DUS Testing guidelines for cut flower orchids

The species of Paphiopedilum, are commonly called as 'Lady's or Venus's Slipper' orchids. The plants are characterized by their luxuriant and multicoloured flowers with shoe-shaped labellum or synsepalum, a structure unique to orchids that is formed by the fusion of two lateral sepals. The flowers have long vase life, and they remain on the plant m...

The experiment was laid out in a Completely Randomized Design (factorial) consisting of three cultivars and six calcium nitrate doses (0, 5, 10, 15, 20 and 25 g/m ² ). Among the cutivars, maximum bulblet multiplication was found in UHFS LA Lily Collection 1 (2.59) followed by Batistero (2.48) and Frans Hals (2.32), respectively. Among the different...

Marigold flower regulation by staggered planting dates

Studies were carried with an objective to identify the best date of planting to get optimum growth, flowering and seed production of snapdragon. The experiment was conducted for two years under mid-hill conditions of Himachal Pradesh. Planting was done at an interval of 15 day starting from September 17 in both the years with planting dates as; Sep...

This poster is about the salient achivements done in summer and rainy season annuals through selection, hybridisation, mutation and polyploidy breeding with their objectives.

The present investigation on effect of different black-out material(s) on off-season pot mum production of chrysanthemum (Dendranthema grandiflora Tzevelev) was carried out at the experimental farm of the Department of Floriculture and Landscape Architecture, Dr Y S Parmar University of Horticulture and Forestry, Nauni, Solan (H.P.) during 2011.

The effect of climatic conditions and planting dates on growth, flowering and seed production of candytuft (Iberis amara L.) under mid hill conditions of Himachal Pradesh during 2010-11 and 2011-12 were investigated. Six plantings were done at an interval of 15 days starting from September 17 in both the years with planting dates as; September 17,...

Ten cultivars of China aster [Callistephus chinensis (L.) Nees] were evaluated for 12 growth and flowering related traits to study their genetic parameters such as variability, heritability, genetic coefficient of variation (GCV), phenotypic coefficient of variation (PCV), correlation and path coefficient analysis. Significant differences among cul...

p>The studies on heterosis were carried with four male sterile lines namely; ms₇, ms₈, ms_9, ms₁₀ and 18 diverse pollinators as tester by using line × tester crossing programme. The 72 F₁ hybrids were produced and evaluated along with 22 parental lines during summer 2009 and rainy season 2009 in...

Studies on the effect of covering material on off-season cut flower production of chrysanthemum (Dendranthema grandiflora Tzvelev) were carried out at the experimental farm of the Department of Floriculture and Landscape Architecture, Dr Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh, during 2011 in na...

Satin flower (Godetia grandiflora Lindl.) belongs to family Onagraceae is usually grown as bedding plant for landscaping purposes and also as a cut flower. Earlier it was known as Clarkia amoena ssp. whitneyi. Satin flower is grown as a greenhouse cutflower in Japan and has received renewed interest as a field grown cutflower in California (Anderso...
