Cultivation Experimentation of Walnut Early Fruiting Varieties at Central Yunnan Regions

The cultivation experimentation of 11 early fruiting walnut clones has been conducted in Kunming for 5 years, two clones coded 306 and 303 are selected as the suitable varieties for Kunming. These two varieties show the quality of desirable growth increment, vigorous branches, high ratio of both flowering and fruiting setting. The individual yield of 5 years old achieve 5.68 kg and 5.28 kg respectively, which are significantly higher than that of other clones. The comprehensive properties of 306 and 303 are also promising, with good size and shape, no emptied seed, and desirable oil content.
