تقييم أداء بعض التراكيب الوراثية المدخلة لمحصول الشعير Hordeum vulgare تحت ظروف منطقة الجبل الأخضر-ليبيا

Abstract EN

A field experiment was carried out on the farm of the Crops Department, faculty of Agriculture, Omar al-Mukhtar University, during the 2021-2022 season, in order to evaluate the performance of some barley crop genotypes under rain-fed agriculture conditions in al-Jabal al-Akhdar-Libya, to create a genetic base and create variation, which helps provide varieties that are compatible with the conditions of the region.

genotypes Input from the Arab Center for Studies of Arid Zones and Dry Lands (ACSAD1852, ACSAD1825, ACSAD1863, ACSAD1859, ACSAD1816, ACSAD1861, ACSAD1772, ACSAD1829, ACSAD1818,).

a randomized complete block design (RCBD) was used to implement the experiment in three replications.

the results of the statistical analysis showed: significant differences between the genotypes, with the ACSD1825 genotype superior in number of grains/ spikes, weight of a thousand grains (g), grain yield (ton/ha) and harvest index (%).

While the ACSAD 1852 genotype was superior in terms of spike length (cm) and plant height (cm).

the ACSD 1863 genotype showed the highest values for spike weight (g) and straw yield (ton/ha).

the results also showed a significant superiority of the 1816 ACSD genotype for the biological yield (ton/ha).
