This research was conducted in order to determine the relationship between grain yield and yield components, using 30 common bean varieties in a randomized complete block design with four replications at the Agricultural filed faculty of Agriculture,Tehran university In this study 18 traits were assessed on 10 random plants from each plot. The result showed that there were significant differe...

Since cucumber is one of the most economically important horticultural crops, production of hybrid seeds is very important for obtaining a profitable fruit yield. Detecting the best combination of the parents is one of the most important stages in each breeding program. By selecting parents with high heterosis in their progenies, breeders will be able to generate hybrids with high yield. This s...

In order to evaluate the productivity of 20 bread wheat promising lines using multivariate statistical methods, an experiment was conducted based on a randomize complete block design under terminal moisture stress, in 2011-2012. Factor analysis showed that the three first factors explained 66% of total variance. Plant height, peduncle length, 1000 kernel weight, harvest index, biological yield,...

An imbalanced nutrients status in the nutrient solution, i.e. poor nutrition of the plant, is often responsible for the low quantity and quality of strawberry fruit. The present study was conducted to investigate the effect of different ratios of potassium to magnesium (K/Mg) (T1, 2:1, T2, 4:1, T3, 6:1 and T4, 8:1) on fruit yield and quality of strawberry cv. Albion under hydroponic conditions....

In order to investigate the diversity and relationship between agronomical traits with seed yield components in barley, twenty advanced barley lines were evaluated in a randomized complete block design with 3 replications at Research Center of Agriculture in Sistan in 2006. Each plot consisted of six rows spaced 20 cm apart and 5 meters long. In this research, 24 Agronomic traits were measured ...

To estimate the relationship between honey yield and some of the morphological characters, five queen-daughters from each of 30 queen-mothers were studied. The queen-mothers were selected randomly from the apiary of Research Center of Animal Science and Natural Resources in Isfahan Province. Summer honey yield was measured from the difference of honey comb before and after honey extraction whil...
