A comparison of efficiency parameters of SSR markers and genetic diversity analysis in Amorphophallus paeoniifolius (Dennst.) Nicolson BABT
Mandal,Rupsanatan; Nag,Sumita; Tarafdar,Jayanta; Mitra,Surajit.
ABSTRACT Amorphophallus (elephant foot yam) is an herbaceous edible aroid crop which belongs to the family Araceae. The study was undertaken to identify the efficient SSR primer that could differentiate a set of 12 elephant foot yam genotypes. Various efficiency parameters, namely, Polymorphism Information Content (PIC), Marker Index (MI), Resolving Power (RP) and Diversity Index (DI) were studied for 11 primers. The relationship between the parameters was studied using Spearman rank correlation coefficient. Discrimination analysis was done to find out the most effective parameter. Finally Principal Coordinate Analysis (PCoA) and dendrogram was done to find out the genetic diversity among the germplasm. The SSR markers under this investigation will...

Pal,Suprakash; Mandal,Rupsanatan; Sarkar,Indrajit; Ghimiray,Tulsi Saran; Sharma,Binay Raj; Roy,Ayon; Roy,Suvendu Kumar; Chakraboorty,Gautam; Mitra,Sabyasachi.
ABSTRACT The species richness and relative abundances of different aboveground plant-dwelling pest and predator species were assessed in flax (Linum usitatissimum L.) ecosystem under mid-hill conditions of eastern Himalayas. The experiment was conducted in winter seasons during 2004-2013 at the Regional Research Station (Hill Zone), Uttar Banga Krishi Viswavidyalaya, Kalimpong, West Bengal, India. Twenty five species of phytophagous arthropods under 13 families were observed belonging to 6 different orders. The gram pod borer, Helicoverpa armigera (Noctuidae: Lepidoptera), aphid, Myzus persicae (Aphididae: Hemiptera), shield bug, Plautia fimbriata (Pentatomidae: Hemiptera) and leaf webber, Nacoleia sp. (Pyralidae: Lepidoptera) were found as the most common...
