Abstract
Wheat germplasm comprising commercial varieties, advanced genotypes, land races, intergeneric hybrids and some synthetic hexaploids obtained from CIMMYT were analyzed for variability of Fe and Zn in the seeds. Plants were grown under normal and saline plots having electrical conductivity of EC6-10 dS -m , soil pH between 7-7.6 and saturation percentage (SP) between 34.9 and 41.8. Seeds were digested according to AOAC official method of analysis. The digested samples in appropriate dilutions were analyzed using Atomic Absorption Spectrophotometer preset at wavelengths of 248.3 nm for Fe and 213.8 nm for Zn. Both the elements showed significant variation under control which ranges between 1.0-3.9 g/g dry seeds for Fe and between 1.5-3.5 g/g dry seeds for Zn. These values appeared significantly lower than the minimum (24 and 8 g/g dry seeds) and maximum (51-61 g/g dry seeds) values reported of Fe and Zn, respectively in wheat germplasm growing under normal soils. One of the reasons for low contents is the high pH of the soils in which the test material was grown. Salinity further reduced the values for both Fe and Zn (to 0.37-2.53 and 1.5-3.5 g/g dry seeds, respectively) reported for both chemicals. It is inferred that salinity not only reduces the productivity but the nutritional value of the cereals is also affected. It is therefore, imperative for breeding programmes on salinity tolerance to start with germplasm having a initial high range of both the essential elements in order to get quality cereals on saline lands.
