Abstract:
A field experiment was conducted at Hi-tech Horticulture, Saidapur farm, Department of Horticulture, University of Agricultural Sciences, Dharwad during 2019-20 and2020-21 with a view to study the growth and yield of different rose genotypes. The experiment was laid out in Randomized Block Design with newly planted thirty seven rose genotypes, with two replications. The results of the experiment revealed that, the genotype (T₁₅) Lobo recorded maximum plant height (89.86 cm), plant spread in E-W (75.94 cm) and N-S (74.04 cm) direction, number of primary (7.10) and secondary (8.20) branches per plant, number of leaves per pant (148.75), stem girth (20.59 mm), yield parameter such asmaximum number of flowers per plant (46.60) and quality parameters like bud length at tight bud stage (5.36 cm). While maximum bud diameter at tight bud stage (3.78 cm) was found in the genotype (T₃₆) Gladiator. Whereas, minimum plant height (43.19 cm), plant spread in E-W (35.14 cm) and N-S (33.13 cm) direction, number of primary (3.78) and secondary (3.77) branches per plant, number of leaves per plant (38.75), stem girth (11.45 mm) and yield parameter viz., minimum number of flowers per plant (17.17) were noticed in the genotype (T₂₃) Confetti. However, the minimum bud length and bud diameter at tight bud stage was recorded in the genotype (T₃₅) Arka Sinchana (2.69 and 2.29 cm respectively).
