Variation in Rooting Response of Shoot Cuttings in Twenty Clones of <I>Dalbergia sissoo</I> Roxb.

Abstract

The rooting behaviour is important for selecting clones for multiplication, as hard-toroot clones are likely to increase the cost of production of propagules substantially. In this experiment, rooting ability of nodal shoot cuttings of 20 clones of Dalbergia sissoo Roxb. were studied under intermittent mist conditions. Out of twenty clones, clone No. 33 (Tulsipur, Gonda), 24 (C.B. Ganj, Bareilley), 10 (Pathri, Haridwar), 237 (Banketwa, Gonda), and 9 (Chiryapur, Bijnor) produced the maximum shoot diameter, dry weight of root and shoot, number of roots and average root length of resultant plants. Propagules of these clones could be produced of plantable size in less than 121 days.
