Book Description
Wheat (Triticum aestivum) is king of cereals and it is the staple food of the people of Pakistan. To understand the genetics of drought tolerance two promising elite lines V- 04189 and V-03138 were crossed to develop F1, F2 and back cross generations (BC1 and BC2). Six generations (P1, P2, F1, F2, BC1 and BC2) were raised under water stress conditions. Analysis of variance showed significant difference among generation means which indicated presence of sufficient genetic variability. Hybrid vigor was observed in most of the cases except plant height, spike length and flag leaf area. Generation means analysis revealed presence of additive [d], dominance [h] and epistasis genetic effects in the inheritance of traits. Two parameter model [md] provided the best fit for spike length, number of tillers per plant relative water contents and excised leaf water loss which shows the presence of additive genetic effect is prominent with simple inheritance while, [ml] showed best fit for grain yield per plant that indicates epistasis is involved in the inheritance of trait. The remaining traits exhibited higher parameter models and indicating the complex inheritance.

Book Description
Emerging phenotyping methods and increasingly abundant genotyping platforms have become valuable tools for the discovery and introgression of yield-positive and stress-adaptive genes into modern wheat (Triticum aestivum L.). The main goal of this research was to identify genomic regions that contribute to yield potential and drought tolerance in wheat using agronomic and remotely sensed phenotyping approaches. Phenotypic interrelations, genetic variability of yield, yield components, phenology, and spectral reflectance indices (SRIs) were evaluated in a Pacific Northwest (PNW) winter wheat diversity panel (n = 402). The SRIs showed moderate to high phenotypic correlations with grain yield (|r| = 0.27 -- 0.84, p
