[Method] In 2011-2014, various biological traits of two new introduced cherry varieties and a local variety were evaluated and compared, including plant growth, characteristics of branches, leaves and flowers, fruit economic traits, phenological response, yield traits and stress resistance. [Result] Black Pearl and Pitch-Black-skinned Cherry exhibited better performance than the local variety, with the branch germination rate of 85.42% and 80.95%, branching rate of 18.75% and 15.87%, spring shoot length of 35.5 cm and 31.6 cm, annual spring shoot growth of 6 223.2 and 5 956.6 cm, leaf size of 14.9 cm × 7.6 cm and 13.8 cm × 8.1 cm, flower size of 2.5 cm ×2.6 cm and 2.3 cm × 2.4 cm, fruit ma- turity stage in late April-early May and early-mid May, average single fruit weight of 3.85 g and 3.68 g, sugar content in fruit juice of 14.5% and 14.2%, fruit edible rate of 76.47% and 77.23%, fruit-bearing rate of 28.48% and 29.81%, average yield per plant of 15.6 kg and 11.9 kg, converted output of 12 282 kg/hm2 and 9 814.5 kg/hm2, respectively. In addition, these two new introduced cherry varieties demonstrated strong adaptability and relatively strong adaptability, respectively. Therefore, Black Pearl exhibited the best performance, followed by Pitch-Black-skinned Cherry, which were both superior to the local variety. [Conclusion] Black Pearl can be selected as the main cultivar with supporting cultivation techniques in Northern Guizhou region, appropriately combined with Pitch-Black-skinned Cherry.展开更多
