Studies on morphological characters of gladiolus (Gladiolus grandiflorus) Cultivars under Allahabad agro climatic Condition

Abstract

The present experiment was conducted during October 2011 – April 2012 in the Department of Horticulture, Sam Higginbottom Institute of Agriculture Technology and Science, Allahabad, (U.P.). The experiment of design was randomized block design consisting 11 treatment with 3 replication, with a view to find out the overall performance of different cultivars of Gladiolus viz. Panjab Morning (T1), Green Bay (T2), Novalux blue (T3), American Beauty (T4), Priscilla (T5), White Prosperity (T6) Red Majesty (T7), Summer Shunshine (T8) Delhi local (T9), Novalux (T10), Candyman (T11). On the basis of different growth and yield parameters the maximum plant height (125.16 cm) were recorded by Red Majesty following by Candy man (T11) (124.56 cm). The maximum number of leaves (8.71) was recorded in American Beauty and maximum days taken for spike initiation (69.06 days) was observed in white prosperity. The minimum days taken for colour showing of; first floret (73.86 days) were recorded in white prosperity. The minimum days taken for complete opening of first floret (3.17 days) was Delhi local. An analysis of the maximum weight of spike (64.40 g) was observed in White Prosperity and the maximum number of spike/plant (17.73%) was recorded by Delhi Local’ which can be recommended for cultivation in Allahabad agro-climatic condition.
