Yield changes and wheat remarkable traits influenced by salinity stress in recombinant inbred lines
Journal Title: International Journal of Farming and Allied Sciences - Year 2014, Vol 3, Issue 2
Abstract
More than six percent of areas in the world, or about fifty percent of the land area of wet land face with salinity problems. In Iran, saline soils area is over 18.5 million hectare. Since water resources with good quality irrigation products for the world are limited, the use of saline waters and lips passion for agriculture is inevitable in such circumstances, one of the factors of production and utilization of soil, water, saline tolerant crop varieties of salt. In order that changes yield and plant characteristics influenced by salinity stress in wheat recombinant inbred lines, a population of 278 RILs (F8 Recombinant Inbred Lines) of bread wheat derived from a cross of Attila/Kauz (salt sensitive) and Karchia (salt tolerant) were evaluated in α-Lattice Design with two replications under two environmental conditions (normal: water and soil salinity = 2 ds.m-1 & salinity stress: water salinity=11-17 ds.m-1 and soil salinity=13 ds.m-1) in Yazd in 2008, to determine the effect of salinity on grain yield and other characteristics. Analysis of variance showed that there were significant differences among varieties for concerned characteristics, indicating the existence of genetic variation among RILs. Salinity reduced the mean of characteristics, particularly, grain yield and grain weight.spike-1. The genotype × environment interactions were highly significant on grain yield and grain weight.spike-1, spike weight and some other characteristics, indicating that RILs responded differently to salinity condition for these characteristics. In contrast the genotype × environment interactions on plant height, peduncle length, spike length and grain no.spike-1 was not significant, indicating a lower differential response to salinity. For these characteristics, Biomass and harvest index had the highest correlation with grain yield in normal and salinity stress conditions.
