Diyarbakır ekolojik koşullarında pamuğun (Gossypium hirsutum L.) bazı genotiplerinin verim ve lif kalite özelliklerinin araştırılması

ABSTRACT This study was carried out in randomized block design with 3 replications 9 cotton lines (Line 1-9) and 3 standard cotton varieties (ST468, BA119, and DP396) were used as material in Diyarbakır Central and Bismil ecological conditions in 2018. The study was carried out to investigate the genotype, location and property relations by examining some yield traits (single boll seed cotton weight, seed cotton yield, ginning rate, and 100 seed weight) and some fiber quality traits (fiber fineness, upper half mean lenght, fiber strength and spinning consistency index). When the examined features were evaluated separately, the differences between genotypes were found to be statistically significant, while the differences between locations were not significant. However, when all traits are examined as a whole, the differences between Bismil ecological location and Diyarbakır ecological location are high; Line1, Line2, Line3, Line7, Line9 and ST468 genotypes can be suggested to Diyarbakır Central ecological location and Line8 genotype will be suggested to be Bismil ecological location. Key Words: Yield, fiber quality traits, genotype and location, correlation, biplot analysis.
