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.

Lal Bahadur Shastri, the then Hon`ble Prime Minister of India... 1964-66: The report of the Second National Education Commission headed by Dr. D.S. Kothari, Chairman of the University Grants Commission stressed the need for establishing at least one Agricultural University in each Indian State... 23, June 1966: Inauguration of the Administrative building of the university by Late Smt. Indira Gandhi, the then Hon`ble Prime Minister of India... July, 1966: Transfer of 41 Agricultural Research Stations, functioning under the Department of Agriculture... May, 1967: Transfer of Four Research Stations of the Animal Husbandry Department... 7th November 1996: Renaming of University as Acharya N. G. Ranga Agricultural University in honour and memory of an outstanding parliamentarian Acharya Nayukulu Gogineni Ranga... 15th July 2005: Establishment of Sri Venkateswara Veterinary University (SVVU) bifurcating ANGRAU by Act 18 of 2005... 26th June 2007: Establishment of Andhra Pradesh Horticultural University (APHU) bifurcating ANGRAU by the Act 30 of 2007... 2nd June 2014 As per the Andhra Pradesh Reorganization Act 2014, ANGRAU is now... serving the students and the farmers of 13 districts of new State of Andhra Pradesh with renewed interest and dedication...

    OCTOR OF PHILOSOPHY IN AGRICULTURE (GENETICS AND PLANT BREEDING)
    (Acharya N G Ranga Agricultural University, Guntur) RUPESH KUMAR REDDY, B; HARIPRASAD REDDY, K
    The present investigation was carried out as two separate experiments subjecting seven varieties of mungbean in half diallel to study combining ability, heterosis, generation mean analysis and character association for yield, yield attributes and water use efficiency related traits at dry land farm of Sri Venkateswara Agricultural College, Tirupati, Andhra Pradesh. The analysis of variance revealed that significant differences were existed in the mean performance of seven parents and 21 F1s for all the fourteen traits. Based on per se performance the parents viz., MGG 390, AKM 9904, LM 95, ML 267 and EC 362096 were adjudged as the best among seven parents and crosses involving these parents may throw desirable segregants for yield, yield attributing, water use efficiency and heat stress tolerance related traits. The cross combinations viz., MGG-390 × LM-95, LM 95 × EC 362096 and ML 267 × LGG 528 recorded high per se performance for yield, WUE and heat stress tolerance related attributes. The studies on combining ability revealed that mean squares due to gca and sca were highly significant for all the characters under study indicating the importance of both additive and non-additive gene action in the inheritance of the characters. The ratio of gca variance to sca variance was less than unity conforming the predominance of the non-additive gene action for all the traits under study except for plant height. An overall appraisal of gca effects revealed that the parents ML 267, EC 362096 and MGG 390 were identified as good xvii combiners for majority of the characters. Three crosses viz., ML 267 × LGG 528, MGG 390 × LM 95, LM 95 × EC 362096 were identified as the best specific combiners as these exhibited significantly high sca effects for majority of the yield, WUE and heat stress tolerance related components in desirable direction. Hence, these crosses could be utilized in further breeding programmes to isolate desirable segregants by pedigree method followed by selection in later segregating generations. Heterosis studies revealed that the cross combinations viz., LM 95 × EC 362096, MGG 390 × LM 95 and ML 267 × LGG 528 were adjudged as the best for majority of the yield, WUE and heat tolerance attributed traits. Based on the mean performance, combining ability and heterosis estimates, three cross combinations viz., LM 95 × EC 362096, ML 267 × LGG 528 and MGG 390 × LM 95 were found to be superior for yield, WUE and heat stress tolerance related characters. Hence, these crosses could be suggested for exploiting in future breeding programmes for obtaining transgressive segregants with high yield coupled with high WUE and heat tolerance. Correlation studies in F2 populations of three identified superior crosses viz., LM 95 × EC 362096, MGG 390 × LM 95 and ML 267 × LGG 528 revealed that improvement in seed yield coupled with drought and heat stress tolerance could be brought through component characters like number of pods per plant, number of clusters per plant, number of pods per cluster, plant height, branches per plant, SLA, SCMR, SLW and relative injury. Analysis of the results of path analysis for seed yield revealed that direct effect of number of pods per plant was high and positive in all the three F2 populations of ML 267 × LGG 528, MGG 390 × LM 95 and LM 95 × EC 362096. It indicates that this trait is the major contributing factor to seed yield and hence emphasis should be given to this character while making selection for realizing improvement in seed yield in mungbean. Generation mean analysis carried out using six basic generations (P1, P2, F1, F2, B1 and B2) of three selected superior crosses viz., ML 267 × LGG 528, MGG 390 × LM 95 and LM 95 × EC 362096 indicated that F1 means exceeded better parent values in respect of majority of the characters under study indicating presence of over dominance. However, F1 performance did not surpass better parent for days to 50% flowering, days to maturity, SLW and relative injury in all the three crosses. The F2 means were lesser than the F1 means for most of the traits. The means of backcross populations tended towards their respective parents. These results indicated predominant role of non-additive gene action which includes both dominance as well as epistatic interactions. Additive, dominance and epistatic effects contributed significantly for the inheritance of yield, yield attributes and water use efficiency related traits studied in all the three crosses. Hence, these crosses could be improved by exploiting both additive and non-additive types of gene effects through intermating of superior segregants at early generations followed by selection with pedigree method. xviii A good number of transgressive segregants in desirable direction were observed for yield, water use efficiency and heat stress tolerance related traits in all the three crosses. These transgressive segregants would greatly help in the development of improved cultivars with high yield and tolerance to drought and heat stress.
