原始语种摘要: ABSTRACT(#br)Knowledge on associations between yield and related traits is vital to improve selection efficiency in cultivar improvement. This study determined the relationships among qualitative and quantitative traits in bottle gourd landraces using simple correlation and path analyses. Results showed significant and positive correlations between the number of fruits per plant (NFPP) with number of male flowers (NMF), number of female flowers (NFF), plant height (PHT) and number of branches (NB). Number of seeds per fruit (NSPF) positively correlated with PHT, NMF, NFF, NB and fruit weight (FW). Fruit texture, degree of warts (DW), fruit shape (FS), and degree of neck bending, stem-end fruit shape and fruit neck length (FNL) had significant negative correlations with NFPP or NSPF. Path...
