“…The CV for the majority of traits was less than 20%. In general, CV value higher than 20% is considered to be high; however, it may be possible to ignore the high CV values when F test is significant and this item is found in several published research works (Okwuagwu et al, 2008;Kandic et al, 2009). The inconsistent CV values reported in many studies might be due to physio-genetic characteristics and degree of compatibility of the plant material, low number of sampled individuals per genotype in plot, low number of replications per genotype and/or variable environments in which the trial was carried out (Okwuagwu et al, 2008).…”

Chickpea (Cicer arietinum L.), a cool season grain legume, serves as an important cheap source of protein and energy in developing countries, and plays an important role in the enrichment of soil fertility. In order to identify simple sequence repeat (SSR) markers associated with agro-morphological traits in chickpea, 44 genotypes comprising cultigen, landraces, internationally developed improved lines and wild relatives, were phenotyped for several agro-morphological traits in a randomized complete block design with three replications at Urmia Rainfed Research Station. High genetic variability was observed among the chickpea genotypes for the studied agro-morphological traits. In molecular experiment, genetic variability among genotypes was assessed by using SSR markers. One hundred alleles were generated at 16 SSR loci, with a mean number of alleles per locus of 6.25. Using general linear model (GLM) and applying multiple testing corrections, 10 SSR loci associated with the genes controlling the studied agro-morphological traits were identified. Some identified markers were associated with more than one trait. The identified markers could be of great interest in marker assisted selection (MAS) in chickpea breeding programmes.

“…Their results of path analysis indicated in all of moisture conditions, the biggest direct effect on stress tolerance index was related to grain yield. Kandic et al (2009) indicated early vigor, early maturity and leaf senescence were found to be suitable for wheat breeding under different moisture regimes.…”

“…Some of researchers indicated that the positive correlation between grain yield and yield component traits in wheat such as harvest index (Ghaderi et al, 2009), biological yield (Ghaderi et al, 2009;Kandic et al, 2009), number of spike per square meter (Leilah and Al-Khateeb, 2005), plant height (Leilah and Al-Khateeb, 2005), grains per spike (Khan et al, 2010) and 1000 kernel weight (Leilah and Al-Khateeb, 2005).…”

Path and correlation analysis were executed to investigate the relationships between grain yield and other important yield components in bread wheat (Triticum aestivum L.) genotypes during two years (2009)(2010)(2011) under supplemental irrigation and dryland conditions. Field experiments were performed in a randomized complete block design with four replications. Grain yield showed positive correlation with plant height and test weight under supplemental irrigation condition. The similar results were also revealed between grain yield and plant height, spike length, days to maturity, agronomic score and test weight in dryland environment. The grain yield of bread wheat in dryland condition depended on the effect of plant height, days to maturity, agronomic score and 1000 kernel weight, whereas in supplemental irrigation was mainly related to plant height, spike length, 1000 kernel weight and test weight. The influence of 1000 kernel weight on grain yield in both environments seems to cause from the fact that grain yield in wheat is frequently the sink limited, and for this reason, the 1000 kernel weight has been reported as a promising trait for increasing grain yield in wheat under different conditions. The nearly equal value of correlation and path coefficients of plant height and grain yield showed plant height had positive and direct effect on grain yield, in both conditions and suggesting a criteria trait for improving of grain yield. The results showed that genotype 12 (CS/TH.SC//3*PVN/3/MIRLO/BUC/4/MILAN/5/ TILHI) is a high yielding potential genotype in moisture limited conditions.

“…The low broad sense heritability magnitude revealed traits under examination had lower genetic potentials. Kandic et al (2009) suggested that the heritability of physiological traits is lower than the heritability of morphological traits. Similar trends were showed by relative water content and leaf succulence traits depicted lower heritability.…”

This study was conducted to investigate the genetic variability of plant growth and physiological characters in thirty wheat genotypes under normal and drought stress conditions. Selection of important plant growth and physiological traits are essential component for wheat yield improvement. For this purpose, an experiment was conducted in the glasshouse during 2012-13 to estimate the extent of genetic components viz., genetic variance, coefficient of variability and broad sense heritability for plant growth and physiological traits under normal and drought stress conditions. Higher genetic variance was observed between the genotypes for the cell membrane stability, excised leaf water loss, relative water content, proline, sugar and glycine betain under both conditions. This suggested that these indices can be used as direct selection criteria for wheat improvement. While excised leaf water loss and fresh root weight revealed the least variability for GCV and PCV correspond to high heritability under stress condition. Hence, these traits can be used as indirect selection criteria under stress condition.
