Abstract:
Studies on seed character of clone in loblolly seed orchard showed that there is great significant or mighty significant among clones in length and width of cone and weight of 1 000 seeds and full seed ratio and potential ability and efficiency of seed.There is abundant heredity and variance among clones.There is no significant within clones in length and width of cone and weight of 1 000 seeds and potential ability of seed.There is repeated ability within clones.The result showed that the seed character is strongly controled by heredity.There is significantce within clones in full seed ratio and efficiency of seed.The repeated ability is steady in length and width of cone and weight of 1 000 seeds and potential ability of seed etc.So it is possible to reselect seed orchard’s clone step by step based on characters of cone.
