Title
Study on Correlation between Seed Yield and ITS Yield in Triticale Genotypes under Rain fed Conditions in Warm Areas
Authors
Abstract
Triticale has compatibility to a wide range of different climate conditions. This particular caused triticale to be introduced as an important crop among cereals. Accordingly, this research performed in Dry land Agricultural Research Station, of SHirvan (North Khorasan-Iran). 16 genotypes were compared in RCBD with three replications under rain fed conditions. Each plot had 6 rows 5-meter long. Observations were made on phonology, morphology and physiology traits during growth season and after harvesting. Variance analysis results indicated that there were significant differences at 1% probability level among genotypes for all studied traits. Genotype 9 had the highest seed yield (3776 Kg/ha) and the lowest number of days to maturity (212.3 days) and also indicated superiority to Check at 5% probability level. Seed yield correlation with No. of head in square meter, No. of seed in head, length of head was positive and significant at 1% probability level and to was negative and significant at 5% probability level with number of days to maturity. In general, No. of head in square meter and No. of seed in head can be introduced as selection indices under rain fed to profit high seed yield genotypes. Following this, genotype 9 can be advised for Shirvan and other areas with similar climate after determining its stability in stability experiments.
