Abstract:

In this study, it was aimed to determine the correlation between yield and quality parameters of some paddy genotypes (Oryza sativa L.) by correlation analysis. The research; Erbaa, Niksar, Pazar locations in 2016 and 2017 vegetation period was carried out using 15 paddy genotypes. 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.
