مقایسه عملکرد و اجزای عملکرد چند ژنوتیپ پنبه در یک خاک شور

However as like the most plants, cotton is relatively salt tolerant, in terms of tolerance degree and seed cotton production in a given salinity, species and even different genotypes of cotton is not equal. Therefore, during years 2009 and 2010 in a field experiment, yield and yield components of 10 cotton genotypes were studied in a saline soil to determine preferable genotypes. Genotypes were including Sahel (as a commercial cultivar in area), Q28, 43200, Shirpan 539, Chucurova, Coker 312×349, Sepid, Sealand, Super okra and Opal. Based on the research results, the difference between boll weight and yield of cotton genotypes were significant, but yield earliness percentage did not have significantly difference. However, total yield of genotypes Coker 312 × 349, Sepid, 43200 and Shirpan 539 were did not have significantly difference compared to Chucurova, the later genotype produced the greatest total yield. While Genotype sealand produced the fewer yield than genotypes Sepid, 43200 and Shirpan 539, but difference between them was not significant. Yield difference of Sahel with other genotypes was not significant so that all genotypes were in the lowest group.
