Selection based on proper selection indices can be one of the most effective methods for indirect selection of yield and yield components, simultaneously. In order to determination of selection index for improvement of maize yield, 60 single cross maize hybrids were planted in two separate experiments (drought stress and normal conditions) based on randomized complete block design (RCBD) with t...
Confectionery sunflower (Helianthus annuus L.) is one of the valuable crops which less is known about its variability. Fifty sunflower populations have been gathered from different regions of Iran and evaluated for agro-morphological traits in completely randomized design with 10 repetitions under pot conditions. The twenty traits including days from planting to flowering, days from planti...
Di butyl phthalate (DBP) is an environmental contaminant used in the production of plastics, cosmetics and medical devices. Pregnant women may be exposed to DBP through diet and daily consumer products. In present study, the effects of DBP on reproductive function of pregnant mice were investigated. Pregnant females were given DBP through gastric intubation at 0, 250 and 1000 mg / kg body weigh...
Screening genotypes have a crucial role to increase the efficiency of selections in plant breeding program. Therefore, this study was emphasized determine combining ability and association between traits among themselves yield. The experiment conducted at Haramaya University Research Station (Raare) for two years (2018 2019) using 4x7 alpha-lattice design with three replications. Pooled analysi...
Maize (Zea mays) is a major staple crop. Maize kernel size and weight are important contributors to its yield. Here, we measured kernel length, kernel width, kernel thickness, hundred kernel weight, and kernel test weight in 10 recombinant inbred line populations and dissected their genetic architecture using three statistical models. In total, 729 quantitative trait loci (QTLs) were identified...
terminal heat stress is the most widespread heat stress in the world. in order to evaluate the effect of heat stress on yield, yield component, and mopho-phenological traits of barley, 10 barley genotypes including the 2-row genotypes: mahour, khoram, nimrooz, abidar and 6-row genotypes: yousef, rihan 03, izeh, zahak, nosrat, jonoub were tested under normal (optimum sowing date) and heat stress...
In order to investigate the effects of different nitrogen fertilizer levels and water stress during milky and dough stages on grain yield, yield components and water use efficiency of corn hybrid SC 704 (late maturing, non prolific and dent type), a field study was conducted. The factorial design of the study comprised of a randomized complete block with four replications. Four levels of nitro...
Accuracy and random selection of seeds when testing the 1000 weight in laboratory is great importance order to ensure representativeness sample precise information for further packaging process. The aim this research was check whether seed counter selects by shape size there a trend during operation at maximum reduced speed. Ten species different sizes were used. replicates 100 counted counter,...
this study was conducted to determine the effect of cliniptilolite natural zeolite on deficit irrigation stress tolerance on maize cultivar ksc704. the experiment was laid out as a factorial design based on randomized complete block with three replications at seed and plant improvement institute, karaj in 2012. four irrigation levels, including irrigation after 70, 95, 120 and 145 mm cumulative...
the evaluation of gene bank germplasm collection for morpho-physiological traits is important in the breeding programs. although phenotypic variation was considered, it is likely that this phenotypic variation is largely genetic and therefore directly useable for breeders, especially for those traits with high heritability such as heading and maturity time, plant height, kernel number and weigh...
