The main goal of this study was to investigate the genetic basis of yield and grain quality traits in winter wheat genotypes using association mapping approach, and identify linked molecular markers for marker assisted selection. A total of 120 elite facultative/winter wheat genotypes were evaluated for yield, quality and other agronomic traits under rain-fed and irrigated conditions for two ye...

The effect of some weed control treatments (Bifonex, Tribenuron-methyl, hand weeding and unweeded check), five wheat cultivars (Sakha 69, Sids 6, Sids 7, Sids 8 and Sids 9) and their interaction on the productivity of wheat plants and associated weeds were examined under the sandy soil conditions. The obtained data indicated that total dry weight/m2 recorded at 60 days from wheat sowing signifi...

iranian farmers are faced with many challenges. they must be economically efficient, produce enough food for the growing population and must be sensitive to environmental concerns. however, there is a growing concern related to the aftermath and side-effect of some agricultural activities on environment. these concerns made researches to consider agricultural activities with profound care in or...

This research was conducted to study and classify the physico-chemicalproperties of soil, yield components of wheat and to determine the significance ofthese parameters on the grain yield formation. In this research, seven statisticalmethods consisting of simple correlation analysis (SCA), multiple linear regression(MLR), stepwise regression (SR), factor analysis (FA), principal componentanalys...

Wheat (Triticum spp) is one of the first domesticated food crops. It represents the first source of calories (after rice) and an important source of proteins in developing countries. As a result of the Green Revolution, wheat yield sharply increased due to the use of improved varieties, irrigation, pesticides, and fertilizers. The rate of increase in world wheat production, however, slowed afte...

to investigate the effect of supplemental irrigation and nitrogen fertilizer on kernel weight, test weight and wheat grain yield under dryland conditions, a two-year field experiment was conducted in the research farm of college of agriculture, shiraz university during 2004-2005. five irrigation regime including dryland conditions, irrigation at stem elongation, booting, flowering and grain fil...

This study investigated the effect of two forms of Se at three rates (0, 18, and 36 g/ha) on wheat and barley under rain fed conditions. Results showed that spraying application of 18 g/ha Se increased Chl a and Chl a+b contents while the selenium rate 36 g/ha decreased plant pigments. Evaluations of Chl a, Chl b, chlorophyll total a+b, carotenoids, chlorophyll total content, relative water con...

The proper amount of fertilizer application is the main factor affecting grain yield and its components durum wheat. Hence, field experiment was carried out in winter seasons 2017/2018 2018/2019, at Research Farm Faculty Agriculture, Sohag University, to study effects potassium levels (zero, 25, 50 75 kg K2O /fed.) on four wheat genotypes (Bani Suef 6, NGB 7214, 5399 4816). A randomized complet...
