Generation mean analysis to estimate genetic parameters for morphological traits in common bean (Phaseolus vulgaris L.)
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2014, Vol 4, Issue 4
Abstract
Six generation (P1, P2, F1, F2, BC1 and BC2) derived from two crosses ((A.1007 × DER.) and (GOLI × D81)) of common bean were grown in a randomized complete block design with three replication in 2010 at research field of Razi University, Kermanshah, Iran. Experiment was executed to estimate different genetic effects of five morphological traits (plant height, node number of main stem, node number of lateral branches, internode length and internode diameter) in common bean by using generation mean analysis. Results of analysis of variance showed that there was a genetic variation for traits. The results of generation mean analysis with three-parameter genetic model and also scaling tests (A, B, C and D) revealed inadequacy of the additive-dominance simple model to demonstrate the genetic mechanism controlling the traits. Hayman six parameters genetic model showed that dominance and epistasis effects were important in the inheritance of plant height, node number of main stem and node number of lateral branches, wheras only epistasis effect was important for internode length and internode diameter inheritance. Dominance effect had a more pronounced effect in genetic control of all characters. Furthermore, results of the study demonstrated existence of duplicate type of epistasis for most traits. Broadsense heritability estimates were greater than narrow-sense heritability for all traits in both crosses. The genetic advance estimates were low for all the traits except for plant height in GOLI×D81083 cross.

Impact of wastewater irrigation on concentration and absorption of nutrients and heavy metals in barley in calcareous soils
In arid and semiarid regions such as Iran, wastewater reuse can be a means to compensate for the lack of water. The use of refined wastewater in agriculture will reduce the use of agriculture water that it can be used f...
