Interrelationships between seed yield and related traits in bread wheat genotypes in non-saline and saline environments
Journal Title: Scientific Journal of Crop Science - Year 2014, Vol 3, Issue 4
Abstract
Study of the interrelationships between yield and its components will improve the efficiency of breeding programs especially under saline conditions through appropriate selection criteria. The present research factor analysis was used to obtain more information on the relationship between various characteristics and profound understanding of data structures. Forty one genotypes of bread wheat were grown in two environments (non-saline and saline conditions) based on randomized complete block design with three replications. Electrical conductivity of irrigation water was 2 and 11 dS.m-1 in non-saline and saline environments, respectively. Results indicated that in non-saline environment selection based on the fourth factor including own length and biological yield efficiency have the highest community and high relative contribution in wheat seed yield. On the other hand, the results of factor analysis in the saline environment showed that the selection based on the first factor including biological yield, peduncle length, plant height and chlorophyll content will has the most effectiveness in the seed yield. Therefore, it seems that high yield of wheat plants under saline environments can be obtained by selecting breeding materials with high biological yield, peduncle length, plant height and chlorophyll content.
