Acharya N G Ranga Agricultural University, Guntur

The Andhra Pradesh Agricultural University (APAU) was established on 12th June 1964 at Hyderabad. The University was formally inaugurated on 20th March 1965 by Late Shri. Lal Bahadur Shastri, the then Hon`ble Prime Minister of India. Another significant milestone was the inauguration of the building programme of the university by Late Smt. Indira Gandhi,the then Hon`ble Prime Minister of India on 23rd June 1966. The University was renamed as Acharya N. G. Ranga Agricultural University on 7th November 1996 in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga, who rendered remarkable selfless service for the cause of farmers and is regarded as an outstanding educationist, kisan leader and freedom fighter. HISTORICAL MILESTONE Acharya N. G. Ranga Agricultural University (ANGRAU) was established under the name of Andhra Pradesh Agricultural University (APAU) on the 12th of June 1964 through the APAU Act 1963. Later, it was renamed as Acharya N. G. Ranga Agricultural University on the 7th of November, 1996 in honour and memory of the noted Parliamentarian and Kisan Leader, Acharya N. G. Ranga. At the verge of completion of Golden Jubilee Year of the ANGRAU, it has given birth to a new State Agricultural University namely Prof. Jayashankar Telangana State Agricultural University with the bifurcation of the state of Andhra Pradesh as per the Andhra Pradesh Reorganization Act 2014. The ANGRAU at LAM, Guntur is serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication.

    EVALUATION OF BLACKGRAM (Vigna mungo) GENOTYPES FOR HEAT TOLERANCE AND HIGH YIELD
    (Acharya N.G. Ranga Agricultural University, Guntur, 2021-11-22) HARITHA., C; SANDHYA RANI, Dr. P.
    The experiment entitled "Evaluation of blackgram (Vigna mungo) genotypes for heat tolerance and high yield" was carried out in Crop Physiology Laboratory (Lab study) and in wetland farm (Field study), S.V. Agricultural College, Tirupati. Fifty blackgram genotypes obtained from Regional Agricultural Research Station, Lam, Guntur and Regional Agricultural Research Station, Tirupati were screened for heat tolerance using the standardized Temperature Induction Response (TIR) protocol, where seedlings were exposed to gradual and lethal temperatures in growth chamber. Among the 50 genotypes, top nine genotypes viz., LBG 977, PU 1504, LBG 982, LBG 971, ABF 04, LBG 973, NRISRI, TBG 129 and LBG 888 were selected as heat stress tolerant in terms of high seedling survival per cent and low per cent reduction in shoot and root growth. One genotype TBG 125 was selected as heat stress susceptible based on low seedling survival per cent and high per cent reduction in root and shoot growth. A field trial was conducted during summer 2020 with 10 blackgram genotypes replicated thrice in randomized block design. Morphological characters (leaf thickness, leaf pubescence, cuticle thickness, plant height), phenological characters (days to 50 % flowering, days tomaturity), physiological parameters such as SCMR, leaf area, dry matter (leaf, stem, root, pod), growth parameters (CGR, NAR, SLA, SLW, LAD), reproductive efficiency traits (Pollen viability per cent, flower to pod ratio), biochemical characters (super oxide dismutase, peroxidase, catalase) and yield related parameters were examined. Among the morphological characters studied, irrespective of the genotypes, leaf thickness showed a gradual increase from 20 DAS to 45 DAS and then declined. Plant height and leaf pubescence increased gradually throughout the crop growth stages in all the genotypes. Whereas cuticle thickness increased from 20 DAS to 60 DAS and decreased towards harvest. The Mean leaf thickness, leaf pubescence, plant height and cuticle thickness of tolerant xv genotypes were higher than susceptible genotype TBG 125. Among the tolerant genotypes, TBG 129, LBG 888 and PU 1504 recorded highest value of leaf thickness, leaf pubescence, plant height and cuticle thickness. Among the tolerant genotypes, LBG 982 completed crop cycle early with minimum days taken to 50 % flowering (34.67 days) and maturity (68 days). Thermosensitive genotype TBG 125 took more number of days to 50 % flowering and maturity compared to all other genotypes. Irrespective of the genotypes, leaf area, dry matter accumulation in roots, stem and leaves and SCMR values increased from 15 DAS to 60 DAS. Among the tolerant genotypes, LBG 888 and TBG 129 maintained higher leaf area, dry matter and SCMR values compared to all other genotypes. All genotypes recorded increased CGR, SLA, SLW and LAD from 15 DAS to harvest. The mean value of growth parameters viz., CGR, NAR, LAD and SLW of tolerant genotypes was higher than susceptible genotype TBG 125. Among the tolerant genotypes, LBG 888 and TBG 129 maintained highest values for all the above parameters whereas SLA was recorded highest for susceptible genotype TBG 125. High summer temperature during flowering time leads to reduction in pollen viability percentage in susceptible genotype TBG 125 which in turn causes flower abortion and thus number of flowers that converted into pods also decreased in susceptible genotype TBG 125 thus flower to pod ratio was lower in the genotype TBG 125. The specific activities of ROS scavenging enzymes such as super oxide dismutase, peroxidase, and catalase showed increased activity in tolerant genotypes. The increase of super oxide dismutase, peroxidase, and catalase was highest in tolerant genotypes LBG 888, TBG 129 and PU 1504 respectively. Among the tolerant genotypes, LBG 888, TBG 129 and PU 1504 which maintained higher growth and temperature tolerance attributes also recorded higher HI, yield and its components viz., No. of clusters/ plant, No. of pods/ cluster, No. of seeds/ pod, seed yield, pod yield, pod length, 100 seed weight, shelling percentage and HI. Under summer conditions, susceptible genotype TBG 125 reported lower yields as this genotype documented lower physiological attributes and temperature susceptibility characteristics. Among the nine tolerant blackgram genotypes and one susceptible genotype selected through TIR technique based on seedling survival percentage, per cent reduction in shoot and root growth, three genotypes viz., LBG 888, TBG 129 and PU 1504 were identified as heat stress tolerant. The traits related to heat tolerance was relatively better in these three genotypes in terms of physiological, biochemical, reproductive behavior and these characters were positively associated with seed yield under high temperature condition. Thus the genotypes LBG 888, TBG 129 and PU 1504 can be used in crop improvement programme for heat tolerance and higher yield.
