index/Environmental Factor (ASAS HI/EF) and to evaluate its reliability and validity in Korean patients with axial spondyloarthritis (SpA). A total of 43 patients participated. Translation and cross-cultural adaptation of the ASAS HI/EF was performed according to inter...
The most desirable approach to improve characteristics such as yield with polygenic inheritance and genotype × environment interaction, is simultaneous selection using selection index based on related traits. This study was conducted Research Farm of Isfahan University of Technology, to compare selection indices for barley yield improvement under nitrogen stress and non stress conditions, usi...

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...
