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.

    IDENTIFICATION OF HOMOZYGOUS LINES HAVING BLAST AND BACTERIAL LEAF BLIGHT GENES THROUGH MARKER ASSISTED SELECTION IN BLACK RICE (Oryza sativa L.)
    (guntur, 2022-08-23) NOOR AHMED, SHAIK; SHESHU MADHAV, M.
    North Eastern states of India have rich diversity in rice and black aromatic glutinous rice of Manipur is having commercial importance. Three traditional black rice varieties i.e., Chakhao poireiton, Chakhao amubi and Black chakhao are popular and Chakhao poireiton is under high acreage in North East India. This black rice is a poor yielder and susceptible to major biotic stresses like blast and bacterial leaf blight (BLB). Chakhao poireiton parent was screened phenotypically for blast and for BLB and also genotypically screened using gene specific markers for blast (Pi54, Pi2) and BLB (Xa21, xa13, xa5) genes. Both phenotyping and genotyping results have shown that Chakhao poireiton was having high susceptibility to both blast and BLB and all the five genes were found to be absent. The present investigation was attempted to pyramid BLB and blast genes in to Chakhao poireiton using marker assisted backcross breeding. SM2545 was the donor for blast resistant genes (Pi54, Pi2), while Improved Samba Mahsuri was the donor for bacterial leaf blight genes (Xa21, xa13 and xa5). The validation of parents for the target genes was done by employing RM206 (SSR marker) for Pi54 gene, AP5659-5 marker for Pi2 gene, pTA248 (STS marker) for the gene, Xa21, xa13-promo (functional marker) for xa13 gene and xa5FM marker for xa5 gene and the parents (donor and recurrent) showed polymorphism for selected target markers. Two crosses (Chakhao poireiton × ISM and Chakhao poireiton × SM2545) were attempted. From both the crosses, hybrids were confirmed and from the each cross one hybrid plant was carried forward to generate BC2F2 and BC2F3. At each backcross, foreground selection to identify the plants carrying the target genes and xiii background selection to identify lines with the highest recurrent parent genome. Out of 400 BC2F2 plants screened, eight plants showed heterozygosity for all the five target genes (Pi54, Pi2, Xa21, xa13 and, xa5). Background analysis was done using 106 polymorphic markers in eight plants BC2F2 generation to know the best plant possessing maximum introgression of recurrent parent genome (RPG). Background analysis of lines revealed that six plants had highest RPG of more than 90%. Agro-morphological evaluation was done in 8 BC2F2 plants during kharif 2019-2020 at IIRR, Hyderabad. BC2F2 plants carrying all five genes in heterozygous condition along with maximum RPG were selfed for generate BC2F3 plants. Blast screening of BC2F3 plants showed that the plants 124-1-5 and 121-1-13 were having disease score of „1‟. All the selected BC2F3 plants were screened for BLB and high level of resistance with „1‟ disease score was observed in two plants (124-1-5 and 121-1-13) of 8 plants having all the five genes whereas the remaining plants showed disease score of 2-3. In the present study genotyping in BC3 derived lines resulted that, four lines 124-1-5-1-5, 124-1-5-1-14, 124-1-5-2-4 and 124-1-5-2-5 were having all the five genes, some genes are in heterozygous condition. Among the four BC3 lines, 124-1-5 -1-14 has four genes in homozygous condition and one gene Pi2 is in heterozygous condition.

    STUDIES ON COLLAR ROT OF CHICKPEA CAUSED BY Sclerotium rolfsii Sacc.
