In the present study, twenty two selected lines from eleven Iranian eggplant (Solanum melongena L.) landraces along with Varamin landrace, as control, were studied in a randomized complete block design with three replications in three locations (Karaj, Varamin and Dezful). Sum of yield and marketing score for each line was recorded. Analysis of variance for yield showed significant differences ...
Extended Abstract Introductionand Objective: Barley (Hordeum vulgare L.) with a cultivated area of nearly one and a half million hectares and with a production of about three million tons per year after wheat is the main crop in the country. The main objectives of this study were to (i) examine the variation within the barley national germplasm, (ii) compare the introduced germplasm with the...
Genomic selection (GS) unlike marker-assisted backcrossing (MABC) predicts breeding values of lines using genome-wide marker profiling and allows selection of lines prior to field-phenotyping, thereby shortening the breeding cycle. A collection of 320 elite breeding lines was selected and phenotyped extensively for yield and yield related traits at two different locations (Delhi and Patancheru,...
the selection of high yielding varieties with good stability is an important objective in rice breeding programs. the grain yield of eight rice lines with a check (nemat) were compared on six locations of gilan and mazandaran provinces during two years, using rcbd with four replications. combined analysis of variance showed that the effect of variety and year × location × variet...
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
In wheat (Triticum aestivum L.) high temperature (≥30°C) during grain filling leads to considerable reduction in grain yield. We studied 400 multiple synthetic derivatives (MSD) lines to examine the genetic variability of heat stress-adaptive traits and to identify new sources of heat tolerance to be used in wheat breeding programs. The experiment was arranged in an augmented randomized complet...
Genetic diversity of 13 new cereals, primary tritipyrum lines, five triticale lines and nine Iranian bread wheat varieties was studied under the randomized completely blocks design in terms of agronomic and morphological traits. The highley significant difference was observed between genotypes for all traits except in the filamental leaf length, main leaf length and main leaf width. The highest...
Research Article Stability analysis for grain yield and yield components in chick pea (Cicer arietinum l.) Abstract: Twenty one advanced breeding lines selected from All India Coordinated trials and one local popular variety " annegiri' were studied over three years to identify high yielding stable genotypes. Genotype , environment and G x E interaction variance found to be significant. Genotyp...
Rice (Oryza sativa L.) is the most important food crop of the world; but drought stress is a serious limiting factor to rice production and yield stability in rainfed areas. Breeding for drought tolerance is a challenging task because of the complexicity of the component traits, screening technique, environmental factors and their interaction. The major setback in drought tolerance breeding is ...
study of morphological traits in spring wheat genotypes in related to fusarium head blight resistant
good perception of relation-sheep among plant morphological traits and resistance to fusarium head blight of wheat is quite effective to make a good success in plant breeding project. in this experiment this relation has been checked out. the morphological traits were included plant height, peduncle length and spike density. we used 28 spring wheat genotypes and 2 durum genotypes. there was sig...
