Agriculture University, Jodhpur

Agriculture University, Jodhpur was established on 14th September, 2013 by Government of Rajasthan under Agriculture University, Jodhpur Act 21 of 2013 to focus on holistic development of arid and semi-arid regions of the state covering 6 districts (Jodhpur, Barmer, Nagaur, Pali, Jalore and Sirohi), constituting 28% of total geographical area which is sustaining 20.8% human and 28.4% animal population of the state. The districts under jurisdiction of the university cover 3 agro-ecological zones of the state. These are Arid Western Plain Zone Ia (Jodhpur and Barmer districts), Transitional plain of Luni Basin Zone IIb (Jalore, Pali, and Sirohi districts) and part of Transitional Plain of Inland Drainage Zone IIa (Nagaur district). The university has 1 institute of diploma and 3 colleges to produce highly competent educated human resources in agriculture and allied sciences besides 2 agricultural research stations, one each in zone Ia & IIb and 3 agricultural research sub stations, one in each zone to prepare, plan and perform highly need based research in this acute water scarce but naturally rich bio-diversified zone of the country. The third most important part in tri-pillar (Teaching, Research & Extension) of agricultural development, the extension for transfer of technologies are reached to doorsteps of the farming community by 6 Krishi Vigyan Kendras (K-V-Ks), 2 in Nagaur district and 1 each in Jodhpur, Barmer, Jalore & Sirohi districts under the umbrella of the university. The different units of teaching, research and extension are coordinating to systematically run by the headquarter situated at Mandor, Jodhpur.

    Genetic Variability, Correlation and Path Analysis in Sesame (Sesamum indicum L.)

    An experiment entitled “Genetic Variability, Correlation and Path Analysis in sesame (Sesamum indicum L.)” was carried out during kharif 2018-19 at the Research Farm of Agricultural Research Station, Mandor, Jodhpur (Rajasthan). The experiment was laid out using Randomized Block Design with forty genotypes in three replications to estimate the extent of genetic variability, heritability, genetic advance, correlation between yield and other characters and the direct and indirect effect of yield contributing traits through path coefficient analysis. Analysis of variance exhibited significant difference for all the characters suggesting the presence of great genetic variations among the genotypes studied. The phenotypic coefficient of variation (PCV) was slightly higher than the respective genotypic coefficient of variation (GCV) for all the characters, indicating less environmental influence on the genotypes. The highest magnitudes of PCV and GCV were observed for number of primary branches per plant whereas, the lowest was for days to maturity. Days to 50% flowering, days to maturity, number of primary branches per plant and seed yield per plant showed high estimates of heritability. High heritability coupled with high genetic advance as per cent of mean were altogether at a glance, observed for the traits like number of primary branches per plant and seed yield per plant suggesting additive gene action for expression of these characters. Hence, these characters may be proved as effective criteria for selection to improve seed yield in sesame. Correlation studies among the characters revealed that seed yield per plant had a highly positive and significant association with characters viz., number of primary branches per plant, number of capsules per plant, capsule bearing length and harvest index both at phenotypic and genotypic levels, therefore, selection for these characters may bring simultaneous improvement in the seed yield. Path coefficient analysis revealed that the highest positive direct effect on seed yield per plant exhibited by number of capsules per plant followed by capsule bearing length, harvest index, number of primary branches per plant, 1000 seed weight, plant height and days to 50% flowering, therefore, these traits may be used for further improvement in seed yield of sesame. Out of 40 genotypes EC-370867, IC-203936, RMT-251, IC-204531, RMT 244 and IC-203983 were found promising in seed yield and other characters. Hence, these genotypes would be used as parental source for future breeding programme.
