Genetic Variability for Seedling Traits in Wheat (Triticum aestivum L.) under Moisture Stress Conditions
M. Qayyum Khan, Saeeda Anwar and M. Ilyas Khan

Abstract: The investigation was mainly restricted to morphpogical response of four wheat genotypes to water deficit conditions. The seeds of four genotypes were sown in two wooden trays at normal laboratory conditions. These genotypes were evaluated for seedling traits under four moiture regimes viz. control tap water 100, 70, 50 and 30% tap water of control. Analysis of variances revealed significant differences in most of the seedling traits, indicating the notable genetic variability among wheat genotypes at different moisture levels. Significant genetic variability and heritability existed for all seedling and emegence traits. The estimates of genetic variances were smaller than their respective phenotypic variances for all the traits evaluated. The correlation of most of the seedling traits were positive and significant with each other. Root/shoot ratio and dry root weight show significant negative correlation. Non significant correlation was also observed in emergence rate index and root/shoot ratio. The estimates of coefficient of variability (CV %) indicated that the maximum variation for root/shoot ratio, emergence rate index, fresh shoot weight, dry shoot weight and fresh shoot length.
