| Abstract: | Cooksfoot(Dactylis glomerata) is an important forage grass and is widely cultivated in the world due to high forage yield,good quality,and stresses tolerance.The objectives of this study were to collect the necessary data on morphological and phonological traits in order to engage in genetic analysis and breeding program in cooksfoot materials with various chromosome ploidy levels.This study indicated that the growth period of tetraploid accessions was shorter than that of diploid accessions.Among 14 morpho... |
