Germplasm Enhancement for Water Stress Tolerance and Storage Insect Resistance in Bread Wheat (Triticum aestivum L.) (original) (raw)

Abstract

This study was carried out during three successive seasons 2004/05, 2005/06 and 2006/07, to evaluate fifty F derived lines (from the F diallel cross), with three check varieties under two different irrigation regimes. 3 2 Twenty different lines were selected from the fifty F lines under each level of irrigation and evaluated under 3 the same conditions in the F and F generations. Also, the effect of irrigation regime on insect infestation of 4 5 stored grains for six F selected lines under each level was studied. F results revealed that highly significant 5 3 differences were obtained between the two irrigation regimes for all traits studied. Highly significant differences among genotypes were obtained in normal (L) and water stress conditions (L) as well as in their combined 1 2 data for all traits studied except grain yield / plant in combined data only. F results revealed that highly 5 significant differences among F selected lines were found for all traits studied at the two irr...
