Abstract: Studies were carried out with 417 seedlings, of 4 crossed combinations for analyzing inheritance characters of three economic characteristics. The results showed that the nut size, bur size and nut rate with the pattern of quantitative character and continuous variation genetic characters. The nut size and bur size had the same inheritance trend, the non-additive effect was great in inheritance of the two characteristic, with in the progeny, nut size and bur size were tended to smaller. There were large proportions of additive gene effect in nut rate inheritance, and the nut rate was trended to lager in progeny with additive action of non-additive gene effect.

Key words: Chestnut, Artificial cross, Characteristics inheritance, Heritability of crossed combinations
