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.

    GENETIC ANALYSIS OF YIELD, YIELD ATTRIBUTES AND DROUGHT TOLERANT TRAITS IN MUNGBEAN [Vigna radiata (L.) Wilczek]
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) GOVARDHAN, G; HARIPRASAD REDDY, K
    The present investigation entitled “Genetic analysis of yield, yield attributes and drought tolerant traits in mungbean (Vigna radiata (L.) Wilczek)” was conducted as three seperate experiments during kharif 2012, kharif 2013 and kharif 2014. Each experiment was carried out in field condition as well as under rainout shelter (17m × 7.5m) located at dry land farm of Sri Venkateswara Agricultural College, Tirupati. Sufficient irrigation was provided to one set upto field capacity, whereas other was imposed to moisture stress from 42 days to maturity through rainout shelter. This investigation were carried out systematically to study the nature of genetic variability, character association, combining ability, heterosis and generation mean analysis for yield, yield attributes and drought related traits. In experiment-I, fifty eight mungbean genotypes including four checks were evaluated by adopting augmented block design-II having 6 blocks and 4 checks. Analysis of variance revealed that significant differences among the genotypes for all the characters studied except relative water content. Estimates of phenotypic coefficient of variation (PCV) were higher than genotypic coefficient of variation (GCV) for all the characters. High to moderate GCV estimates and high heritability coupled with high genetic advance as per cent of mean were observed for relative injury, number of branches per plant, number of pods per cluster, specific leaf area, 100 seed weight, plant height, harvest index, SCMR and seed yield under both irrigated and moisture stress conditions suggesting that involvement of additive gene action for these characters. Hence, simple directional selection based on these characters in the segregating generations would be more effective and rewarding. Correlation analysis indicated that seed yield had positive and significant association with days to 50 per cent flowering, number of pods per cluster under irrigated condition and plant height under moisture stress condition harvest index. xvii However, under both irrigated and moisture stress conditions number of pods per plant and relative water content would be rewarding and simultaneous selection of these traits might bring an improvement in seed yield per plant coupled with drought tolerance. Path analysis revealed that, the traits viz., harvest index, pods per plant, pods per cluster, SCMR and relative water content had positive direct effect and significant association with seed yield per plant under both the conditions. Hence, these traits might be considered while constructing selection indices aiming for drought tolerant lines with high yield. In experiment-II, combining ability and heterosis studies were conducted with seven mungbean genotypes viz., MGG 347, MGG 351, LGG 460, LGG 528, KM 122, CN 9058 and VG 6197A which were selected based on mean performance in earlier season. These were crossed in half diallel fashion and resulted 21 F1 hybrids along with their parents were evaluated under two water regimes viz., irrigated and moisture stress condition. Based on per se performance and gca effects, four genotypes viz., MGG 347, MGG 351, LGG 460 and LGG 528 were identified as the best for improvement of yield and drought tolerance traits. The crosses viz., MGG 347 × MGG 351, MGG 351 × LGG 460 and LGG 460 × LGG 528 were identified as best specific cross combinations as these exhibited significantly high sca effects for seed yield per plant along with one or a few drought related traits in desirable direction. Hence, these crosses are reliable for further drought tolerance breeding where intermating approach followed by selection in their later segregating generations could be practiced for isolation of high yielding lines with drought tolerance. Heterosis studies revealed the crosses viz., MGG 347 × MGG 351 for SCMR, chlorophyll stability index and seed yield per plant; MGG 351 × LGG 460 for relative water content, relative injury and seed yield per plant maintained consistent relative heterosis, heterobeltiosis, standard heterosis under both the conditions. Further, the cross LGG 528 × CN 9058 for specific leaf area, MGG 347 × KM 122 for relative injury, MGG 351 × VG 6197A for chlorophyll stability index under moisture stress conditions exhibited significant heterobeltiosis. Similarly, the crosses MGG 347 × CN 9058 for SCMR and KM 122 × VG 6197A for chlorophyll stability index exhibited standard heterosis under both irrigated and moisture stress conditions. Hence, these crosses were emerged out as best specific combinations for their respective characters and could be utilized for obtaining transgressive segregants with high yield coupled with drought tolerance ability in advanced generations. In experiment-III, generation mean analysis was conducted using basic six generations (P1, P2, F1, F2, B1 and B2) of three selected crosses viz.,. MGG 347 × MGG 351, MGG 351 × LGG 460 and LGG 460 × LGG 528. Significance one or more scaling tests viz., A, B, C and D in most of the traits indicated the presence of digenic non-allelic interactions in the inheritance of these traits. Though both additive and non additive gene actions were significant, non additive gene action played predominant role in the inheritance of the traits. It was found that the cross MGG 347 × MGG 351 was the most promising for seed yield, yield attributes and drought related traits based on mean performance. Majority of the traits were found to be under the influence of duplicate type of epistasis for which one or two cycles of recurrent selection followed by pedigree breeding would be effective to modify the genetic architecture of mungbean for attaining higher yield with drought tolerance.
