Abstract

The Experiment was conducted at College of Horticulture, Bidar, UHS, Bagalkot. The growth of ornamental horticulture has been made possible by global trade, with Floribunda roses being the most economically significant. The ornamental business has seen a shift in the production and sale of flowers from the US and Europe alone to production in Africa and Latin America as a result of changes in global trade and an increase in energy costs. India is a rising leader in the export of roses to Europe. An idea of association can be effectively used to develop selection strategies for enhancing yield components from a research of varietal evaluation between various yield and biotic stress. The relative magnitude of the associations between various features and yield should be taken into account for any successful selection programme, therefore a comprehensive understanding of genotypes aids in determining the optimum genotype for a given area. Determining how several Floribunda rose types perform in terms of yield, economics, and biotic stress in the north-eastern transitional zone of Karnataka is the purpose of the current study. RBD was used to plan the experiment, which had 11 different types and three replications. The maximum flower output per plant and flower yield per hectare among the 11 types examined were documented by Cherishma, at 432.89 g and 4.01 t/ha, respectively. Five Star recorded the lower number of ashweevils (2.85), thrips (1.84), and variety Vanish recorded lower number of red spider mites (2.55). Cherishma had the highest gross returns and benefit cost ratio of all the types examined in the pooled mean (2,22,4,653 ha-1 and 2.56 respectively). However, a limited research work is done to know the performance of outdoor rose varieties. The cultivation of rose under open condition is gaining importance in Karnataka due to its relative ease in cultivation, high returns, increasing market demand and high communication facilities. So far, the research work done on the evaluation of rose cultivars to find out their suitability to this tract is meagre. Considering the importance and popularity of rose flowers both in domestic as well as International markets, it is important to study the performance of Floribunda roses varieties for their performance in North Eastern Transitional Zone of Karnataka.

Conclusion

From this study, it is evident that adopting Cherishma variety, given maximum flower yield per plant and flower yield per hectare 432.89 g and 4.01 t/ha is most profitable by giving higher gross returns of ` 2,22,4,653 ha-1 and higher BC ratio of 2.56 as compared to rest of the varieties. This was a significant step towards good agricultural practices to adopt the suitable variety for North Eastern Transitional Zone of Karnataka.
