this study was conducted to evaluate traits that have an effect on yield, and genetic variation for these traits, including dry matter accumulation, remobilization, and traits associated with them, in 10 grain sorghum genotypes obtained from the national plant gene bank of iran under moisture stress conditions. field trials were carried out in the 2008 cropping season using split-plot arrangeme...
Abstract Background Cotton ( Gossypium hirsutum L.) is grown for fiber and oil purposes in tropical sub-tropical areas of the world. Pakistan 4th largest producer cotton. It has a significant contribution GDP Pakistan. Therefore, present study was performed to assess genetic variations diversity yield quality traits cotton analyze associations among them. Results Analysis variance exhibited var...
One of the plant breeding strategies for increasing zinc content of wheat grain is employing natural genetic variability of this trait. To investigate genetic variation of traits related to zinc efficiency among Iranian spring wheat cultivars and determining the relationship between these traits and grain yield and its components, two separate experiments were conducted based on randomized comp...
Rice yield potential was greatly improved since the green revolution, but the occurrence of lodging often restricts the achievement of potential yield. Currently, it is still obscure about how the lodging-related traits change along with the genetic improvement in yield potential of rice, although much efforts have been devoted to study the trend of and physiological mechanisms underlying chang...
In order to study mode of gene action in rice for the traits related to yield, four varieties of rice were investigated. Direct and reciprocal crosses have been done between parents Sang-Tarrom and Gerdeh, IR229 and IRRI2 and their back crosses. The F1 and BC seeds were grown in 2006 and F1 plants were selfed for obtaining F2 seeds. Therefore, 10 different populations (generations) including ...
This research was conducted to study relationships among yield and yield components in Orchard grass (Dactylis glomerata). For this purpose 25 half sib families derived from poly cross of 25 parental genotypes were evaluated under two moisture environments (normal and drought conditions) according to a randomized complete block design at the research farm of Isfahan University of Technology. Th...
