Abstract: Propagability studies of three different clonal rootstocks (Myrocal (P. cerasifera), Julior (St. Julien x Pershore) and Jaspi (Methley x P. spinosa)) of Prunus species were undertaken in the Departmental field of Fruit Breeding at Dr. YSP UHF, Nauni-Solan (Himachal Pradesh). The experimental plant material was introduced from France and planted in the experimental farms. Hardwood cuttings, softwood cuttings and stooling methods were employed and the cuttings were treated with different concentrations of IBA. Observations recorded on different parameters reveals that with hardwood cuttings, among rootstocks, maximum sprouting (38.92%), rooting (26.75%), root length (27.17 cm) and number of roots per cutting (8.13) was obtained in Myrocal followed by Jaspi and Julior whereas among treatments maximum sprouting (31.30%), rooting (20.52%), root length (27.89 cm) and number of roots per cutting (8.30) was obtained with 5000 ppm IBA followed by 7500 ppm IBA for sprouting and rooting and 2500 ppm IBA for root length and number of roots per cuttings. Jaspi registered maximum sprouting (16.22%) and rooting (11.48%) whereas Myrocal registered maximum root length (16.04 cm) and number of roots per cutting (7.07) with softwood cuttings. In Myrocal and Julior very little rooting in cuttings treated with IBA was obtained while no rooting was observed in all the three rootstocks under study with control through softwood cuttings. Maximum rooted suckers (91.23%), number of roots per stool (17.20) and root length (29.99 cm) was observed in Myrocal treated with 2000 ppm IBA. Amongst all the rootstocks under study overall relatively higher success through hardwood cuttings and stooling was observed in Myrocal followed by Jaspi and Julior.
