تقييم أداء عدة تراكيب وراثية من الحبة الحلوة Foeniculum vulgare

Abstract EN

Fennel is considered as herbaceous crop belonging to apiaceae which used as spicy and medicinal plants.

Field test experiment was conducted out for two successive seasons of 2011/2012 and 2012/2013 using four genotypes of fennel to assess the nature and extend of variability of these genotypes via some agronomical traits.

Genotypes were randomly distributed underwith completely randomized block design with three replicates.

Analysis of variance showed highly significant differences among genotypes in all traits.

Where, genotype Amego was superior in average of branches per plant of 13.67 branch.plant-1 (for first season), umbellets per umbel of 29.00 and 51.00 umbellets.

Umbel-1, weight of umbel of 42.67 and 36.00 gm, diameter of umbel of 13.33 and 16.67 cm and plant height of 145.00 and 148.3 cm, for each season, respectively.

Whereas, Romanesco gave highest average of umbel of 22.00 and 23.67 umbel.plant-1 and branches no.

of 17.00 branch.

plant-1 (for second season).

Highest GCV and PCV were recorded for weight of umbel of 36.00 and 36.42 followed by plant height of 31.40 and 31.51 consequenced by number of branches of 30.82 and 31.17, in first season, for each coefficient, respectively.

In second season, highest GCV and PCV were registered in umbellets no.

of 52.83 and 53.16 followed by branches no.

of 45.00 and 45.30.

Furthermore, superior heritability was noticed in plant height of 99.18 consequenced by branch no.

of 97.74 and umbel weight of 97.73, for first season.

While in second season, the highest heritability was observed in umbellets no.

of 98.79 followed by branches no.

of 98.69 and plant height of 98.58.

These results could be used in genetic diversity to identify genotypes and plan a breeding programme to improve these genotypes.

Where, morphological selection could be effective to improve some traits of fennel.
