In order to evaluate of yield and yield components of cold tolerant chickpea germplasms, a trail was carried out based on incomplete block design with 81 chickpea germplasms and three replications in 12th Oct. 2006 at Mashhad Ferdowsi University, Agricultural Station. These germplasms had been selected among 700 accessions from RSPS (Research Center for Plant Sciences) Seed Bank after some cold tolerance studies in 10 years. Irrigation was done three times, immediately after sowing, 20 days after that and at flowering stage. Some characteristics including survival percent, yield components (pod numbers per plant, seed numbers per pod and 100 seed weight), seed yield, biological yield and harvest index were determined. Based on results, there were significant differences among germplasms
for all of the measured characteristics. Survival percent for 40% of germplasms was more than 76%. Also, seed yield for 16% of germplasms was more than 150 kg/ha. There were positive and significant correlations between seed yield and survival percent (r= 0.47**), pod numbers per plant (r=033**), seed numbers per pod (r=0.33**) and 100 seed weight (r=0.20**). Thus, it can be concluded that positive effects resulted from improving of morphological and phenological traits and yield components of germplasms in fall sowing , have resulted in yield enhancement. Regarding to 480 kg/ha as average chickpea yield in Iran, an increase to 2.5 times can be expected by fall sowing of cold tolerant chickpea varieties. |
