Description Thesis-PhD
The present investigation was carried out at the Model Floriculture Centre, G.B. Pant University of Agriculture and Technology, Pantnagar, District Udham Singh Nagar (Uttarakhand) during 2007 to 2008. The experiment was laid out in a randomized block design with 12 varieties replicated thrice with thirty six plants per replication. Significant differences were recorded among the varieties for all the characters in both the years as well as in pooled data. The var. Shringar was earliest in spike emergence and took maximum days to lowest floret wither. It also yielded maximum number of spikes per plant and per square meter. The variety Hyderabad Single took minimum days to first floret opening and had maximum number of open florets per plant. The var. Vaibhav possessed maximum spike length and maximum open florets per spike. The var. Hyderabad double had maximum floret diameter and number of open florets per square meter. The maximum duration of flowering was attained in var. Double. The var. Swarna Rekha had maximum diameter of spike and maximum floret weight. The single petalled varieties Shringar, Prajwal and Kalyani Single were found to be superior from other varieties in concrete per cent, concrete yield per square meter and absolute per cent. The GC and GC-MS analysis of the compounds present in the absolute of these three single petalled varieties was done and it was found that there is a difference in the compound’s profile within same variety absolutely in two years of investigation.
