English Abstract

A field trial conducted at the Experimental Station of the Field Crops Sciences-Department-College of Agriculture, University of Baghdad, during 2010 to study the effect of mutagen nitrous acid, Gibberellic acid, Scarification and soaking in water on seed yield, yield components and quality of three Faba bean varieties(Zaina, Aguadulce and Local).

To find out the effect of these factors in different morphological traits, yield and its components and protein yield and how they respond to the genotypes of these factors.

Factorial experiment was used according to randomized complete block design RCBD with three replicates to each treatment.

The results of statistical analysis showed significant differences among treatments as followes: -Soaking seeds in mutagen nitrous acid for 24 hours gave a significant increases in most of the growth characteristics for all genotypes such as plant height 101.06cm, number of branches/ plant 12.40, leaf area index 3.1856 , number of pods/plant 29.66, seed weight rate 1.5144(g), seed yield 6629 (kg/ha), biological yield 10656 (kg/ha) and thus increased the harvest index 62.15% as well as increased protein yield 1362.7 (kg/ha) compared with other treatments.

-The highest average number of seeds/ pod was 4.456 and 4.489 when seeds soaked in Gibberellic acid at 100,50 ppm, respectively.

-Faba bean plants flowered early as scarification seeds was 79.33 day.

While soak the seeds in water for 24 hours gave the highest germination percentage was 94.44%.

There was no significant differences in seeds protein percentage among treatments.

II -Local genotype was superior to other genotypes in germination percentage 92.70%, plant height 88.23cm, leaf area index 2.4519, number of branches and pod/ plant 9.23, 26.44,respectively.

number of seeds/ pod 4.043, seed yield 5196(kg/ha)and harvest index59.78%, also gave the highest rate of the protein yield 1094.9(kg/ha) for Aguadulce and Zaina genotypes by its superiority in the protein percentage 21.71for Zaina genotype , as well as, excellence in seed yield 5196 (kg/ha) for Aguadulce genotype.

-Significant differences also observed for the interactions between genotypes and treatments in most of the studied traits, (Zaina XT1) gave the highest interaction of leaf area index, while (Local X T1) gave the highest interaction of seed yield and protein yield
