Abstract

Many years studies showed that the main factors not being scale pecan production in the southern areas of the Changjiang River were later bearing age, low and unstable fruit yield. In 13 variatives of seedling progenies, about 0.3% of trees had high and stable production. The nut weight of progenies from seed or clone was light: and big fruit variaties exceeded parent trees were few. Seedling tree shoots top-working to big tree made juvenile stage short, with bearng fruit after 5 to 6 years. The kernel components of all variaties from seed had big difference, with 40.10% difference of oil content among trees. Dichogamy progenies were of 90.70%, and protandry was indominant position. The yield related to female flower, pollenizing conditions and climate at flowering season, not dichogamy.
