evaluating of agronomic traits and their relationships with grain yield are important in plant breeding. in order to evaluate agronomic traits and their effects on grain yield, 76 durum wheat landraces as well as 4 local checks were studied in augmented design with 4 blocks under rainfed condition in maragheh and ardabil locations. the result showed that there is remarkable diversity among land...

An experiment was carried out to study the variability of leaf anatomical characters of wheat (Triticum aestivum L.) cultivars and their association with grain yields. Results indicated that in most of the cases cultivar differences were significant. In respect of 6th leaf anatomical characters, simple correlation coefficients indicated that most of the leaf anatomical traits had significant ne...

Drought stress is one of the leading constraints to wheat (Triticum aestivum L.) production globally. Breeding for drought tolerance using novel genetic resources is an important mitigation strategy. This study aimed to determine the level of drought tolerance among diverse bread wheat genotypes using agronomic traits and proline analyses and to establish correlation of proline content and agro...

Knowledge of genetic and phenotypic association among economic traits helps plant breeders in outlying efficient breeding strategies for development high yielding wheat variety. An experiment on 238 progenies along with parents was conducted to determine the correlation path coefficient analysis yield its attributing wheat. The result reveals presence variability Grain per had showed significan...

to investigate the yield and agronomic traits of winter bread wheat genotypes in irrigating condition and also to determine the relationship of these traits with grain yield, 15 advanced genotypes of wheat along with three conventional cultivars where studied using randomized complete block design in three replications in 2010 growing season at kheyr-abad agricultural research station. the anal...

We report a case study of natural variations and correlations of some photosynthetic parameters, green biomass and grain yield in Cappelle Desprez and Plainsman V winter wheat (Triticum aestivum L.) cultivars, which are classified as being drought sensitive and tolerant, respectively. We monitored biomass accumulation from secondary leaves in the vegetative phase and grain yield from flag leave...

The grain size is one of the complex trait of rice yield controlled by a plethora of interaction of several genes in different pathways. The present study was undertaken to investigate the influence of seven known grain size regulating genes: DEP1, GS7, GS3, GW8, GL7, GS5 and GW2. A wide phenotypic variation for grain length, grain width and grain length-width ratio were observed in 89 germplas...
