Breeding Value of Primary Synthetic Wheat Genotypes for Grain Yield
To introduce new genetic diversity into the bread wheat gene pool from its progenitor, Aegilops tauschii (Coss.) Schmalh, 33 primary synthetic hexaploid wheat genotypes (SYN) were crossed to 20 spring bread wheat (BW) cultivars at the International Wheat and Maize Improvement Center. Modified single seed descent was used to develop 97 populations with 50 individuals per population using first b...
متن کاملGenetic 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 کاملLeaf Anatomical Characters in Relation to Grain Yield of Wheat (triticum Aestivum L.) Cultivars
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...
متن کاملLate-Season Prediction of Wheat Grain Yield and Grain Protein
Pre-harvest prediction of winter wheat (Triticum aestivum L.) grain yield and/or protein could assist farmers in generating yield maps and reliable product marketing. This study was conducted to determine the relationship between spectral measurements (taken from Feekes growth stage 8 to physiological maturity) and grain yield and grain protein. Spectral measurements were taken using photodiode...
متن کاملOverexpression of wheat gene TaMOR improves root system architecture and grain yield in Oryza sativa
Improved root architecture is an effective strategy to increase crop yield. We demonstrate that overexpression of transcription factor gene MORE ROOT (TaMOR) from wheat (Triticum aestivum L.) results in more roots and higher grain yield in rice (Oryza sativa). TaMOR, encoding a plant-specific transcription factor belonging to the ASYMMETRIC LEAVES2/LATERAL ORGAN BOUNDARIES (AS2/LOB) protein fam...
