Investigation of Agricultural Characteristics in Some Lines Selected from the Kunduru-1149 Population

This study aimed to assess some of agricultural characteristics of some of pure lines selected from durum wheat landrace of Kunduru. 14 genotypes selected from the Kunduru population and durum wheat varieties of Zenith, Svevo and Fuatbey were tested in randomized complete block experimental design with 4 replications in Kahramanmaras conditions in 2011-2013 crop season. Results obtained from the research indicated that, except for the days to maturity and spike length, there were significant differences between genotypes for all traits under study. Heading period of genotypes varied from 129.5 to 138.1 days, flowering time from 133.3 to 142.8 days, heading-maturity time from 36.75 to 44.87 days, grain filling period from 32.00 to 41.00 days, days to maturity from174.3 to 175.8 days, plant height from 74.8 to 126.9 cm, spike length from 6.02 to 7.04 cm, stem length from 68.2 to 120.3 cm, peduncle length from 29.86 to 51.22 cm. Grain yield, on the other hand, varied between 357.5 and 538.4 kg da(-1). There were significant and positive correlations between grain yield vs. spike length, heading-maturity time vs. grain filling period. There were significant and negative correlations between grain yield vs. plant height, stem length, peduncle length, heading time, flowering time and days to maturity. The line of 14-12-9 (538.4 kg da(-1)) had the higher grain yield comparing Fuatbey, Svevo and Zenith and other genotypes. It was concluded that, for higher grain yield, the traits giving high correlations with this trait should be considered as selection criteria in wheat improvement programs.
