Summary
Bazı çeltik genotiplerinin (Oryza sativa L.) verim ve kalite parametreleri arasındaki ilişki korelasyon analizi ile belirlenmiştir. Çalışma; Erbaa, Niksar, Pazar lokasyonlarında iki yıl 15 çeltik genotipiyle gerçekleştirilmiştir. Denemeler, Tesadüf Blokları Deneme Desenine göre dört tekerrürlü olarak kurulmuştur. Genotipler, Spearman korelasyon testine göre incelenmiştir. Çeltik verimi (PY) ile salkım çıkarma süresi (PHT, r = 0.163*), olgunlaşma süresi (MT, r = 0.252*), salkımda tane sayısı (NGP, r = 0.325**), bin tane ağırlığı (TGW, r = 0.159*), metrekarede salkım sayısı (TNPM, r = 0.282**), tek salkım verimi (SPY, r = 0.188*), kırıklı pirinç randımanı (BRY, r = 0.721**), kırıksız pirinç randımanı (UBRY, r = 0.502*), hasat indeksi (HI, r = 0.651**) aralarında önemli pozitif korelasyon belirlenmiştir. Kalite bakımından kırıklı (BRY) veya kırıksız (UBRY) pirinç randımanı ile salkımda tane sayısı (NGP, r = 0.768**), metrekarede salkım sayısı (TNPM, r = 0.629**), hasat indeksi (HI, sırasıyla; r = 0.729**, r = 0.503*) aralarında önemli pozitif korelasyon saptanmıştır. İncelenen özelliklerden elde edilen veriler, verim ve kalite bakımından üstün çeltik genotiplerin ıslah edilmesi sırasında ıslahçılara yardımcı olacaktır.

Abstract
The correlation between yield and quality parameters of some paddy genotypes (Oryza sativa L.) was determined by correlation analysis. The study; Erbaa, Niksar, Pazar locations were carried out with 15 paddy genotypes for two years. The experiments were established with four replications according to the Randomized Blocks Experimental Design. Genotypes were examined according to Spearman correlation test. Paddy yield (PY) and panicle heading time (PHT, r = 0.163 *), maturation time (MT, r = 0.252 *), the number of grains per panicle (NGP, r = 0.325**), thousand grain weight (TGW, r = 0.159 *), the number of productive tillers per square meter (TNPM, r = 0.282**), single panicle yield (SPY, r = 0.188 *), broken rice yield (BRY, r = 0.721 **), unbroken rice yield (UBRY, r = 0.502 *), harvest index (HI, r = 0.651 **) was a significant positive correlation between them. In terms of quality, there was significant positive correlation between broken (BRY) or unbroken (UBRY) rice yield and the number of grains per panicle (NGP, r = 0.768 **), the number of productive tillers per square meter (TNPM, r = 0.629 **), harvest index (HI, r = 0.729 **, r = 0.503 *, respectively). The data obtained from the investigated properties will help breeders in breeding superior paddy genotypes in yield and quality.
