Breed-specific identification tools are very much essential for better livestock management, to promote conservation and preservation of livestock genetic diversity. Microsatellites are markers of choice for breed characterisation and differentiation. This study is aimed to characterize and to identify breed-specific alleles in Madras Red and Mecheri sheep breeds by using FAO recommended microsatellite markers. DNA was isolated by a rapid, non-enzymatic method using non-ionic detergent from 50 unrelated animals of each breed. A total of 10 microsatellite markers are used for PCR amplification which is followed by polyacrylamide gel electrophoresis and silver staining. The silver-stained gels were analysed by Diversity Database software for sizing of various allelic products in both the breeds of sheep studied. Breed-specific alleles were observed in all loci in both the breeds, except Oar FCB 128 and TGLA 377 which showed breed-specific alleles only in Madras Red sheep. Such breed-specific alleles and their frequencies obtained in this study can be efficiently used to differentiate Madras Red and Mecheri sheep at DNA level.

Twenty-two accessions of different sources indigenously collected from India were planted in ICAR-Indian Institute of Oil palm Research Pedavegi during 2009 and evaluated for 2016-17, 2017-18 and 2018-19 and among the 257 palms, 20 pisifera, 109 Tenera and 128 Dura were identified. Among the pisifera palms two pisifera palms IC0610027-20 (TTD-1) is having 98.5 % sterility and IC0610024-47 (AND-24) is having parthenocarpic pisifera palm with 68.62 % fruit set. Average height increment of the palms per year was 39.03 and 50.67 cm, respectively.

The present study was conducted through FLD & OFT programmes at farmer field of Lakhimpur-Kheri district (U.P.) India. Banana bunches were sprayed twice first after full emergence of inflorescence (last hand) and second spray 15 days after first spray with GA3 @ 200 ppm on removal of male bud. The result of present study revealed that banana bunches GA3 @ 200 ppm found effective in reducing maturity days (approximately 13 days) and peal weight (38.7g).Pulp weight (119.7 g.),pulp/ peal ratio (3.13% ), finger weight (158.4g), bunch weight ( 29.45 kg.) and yield percentage (8056 %) were increases over untreated plot. It is also reported that on an average difference of gross cost spend Rs. 2020.00 /ha. may increases average differences of gross return Rs. 67680.00/ha. and differences of net return Rs. 65660.00/ ha. and it also affect C:B ratio (2.95) and input output ratio (3.93).

The study was conducted at Instructional cum Research Farm, Department of Genetics and Plant Breeding, College of Agriculture, Indira Gandhi Krishi Vishwavidyalaya, Raipur Chhattisgarh during Kharif 2010 and 2011 and Rabi 2010-11 and 2011-12 respectively, to evaluate the variability and the gca of parents and sca of hybrids and also to assess the magnitude of heterosis for various yield and related traits and to identify the maintainer and restorers for different CMS lines. Improving the restorability of swarna and dubraj variety using two approaches i.e. Isocytoplasmic (A x R) and Mutagenic approach was one of the objectives of the present study.
