Abstract:
Objective To select superior plant and clone of Dalbergia sissoo.
Method The height and diameter at breast height (DBH) of mother plants of four introduced D. sissoo provenances were measured. Twenty trees were selected as superior plants; The clone seedlings were propagated by grafting, then the height and DBH were measured to find superior clones for selective breeding of good varieties for D. sissoo with comparative analysis height and DBH among the 20 clones.
Result The height and DBH variable coefficient (VC) of mother plants of four D. sissoo provenances were very great, and both the height and DBH of the twenty selected superior plants were approximately equal to, or greater than 130% of the mean height and DBH of mother plants. The height and DBH of clone 9 and clone 10 were significantly greater than that of the other clones and the control, followed by clones 12, 19 and 20. The trunk was straight, and the DBH was large for superior plants 9 and 10, and the height and DBH of clones 9 and 10 were also 70% higher than the mean values of mother trees. The height and DBH of clones 9 and 10 were significantly higher than that of the other clones, and both 30% higher than the control. It is proved that clones 9 and 10 could be selected as superior clone.
Conclusion Twenty superior plants were selected, and twenty clones were reproduced, and clones 9 and 10 were chosen as the superior clones for selective breeding of D. sissoo.
