Analysis of Yield and Some Important Agronomic Traits of Iranian Triticale Genotypes in Farmer Conditions.

In this experiment seven promising lines of triticale (includes ET-85-4, ET-85-14, ET-85-15, ET-85-17, ET-84-17, ET-82-15 and ET-83-18) that showed their superiority during the past different experiment in Seed and Plant Improvement Institute, Karaj, Iran, were compared with Juanillo-92 as control in a randomized complete block design with three replications and two locations in South Khorasan province. Characteristics such as the number of days to heading, days to maturity, spike length, plant height, 1000-seed weight, peduncle length and grain yield were measured. Analysis of variance was conducted and compare with Duncan's test. The results showed that the genotype had a significant effect on the number of days to heading (1%), the number of days to maturity and spike length (5%) but no significant effect on other traits. ET-82-15 and ET-85-17, respectively, with means 12.48 and 12.43 cm had a highest spike length and ET-85- 14 had the lowest (11.30 cm). Although we had no significant differences in grain yield, but ET-83-18 had the highest yield with 6.29 tons/ha, which is 6.04 percent over its Juanillo-92 (5.91 tons/ha). ET-85-15 had lowest yield with 5.76 tons/ha. So that ET-83-18 is recommended in Birjand and similar areas and can be replaced by the Juanillo-92.
