Pedigree selection was practiced on two bread wheat populations, namely i.e. (Debeira x Sahel 1) as considered population I and (Sids 6 x Sahel 1) as considered population II. Experiments were conducted under drought stress conditions (at 12 % soil moisture content) in order to improve yield and its component traits (no. of spikes / plant, biological yield, grain yield / plant and 1000-grain we...
JANMOHAMMADI MOHSEN, SABAGHNIA NASER, NOURAEIN MOJTABA. 2014. Path Analysis of Grain Yield and Yield Components and Some Agronomic Traits in Bread Wheat. Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 62(5): 945–952. Development of new bread wheat cultivars needs effi cient tools to monitor trait association in a breeding program. This investigation was aimed to charact...
To determine gene action and heritability of grain yield related traits in rice, six rice varieties including Hashemi, Vandana, Kadous, Hassani, Shahpasand and IR36 were crossed in a diallel design in 2010. The parents and seeds of F1 generation (36 genotypes) were grown in a completely randomized block design with three replications at the Research Field of the Rice Research Institute of Iran-...
Grain yield has a usually the low heritability, consequently to predict this trait it is recommended to use some morphological characters having a high heritability with high correlation with grain yield. To study of relationships between traits and to find out traits having the high influence on grain weight, 36 winter wheat cultivars were planted through a randomized complete block design wit...
1000-Grain weight and spikelet number per panicle are two important components for rice grain yield. In our previous study, eight quantitative trait loci (QTLs) conferring spikelet number per panicle and 1000-grain weight were mapped through sequencing-based genotyping of 150 rice recombinant inbred lines (RILs). In this study, we validated the effects of four QTLs from Nipponbare using chromos...
This study aimed at evaluating the effect of different planting dates (different ambient temperature conditions) on the characteristics of rice panicle and yield of its cultivars in Khuzestan climate in 2010. The experimental design was a split plot in a Randomized Block Design with four replications. The main factor was the planting date with three dates (May 25th , June 9th , and June 25th ) ...
in order to determine the best index for evaluating maize genotypes, 15 maize inbred lines were evaluated in two planting dates, 6 july to coincide heat stress with pollination time and 27 july as normal planting to avoid high temperature during pollination and grain filling period, using a randomized complete block design with three replications, in shushtar city, in 2007. result showed that i...
Three maize hybrids (Baber, Pioneer 30P45 and Syngenta 6621) were compared for yield and yield components and correlations were worked out among the yield parameters at various nitrogen levels in an experiment conducted at Agricultural University, Peshawar, Pakistan during summer 2009. The experiment was laid out in randomized complete blocks with split plot arrangement having three replication...
The aim of present study was to determine the relationship between grain yield and important agricultural characteristics for six lines of rice and Shiroodi cultivar as control in rice research station (Tonekabon) in west of Mazandaran Province in 2015. The experiment was conducted in a randomized complete block design with three replicates. Analysis of variance showed that there was a sig...
in order to investigate the contribution of ear photosynthesis and cytokinin in determining grain sink size, a pot study was conducted during january to june 2005 in cereal glasshouse of faculty of agriculture of karaj, iran. experiment was conducted in a complete randomized design with a factorial arrangement of two factors, three replications and four pots in each plot. factors included culti...
