The results showed that the tested variety 10-2 exhibited the highest average yield of 61 520.9 kg/hm2, which was higher than Mantian 2180 as control by 33.7%. Varieties 10-2 and 10-3 showed the advantages of good fruit type, uniform size, thick pericarp, good hardness, high fruit setting rate, strong disease resistance, good low temperature resistance, good tolerance to stor-age and transportation and good quality. They could be planted for demonstration as export varieties in open field and greenhouse in mountainous area in Ningxia.展开更多
