Bihar Agricultural University, Sabour

Bihar Agricultural University, Sabour established on 5th August, 2010 is a basic and strategic institution supporting more than 500 researchers and educationist towards imparting education at graduate and post graduate level, conducting basic, strategic, applied and adaptive research activities, ensuring effective transfer of technologies and capacity building of farmers and extension personnel. The university has 6 colleges (5 Agriculture and 1 Horticulture) and 12 research stations spread in 3 agro-ecological zones of Bihar. The University also has 21 KVKS established in 20 of the 25 districts falling under the jurisdiction of the University. The degree programmes of the university and its colleges have been accredited by ICAR in 2015-16. The university is also an ISO 9000:2008 certified organisation with International standard operating protocols for maintaining highest standards in teaching, research, extension and training.VisionThe Bihar Agricultural University was established with the objective of improving quality of life of people of state especially famers constituting more than two third of the population. Having set ultimate goal of benefitting society at large, the university intends to achieve it by imparting word-class need based agricultural education, research, extension and public service.

    Study of Genetic Diversity and Stability in Groundnut (Arachis hypogaea L.) Genotypes
    (Department of Plant Breeding and Genetics, BAU, Sabour, 2019-07-04) . Kumar, Sudhir; De, Nitish
    Groundnut (Arachis hypogaea L.) is an important oilseed crop globally. The present study was aimed at the phenotypic assessment of 51 groundnut genotypes and five control varieties for yield, oil and related traits under irrigated and post flowering drought stress conditions. These genotypes were evaluated under ten environments for seventeen traits. Experimental material was evaluated at two distinct locations, one at ICRISAT Patancheru, Hyderabad and at Bihar Agricultural University (BAU) Sabour. At ICRISAT the experiment were conducted during Kharif, 2015, Rabi 2015-16, Kharif 2016, Rabi 2016-17. At BAU Sabour the experiment was conducted during summer 2016. ICGV 13097, ICGV 13098 and ICGV 13100 showed higher pod yield per plot (kg/ha) with higher oil content and good buffering capacity. These genotypes for their specific performance can be utilized as cultivar for reference environments to harvest maximum pod yield with higher oil content. For nutritional quality traits like oleic acid content and O/L ratio, ICGV 13099, ICGV 13103, 13115, ICGV 13117, ICGV 15321, ICGV 15323, ICGV 15325, ICGV 15333 and ICGV 15339 had good buffering capacity with higher mean than population mean. These genotypes will be used for the quality oil production with international acceptance. In present investigation, there were heavy losses of pod yield in post flowering moisture stress conditions. Pooled mean yield (kg/ha) was higher in irrigated condition than rainfed condition and a loss of more than 29 per cent in stress conditions than in rainfed conditions for yield. ICGV 15314 had highest drought tolerance efficiency (DTE) with pod yield 2725 kg/ha in irrigated and 2242 kg/ha in rainfed conditions. Five best drought tolerant genotypes were ICGV 15314, ICGV 15321, ICGV 15325, ICGV 15331 and ICGV 15315. The higher yield level was due to higher number of branches/plant, higher number of pods per plant, pod yield per plant, 100 seed weight and shelling percentage and which are most important and key traits for stability of pod yield and these traits could be successfully employed for realization of higher productivity and ensures the possibility of predicting the performance of genotypes for higher productivity in groundnut.