    (ACHARYA N G RANGA AGRICULTURAL UNIVERSITY, GUNTUR, 2019) NOOR AHMED, SHAIK; KHAYUM AHAMMED, S
    The present investigation was carried out to study the collar rot of chickpea caused by Sclerotium rolfsii Sacc. Chickpea is an important cool season food crop grown mainly in dry land which is a rich source of protein and enriches soil fertility by biological nitrogen fixation. The collar rot disease of chickpea is soil borne and fast spreading pathogen accounts for 55-95% mortality of the seedlings of the crop during favourable environment. During Rabi 2017, diseased samples were collected from major chickpea growing mandals of Kurnool and YSR Kadapa districts and nineteen S. rolfsii isolates were isolated, which were designated as CSR 1 to CSR 19. Pathogenicity test of S. rolfsii isolates on chickpea susceptible variety, L 550 revealed that, S. rolfsii isolate CSR 10 was identified as most virulent isolate. During Rabi 2018-19, a roving survey was conducted to assess the occurrence of chickpea collar rot disease incidence in Kurnool district of Andhra Pradesh recorded that the disease incidence was highest in Alluru village (18.0%) and lowest incidence of 3.6% was recorded in Bandiatmakur village. The incidence ranged from 3.60 to 18.00 per cent due to monocropping and time of sowing in high moist conditions during the last week of october to second week of november. Among sixteen advanced breeding lines screened in screening block, two lines showed resistant reaction, six lines showed moderately resistant reaction, four lines showed moderately susceptible reaction, four lines showed susceptible reaction and none was highly susceptible. Among 17 genotypes from IIPR, Kanpur screened under pot culture, one genotype showed resistant reaction, four genotypes showed moderately resistant reactions, six genotypes showed moderately susceptible reaction, six genotypes showed susceptible reaction and none was highly susceptible. The influence of three different dates of sowing employing three chickpea varieties was studied on growth, occurrence of collar rot, soil moisture, inoculum load and other yield parameters of chickpea. NBeG 49 sown at 19th november showed highest germination and significantly lowest germination was observed in JG 62 sown at 19th november. NBeG-49 sown at 15th october showed highest disease incidence and lowest disease incidence in variety JG-62 when sown at 30th october. Highest soil moisture was recorded with NBeG-49 sown at 15th october and lowest soil moisture with JG-62 sown at 30th october. However, highest inoculum load was observed with NBeG-49 sown at 15th october and lowest in JG-62 sown at 30th october. JG-62 sown at 30th october showed highest shoot length, root length and dry weight of plant and lowest shoot length, root length and dry weight of plant in NBeG-49 sown at 15th october. Highest yield was recorded with JG-62 sown at 30th october and lowest yield in NBeG49 sown at 15th october. The antagonistic effect of ten Trichoderma isolates and ten Pseudomonas fluorescens isolates were assessed against S. rolfsii by dual culture technique. Among the Trichoderma isolates highest inhibition was observed with CRT 8 and among P. fluorescens isolates highest inhibition was observed with CPF 3. Among the eight fungicides tested against S. rolfsii under in vitro conditions, combination of strobilurin and triazole fungicides, tebuconazole 60 FS and carboxin 37.5% + thiram 37.5% WS were highly effective and completely inhibited the mycelial growth of the pathogen at all four concentrations. Lowest inhibition percentage (53.33%) was recorded with carbendazim 12% + mancozeb 63% WP at 500ppm. Compatibility among effective fungicides on the effective Trichoderma isolates (CRT-8) has revealed that carboxin 37.5% + thiram 37.5% WS showed its compatibility with effective Trichoderma isolates and did not affect the mycelial growth of Trichoderma isolates, and this fungicide was used for pot culture study. Efficacy of effective fungicide and bioagent was tested against S. rolfsii through pot culture under greenhouse conditions. Among different treatments T8 (Seed treatment with carboxin 37.5% + thiram 37.5% WS @ 1.5gm/kg seed, Seed treatment with CRT-8 @ 10gm/kg seed, Soil drenching with carboxin 37.5% + thiram 37.5% WS @ 1.5gm/kg soil and Soil application with CRT8+FYM @ 8gm/kg FYM) showed lowest per cent disease incidence (16.67%) with highest germination percentage (100.00%), root length (8.19cm), shoot length (30.77cm) and dry weight (1.15gm). From the study it was clear that integrated treatment T8 is highly effective with highest chickpea seed germination, root length, shoot length, dry weight of the plant and least disease incidence.
