Abstract

The primary goals of Wheat Reach Program at Agricultural Research Centre are to develop cultivars of high yielding, shorten life duration, rusts resistant with good quality grains. Twelve early bread wheat lines were selected from 2009 through 2015 seasons from hybrid segregations using pedigree selection. The selected lines beside three checks (a total of 15 genotypes) were evaluated for their agronomic and grain quality under optimum and late sowing dates in north delta in 2015/16 and 2016/17 growing seasons. The grain yield and kernel weight elucidated significant decreases associated with late sowing in the two seasons and relatively affected by growing season as well as genotypic effects and genetic adaption. Under the optimum sowing date, the wheat genotypes recorded high values for days to maturity, plant height, grain yield, kernel weight, carbohydrates % and electrical conductivity in wheat grain leach and low values of crude protein, dry and wet gluten. The Lines 7, 6, 9 and 10 produced high grain yield under optimum and late sowing dates and could be reevaluated on the national level to confirm these results. Lines 7, 9 and 10 were the appropriate genotypes for delaying sowing date. Line 6 had high grain quality and could be used in breeding program to improve wheat grain quality.
