ABSTRACT
The present study entitled, “Evaluation of hardwood and semi-hardwood cuttings for
rooting performance in exotic cultivars of kiwifruit (Actinidia spp.)” was carried out during
2019-2020 in the Department of Fruit Science, Dr. YS Parmar University of Horticulture
and Forestry at Nauni, Solan (HP). The experiment comprised of eight exotic cultivars as
treatment and the research trial was laid out according to Randomized Block Design (RBD).
The entire programme of study was conducted under two experiments with a view to
elucidate the comparative rooting performance of hardwood and semi-hardwood cuttings in
exotic cultivars of kiwifruit. Eight exotic cultivars namely; Anna, Chung Bai, Cordifolia,
Issai Kiwi, Kens Red, Meader Male, MSU Klur and 74-49 which were taken as treatment.
Each treatment was replicated thrice with 30 cuttings per cultivar. The cuttings for
experiment-Iwere taken in mid-January (hardwood cutting) and for experiment-II were taken
in mid-July (semi-hardwood cutting). Among different cultivars, Kens Red exhibited best
performance in term of root, shoot and leaf characteristics. The cultivar Anna performed least
on the basis of aforesaid parameters. The survival percentage after field transplanting was
also found highest in Kens Red cultivar, whereas, it was recorded minimum in Anna cultivar.
Among different cutting types, semi-hardwood cuttings of different cultivars performed
better as compared to hardwood cuttings with respect to parameters like per cent rooted
cutting, number of primary roots, number of secondary roots and the survival percentage.
However, hardwood cuttings performed better in respect of shoot and leaf characteristics. The
information generated on the propagation of these new exotic kiwiberry cultivars will serve
as a basis for theresearchers in developingnew rootstocks for quality production ofplants.
