Genetic Heritability for Grain Yield and Its Related Characters in Spring Wheat (triticum Aestivum L.)
Seven F3 progenies and their 8 parental lines of spring wheat were evaluated for some genetic parameters viz., coefficient of variability (Cv), genetic variance (Vg), heritability percentage (h %) and genetic advance (GA) in 7 quantitative characters (grain yield and its associated traits). Highly significant (p≤0.01) differences were observed for all the characters viz. plant height, number of...
متن کاملGrain Filling Rate and Duration in Bread Wheat Under Irrigated and Drought Stressed Conditions
Abstract Eleven wheat cultivars were evaluated at 10-day intervals, beginning from anthesis, under irrigated and drought stress conditions during 2006-2007. The effects of irrigation, genotype and date of harvest were significant for most of the studied characters. Water deficit decreased pre-and post-anthesis assimilation rate, grain weight per spike, grain number per spike and 1000 grain wei...
متن کاملIdentification and evaluation of endogenous control genes for use in quantitative RT-PCR during wheat (Triticum aestivum L.) grain filling.
The use of appropriate reference genes is essential for the generation of accurate and biologically meaningful results from quantitative real-time PCR (qRT-PCR) analysis. However, studies have found that the expression of most commonly used reference genes is not always independent of the tissues, treatments, or developmental stages studied. geNormPlus, NormFinder, and BestKeeper, were applied ...
متن کاملEffect of Salinity Stress on Grain Yield and Grain Quality in Wheat (Triticum aestivum L.) Lines
The effects of salinity stress on grain quality traits of wheat were investigated using 180 lines of F5 generation in two environments (normal and salinity stress). A randomized complete block designs with three replications was used in each of the environments at the Research Farm of the Agricultural and Natural Resources Research Station of Isfahan in 2019-2020 cropping season. Grain yield, p...
متن کاملStudy of Water Relations, Chlorophyll and their Correlations with Grain Yield in Wheat(Triticum aestivum L.) Genotypes
The objective of this experiment was to study of water relations and chlorophyll in different wheat genotypes and their correlations with grain and biological yields. 21 genotypes of bread wheat were compared in a field experiment as randomized complete blocks design with four replications. The results showed that relative water deficit, relative water loss, excised leaf water retention, cell m...
