تقدير الأداء و التوريث و الاستجابة للانتخاب لمدخلات من الشعير العاري بتأثير البيئة

Abstract EN

This experiment was conducted at Mosul University-college of Agriculture and Forestry during the seasons 2010-2011 and 2011-2012, Seven of naked barley entries introduced from ICARDA in addition to the locally grown variety Rihane-3 were grown under the rain fed conditions.

The characters studied were: number of days to 50 % flowering, maturity date, plant height, spike length, number of grains/ spike, number of tillers/ plant, number of spikes/ m2 , biological yield, grain yield, harvest index and 100-grain weight.

Highly significant differences between entries were found for : number of days to 50 % flowering, maturity date, number of grains/ spike, and grain yield/ plant.

The variance spike length was high for significant at 5%.

The result recoated highly significant difference were found for characters: number of days to 50 % flowering, maturity date, number of tillers/ plant, number of spikes/ m2 , number of grains / spike, and grain yield.

The interaction between entries and years were highly significant different for characters: number of days to 50 % flowering, maturity date, spike length, number of grains/ spike, grain yield/ plant.

While significant at 5 % for 100-grain weight.

Heritability values in broad-sense were high for characters grain yield/ plant.

The expected genetic advance in season 2010-2011high for: number of tillers/ plant, number of grains/ spike and medium for plant height, spike length, number of spikes / m2, grain yield harvest index and 100-grain weight.

Values of phenotypic and genetic coefficient variances were high for number of grains/ spike in 2010-2011 season .
