Evaluation of some promising faba bean genotypes (vivia faba l.) in relation to broomrape (orobanche cernata) tolerance [electronic resource]

Includes bibliographic reference

This investigation was carried out at the two experiments at Sids Research Station, Beni -Suef Governorate during 2010/2011 and 2011/2012 growing seasons. Twenty faba bean (vicia/aba L.) genotypes were used included 14 ones promising Orobanche tolerant genotypes and 6 cultivars,Le., three tolerant and the three susceptible. Each experiment was included of three sowing dates 20th October, 5th November and 20th November in both seasons,was conducted in Orobanche infested field. Results showed that number and dry weight of Orobanche spikes were significantly affected by the sowing dates. The late sowing date on 20th of November reduced both number and dry weight of Orobanche as
5th compared with the two earlier sowing dates (20th October and November). The best results recorded for most faba bean characters were for sowing in 5th and 20th of November, respectively. They significantly increased seed yield (t/fed) over the sowing date in 20th October by , 103.9% and 63.6% respectively. The interaction between sowing dates and genotypes on Orobanche dry weight were significant in two growing seasons. Results indicated that there were significant differences between faba bean genotypes under Orobanche infestation field for each of the two growing seasons.
