تقييم بعض صفات الإنتاجية لاثني عشر طرازا وراثيا من الذرة الرفيعة "Sorghum bicolor L. "تحت ظروف الإصابة بطفيل البودا (Striga hermonthica)‎ بمنطقة كندل-تشاد

الملخص EN

The study was conducted in two seasons (2017/2018 and 2018/2019) at Kundul area, Repuplic of Chad (L 11 ˚ 58΄ 35" N and E 15 ˚ 9΄ 00").

The study included twelve genotypes of sorghum, which varied in genetic traits obtained trom different sources: (S35, White dura, Red dura, ElSheta, Abo Deresha, Abo 45, Borzogly, Adaramata, Um Kora, Babashy, Asarika I and Asarika II).

The two genotype Asarika I and Asarika II entered from the White Agricultural Research Authority- Sudan, and the rest of the genotypes are of Chadian origins.

This study aimed to determination the best genotypes tolerated for parasite striga in terms of productivity.

Randomized compete block design (R.C.B.D) with three replicates were used in implementing the experiment.

The results of the experiment showed that the genotype Adaramata was significantly superior to the level of 5% in the two seasons adjectives: head weight 158 and 148 g.

and 100 grain weight (3.4 and 3.5 g.

Number and weight of grain per head (2124 and 2324 and 44.50 and 44 g and grain yield per Ha.

6.5 and 6.4tonn per Ha for the first and second season, respectively.

Asarika II was out standing in early flowering the two season respectively (54 and 55 days).

The study recommends using Adaramata, Asarika I and Asarika II genotypes in soil infected with Striga to get productivity
