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...

Investigation was carried out at the Agricultural research Institute, Hyderabad, during kharif 2018-19 with objective of assessing trait association and direct indirect effects yield quality related traits on grain in fifty rice (Oryza sativa L.) genotypes. Among eighteen characters, panicle length, 1000-grain weight, kernel L/B ratio, length after cooking elongation ratio had positive highly s...

The current paper has presented the study results of second-generation hybrid population ‘Bakhus x Kontakt’ combination. variety ‘Bakhus’ is large-kernelled, vigorously growing, tall, unresistant to lodging, ‘Kontakt short, resistant medium-kernelled. purpose was analyze inheritance a number quantitative traits in F 2 rice and select best plants for further breeding process. In process hybridol...

lead to continuing effects for increasing extensive of yield by means of advanced agronomic operations and selection of high yielding resistant genotypes. there fore, due to evaluation and determination of best effective traits in improvement of yield and grain quality of local populations of winter wheat, an experiment was carried out in uremia agricultural research station, on 30 local popula...

Kernel weight is important for plant breeders to select high productive plants. The determination of relationships between kernel weight and some fruit-kernel characteristics may provide necessary information for plant breeders in selection programs. In the present study, the relationships between kernel weight (KW) and 7 fruit-kernel characteristics: Fruit Length, (FL,), Fruit Width (FW) Fruit...

Abstract Background and aims Pb Sn concentration increase rapidly due to the industrial revolution cause a significant reduction in wheat production productivity. Understanding genetic control of tolerance is very important produce cultivars that are tolerant such metals. Methods Extensive analyses using genome-wide association study, functional annotation, gene enrichment were investigated set...

in order to study the sowing system, row distance and weeding effect on yield and yield components of intercropped maize with peanut, this experiment was conducted, as factorial based on a rcbd with three replications at the research farm of agriculture center of zabol university (iran) during growing season 2011- 2012. sowing system were four levels including sole maize, sole peanut, 50% maize...
