Assam Agricultural University, Jorhat

Assam Agricultural University is the first institution of its kind in the whole of North-Eastern Region of India. The main goal of this institution is to produce globally competitive human resources in farm sectorand to carry out research in both conventional and frontier areas for production optimization as well as to disseminate the generated technologies as public good for benefitting the food growers/produces and traders involved in the sector while emphasizing on sustainability, equity and overall food security at household level. Genesis of AAU - The embryo of the agricultural research in the state of Assam was formed as early as 1897 with the establishment of the Upper Shillong Experimental Farm (now in Meghalaya) just after about a decade of creation of the agricultural department in 1882. However, the seeds of agricultural research in today’s Assam were sown in the dawn of the twentieth century with the establishment of two Rice Experimental Stations, one at Karimganj in Barak valley in 1913 and the other at Titabor in Brahmaputra valley in 1923. Subsequent to these research stations, a number of research stations were established to conduct research on important crops, more specifically, jute, pulses, oilseeds etc. The Assam Agricultural University was established on April 1, 1969 under The Assam Agricultural University Act, 1968’ with the mandate of imparting farm education, conduct research in agriculture and allied sciences and to effectively disseminate technologies so generated. Before establishment of the University, there were altogether 17 research schemes/projects in the state under the Department of Agriculture. By July 1973, all the research projects and 10 experimental farms were transferred by the Government of Assam to the AAU which already inherited the College of Agriculture and its farm at Barbheta, Jorhat and College of Veterinary Sciences at Khanapara, Guwahati. Subsequently, College of Community Science at Jorhat (1969), College of Fisheries at Raha (1988), Biswanath College of Agriculture at Biswanath Chariali (1988) and Lakhimpur College of Veterinary Science at Joyhing, North Lakhimpur (1988) were established. Presently, the University has three more colleges under its jurisdiction, viz., Sarat Chandra Singha College of Agriculture, Chapar, College of Horticulture, Nalbari & College of Sericulture, Titabar. Similarly, few more regional research stations at Shillongani, Diphu, Gossaigaon, Lakhimpur; and commodity research stations at Kahikuchi, Buralikson, Tinsukia, Kharua, Burnihat and Mandira were added to generate location and crop specific agricultural production packages.

    POLYMORPHISM OF PROLACTIN (PRL) AND PROLACTIN RECEPTOR (PRLR) GENES IN INDIGENOUS DUCKS OF ASSAM
    (Assam Agricultural University, Khanapara,Guwahati, 2017-07) BASUMATARY, KELESON; Das, Bula
    The present study was conducted to investigate the polymorphism of Prolactin (PRL) and Prolactin receptor (PRLR) genes in 101 indigenous ducks of Assam. PCR-RFLP analysis of PRL gene using restriction enzyme DraI revealed three genotypes, arbitrarily designated as AA, AB and BB. Following digestion, the AA genotype yielded two fragments (141 and 316 bp), the AB genotype yielded three fragments (141, 316 and 457 bp), and the BB genotype yielded one fragment (457 bp). The frequencies of A and B alleles were found to be 0.847 and 0.154 respectively and the genotype frequencies for AA, AB and BB genotypes were found to be 0.812, 0.069 and 0.119, respectively. The PCR-RFLP analysis of PRLR gene using restriction enzyme PciI revealed two genotypes, arbitrarily designated as AA and AB. The AA genotype yielded two fragments (108 and 259 bp) and the AB genotype yielded three fragments (108, 259 and 367 bp). The frequencies of A and B alleles were found to be 0.956 and 0.045, respectively and the genotype frequencies for AA and AB genotypes were found to be 0.911 and 0.089, respectively. On the basis of the present study, it was found that the A variant of PRL gene was predominant in the indigenous ducks of Assam with the highest frequency of AA genotype followed by BB genotype (AA>BB>AB). For PRLR gene, the frequency of allele A was higher than that of allele B with a higher frequency of AA genotype (AA>AB). Chi-square (χ2) test revealed that the population under study was not in Hardy-Weinberg Equilibrium for PRL gene, while for PRLR gene, the population was in Hardy-Weinberg equilibrium.
