In order to assessment of quality traits of durum wheat lines, 18 elite lines selected from advanced regional durum wheat yield trial, ARDYT (2009-10) along with two check {including Dena(durum wheat) and Parsi (Bread wheat)} were studied in an experiment using RCBD with three replications at Isfahan research station in two consecutive crop season. Results showed a significant difference betwee...
Twenty one F2 progenies derived from a 7×7 diallel crosses along with parents were evaluated for grain yield, flowering and maturity time. Due to significant genotypic effects for all traits, genetic analyses were performed on F2 progenies including analyses of combining ability and genetic components. The Analysis of variance revealed that both additive and non-additive genetic effects were in...
To study drought stress effect on grain quality properties of wheat, an experiment was conductedusing 169 recombinant inbreed lines (RILS) under water stress and non-stress condition and with two separated lattice designs. Grain yield, protein yield, protein content, volume of Zeleny sediment, grain hardness, water absorption, grain moisture content and grain dry matter were evaluated. Analysis...
The relationship between some important morphological traits with seed yield in 18 soybean genotypes inclusive three cultivars (JK, May and Cap) and 15 M4 mutant lines were investigated using randomized complete block design with four replications. Results of analysis of variance indicated that there were significant differences between genotypes in all traits except the number of branches per ...
Improvement of seed yield and oil content in safflower (Carthamus tinctorius L.) as an oilseed crop is the main objective of its breeding programs. However, little genetic information is available for these traits. The main objective of this study was to estimate genetic parameters for seed yield and oil content. Six safflower lines each derived from different Iranian local populations and Saff...
A New QTL for Plant Height in Barley (Hordeum vulgare L.) Showing No Negative Effects on Grain Yield
INTRODUCTION Reducing plant height has played an important role in improving crop yields. The success of a breeding program relies on the source of dwarfing genes. For a dwarfing or semi-dwarfing gene to be successfully used in a breeding program, the gene should have minimal negative effects on yield and perform consistently in different environments. METHODS In this study, 182 doubled haplo...
Information on genetic variability and heritability of plant attributes and their correlation with lint yield and fiber quality is important for planning breeding and selection strategies for prediction of genetic gains in cotton breeding programs. For these purpose, a field experiment was carried out using randomized complete block design with four replications in 2016 and 2017 at Hashem-Abad ...
In order to study the relationships among agronomic traits and yield components in some breeding lines of safflower (Carthamus tinctorius L), this experiment was conducted in a randomized complete block design with three replications in 2009, at the Research Farm of Isfahan University of Technology located in Falavarjan, Isfahan, Iran. Twenty genotypes of safflower were planted in this experime...
Genetic progress in quantitative traits can be improved by understanding how genes interact and estimating the consequences of combining abilities. As a result, randomized block design with three replications was used to conduct forty crossings using line X tester mating ten lines four testers. All qualities were shown highly variable based on ANOVA (analysis variance) results among lines, test...
Development of high yielded varieties is important to balance between production rates and grewing food needs of human population. For genetic analysis of yield and some important traits in oilseed rape (Brassica napus L.), We conducted line×tester analysis with ten lines and ten testers (three winter parents and seven spring parents). First generation hybrids as well as 20 parents (120 genotyp...
