New records of water mites (Acari: Hydrachnidia) from the Uttarakhand State of India are presented. Four species, i.e. Torrenticola uttarakhandensis, T. chatterjeei (Torrenticolidae), Atractides indicus and Hygrobates dobriyali (Hygrobatidae) are described as new to science. The first description of the female and deutonymph of Sperchon indicus Kumar, Kumar & Pešić, 2007 is given. Atractides cf. incertus Lundblad, 1969 is reported as new for the fauna of India.

Data on performance records of 1249 Frieswal daughters of 71 sires over a period of 13 years from [2000][2001][2002][2003][2004][2005][2006][2007][2008][2009][2010][2011][2012] LL and CI were low (0.17 ± 0.10 and 0.11 ± 0.09

Six diverse brinjal lines were crossed in a diallel fashion (excluding reciprocals) to obtain fifteen cross combinations to study combining ability for important horticultural traits. Significant differences were observed among genotypes for all the traits studied. The parent Pusa Purple Cluster emerged as good general combiner for day to first flowering, days to 50% flowering, days to first harvesting, per cent fruit set and number of fruits plant-1. Whereas, the Arka Shirish was identified as good for plant height, plant stem girth, number of primary branches plant-1 , fruit length, fruit diameter and average fruit weight. Similarly Pant Samrat was good for number of flowers cluster-1 and yield plant-1. The highest specific combining ability effects in desirable direction were observed in cross Pusa Purple Cluster×Pant Samrat for days to first flowering, days to 50% flowering, days to first harvesting, plant height and per cent fruit set, Pusa Purple Cluster×Arka Shirish for plant stem girth, Pusa Purple Cluster×Arka Kusmakar for number of primary branches plant-1 , Arka Neelkanth×Arka Kusmakar for fruit length (cm), Arka Shirish×Arka Kusmakar for fruit diameter, Arka Neelkanth×Arka Kusmakar for average fruit weight, Arka Nidhi×Arka Shirish for number of flowers cluster-1 and cross Pusa Purple Cluster×Pant Samrat for number of fruits plant-1 and yield plant-1 .

Abastract:In the present study in vitro antimicrobial and antioxidant activities of Prunus persica family rosaceae were carried out from the bark extract of the plant. The methanolic extract was tested for their antimicrobial study against gram positive and gram negative bacteria and for their antioxidant activity using scavenging activity of DPPH (1,1 diphenyl-2-picrylhydrozyl) radical method. The plant extract showed remarkable antibacterial and antioxidant activity.

Hydrachnidia, commonly called water mites are an important and diverse group of benthic insects which is usually neglected by the aquatic biologists in their routine biodiversity duties. Present study is an attempt to investigate the dynamics and diversity of water mites from a freshwater stream Randi Gad from Pauri Garhwal which is a lower order stream of river Alaknanda. Mites were collected using a square framed Surber Sampler of 1m2 of the stream bed. Samples were preserved and brought to laboratory for further study. A total of fourteen species from five families were observed with a maximum density of 138 mites.m-2 in the month of January. Coefficient of similarity and Shannon wiener diversity index was calculated for diversity and cluster analytical study.
