Abstract

Agronomic evaluation of hybrids in early generations is essential for identifying promising genotypes with desirable traits such as early maturity, high yield potential, and superior adaptability to environmental conditions. This study focused on assessing key growth parameters, including plant height, branching pattern, plant spread, flowering behavior, and yield attributes. The evaluation was conducted at the Floriculture Unit, Department of Horticulture, University of Agricultural Sciences (UAS), Bengaluru, using a Randomized Complete Block Design (RCBD) with 11 treatments and 3 replications. The analysis of growth parameters at different developmental stages revealed significant variations among the hybrids. H1 (Arka Poornima × P.G. Purple) consistently exhibited the tallest plant height across all stages, while H3 (P.G. Pink × A.A.C – 1) produced more branches at early growth stages. H4 (Arka Poornima × A.A.C – 1) demonstrated strong vegetative vigor, with the widest plant spread and the highest number of branches at later stages. Additionally, H5 (P.G. Pink × P.G. Purple) showed notable plant spread in the North-South direction at 60 DAT. Regarding yield potential, H4 emerged as the most promising hybrid for maximizing flower production, while H6 also showed strong productivity. For seed yield, hybrids H7 and H3 exhibited superior performance, whereas early-maturing hybrids like H10, H2, and H4 could be advantageous for shorter cropping cycles and improved production efficiency. These findings underscore the potential of different hybrids for enhancing productivity and adaptability in diverse growing conditions.
