Drought is a disaster around the world accumulating salt and ero-sion in lands. Presently, a research was conducted to determine the morpho-physiological response in bread wheat under normal and stress irrigations. This experiment was conducted at the experimental field of Sindh Agriculture University, Tandojam, Hy-derabad, Pakistan, for two consecutive years during the Rabi season of the year 2011-12 and 2012-13. Stress was imposed by withhold-ing irrigations at three different growth stages of the plant, i.e. T1: normal irrigations applied, T2: stress at tillering stage, and T3: stress at the booting stage. The progenies Sarsabz x Khirman and Sarsabz x TD-1 contributed the highest heritability% (81.0% and 85.5%) for osmotic potential (-MPa) at stress at booting stage. For grain yield spike-1(g), the progeny Kiran-95 x Khirman showed maximum her-itability as 84.37 in T3. However, the progeny TD-1 x Imdad proved to be the best combiner progeny indicating highest heritability per-centage (91.0%) among the progenies for grain yield at booting stress.

Leaf and spikelet initiation of wheat (Triticum aestivum L.) was studied on plants grown in cabinets under a range of constant photoperiod regimes and on plants transferred, at different growth stages, between these regimes. The existence of genotypically specific limits to the effects of short photoperiods on the delay in floral initiation and on the increase in the number of spikelets was demonstrated. A long photoperiod applied after the onset of apex elongation, but not earlier, induced the differentiation of spikelets in the axils of already existing primordia, which under a short photoperiod would have developed into leaves. The initiation of the terminal spikelet was induced by a long photoperiod applied not later than the double ridge stage. The final number of spikelets had been determined by the time of swelling of the spikelet primordia in the central portion of the spike.
