Screening of chickpea (cicer arietinum l.) genotypes for earliness, yield, yield components and resistance against fusarium wilt

Twelve chickpea ( Cicer arietinum L.) genotypes were evaluated for earliness, yield, yield components and resistance against fusarium wilt under field and laboratory conditions through two successive seasons; 2009/2010 and 2010/2011.  Under field conditions, generally for both seasons, L 138 had the first grade in case of number of days for flowering (earliness), number of days for maturity, seed weight / plant (g), 100 seed weight (g) and seed yield / feddan (ardab).  Also, the four Egyptian genotypes (Giza 88, Giza 1 and 2 and L 138) had better values than the eight ICARDA genotypes for the parameters mentioned before.  At the first season the least total fusarium wilt for both seedling and podding stages were noticed in case of L 138 followed by G88 and F 97 – 195 C with averages of 11.52, 12.78 and 15.65%, respectively.  At the second season it was the least with L 138 followed by F 97 – 195 C, G 88 and F 98 – 58 C with averages of 8.36, 9.55, 11.88 and 12.80%, respectively.  Under laboratory conditions, chickpea genotypes leaf extracts (CLE) decreased Fusarium oxysporum f.sp < em>. ciceris linear growth than chickpea genotypes root extracts ( CRE ) with averages of 3.79 and 5.88 cm., respectively.  The least linear growth in case of (CLE) cleared with L 138 and F 97 – 195 C with averages of 2.05 and 2.53 cm., respectively but F 98 – 58 C had the highest value with an average of 4.84 cm.  Using CRE, also L 138 and F 97 – 195 C had the best effect in reducing the fungal linear growth with averages of 2.86 and 3.62 cm. respectively.
