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.

    MARKER ASSISTED INTROGRESSION OF DROUGHT TOLERANCE AND PHOSPHORUS UPTAKE QUANTITATIVE TRAIT LOCI INTO RICE (Oryza sativa L.)
    (Acharya N.G. Ranga Agricultural University, Guntur, 2021-12-06) KAVITHA, GALIPOTHULA; . REDDI SEKHAR, Dr. M
    The present investigation was carried out with breeding material consisting 24 BILs of qDTY3.1 positive lines and 26 BILs of Pup1 positive lines along with two recurrent parents IR58025B and KMR-3R and two QTL donors viz., Apo for qDTY3.1 QTL and Kasalath for Pup1 QTL respectively. The genetic materials of different generations viz., F1, BC1F1, BC2F1 and BC2F2 of two crosses IR58025B x Apo and KMR-3R x Kasalath were developed during kharif 2016 to rabi 2018 by using introgressive backcrossing of marker selected QTL genotypes with recurrent parents involving precise foreground and background selection strategy. RM 520 SSR marker was used for the foreground selection of the qDTY3.1 in F1, BC1F1, BC2F1 and BC2F2 generations of IR58025B x Apo while background selection was performed for the same set of BILs with 88 polymorphic SSR markers. Foreground selection of Pup1 QTL was done with two SSR markers viz., K-46-1 and K-46-2 in F1, BC1F1, BC2F1 and BC2F2 generations of KMR-3R x Kasalath. Inaddition, 86 polymorphic SSR markers were used for background selection in BILs of KMR-3R x Kasalath. The BILs identified from BC2F2 generation of each cross were evaluated in two separate experiments during rabi 2018 at IIRR, Rajendranagar, Hyderabad in a completely randomised block design with two replications under both control (non-stress) and stress condition. The experiment-I consisted of 24 BILs of qDTY3.1 positive lines derived from BC2F2 generation of cross IR58025B x Apo and were evaluated at IIRR, Rajendranagar, Hyderabad during rabi 2018 under both control and reproductive stage moisture stress conditions in order to identify backcross inbred lines with higher grain yield under reproductive stage moisture stress. xv Analysis of variance revealed the existence of significant differences among the BILs in both reproductive stage moisture stress and control conditions for all traits except for panicle length. Correlation analysis revealed highly significant positive association of grain yield per plant with harvest index, filled grains per panicle, spikelet fertility and biological yield per plant under both control and moisture stress whereas plant height, number of tillers per plant, number of panicles per plant, 1000 grain weight, shoot length and SCMR showed significant positive association under reproductive stage moisture stress. Seven BC2F2 introgressive lines viz., GSD-2, GSD-4, GSD-12, GSD-16, GSD-20, GSD-21 and GSD-23 were selected as qDTY3.1 positive lines with higher yield under both control and reproductive stage moisture stress conditions respectively and could be promising donors for improvement of rice cultivars for reproductive stage moisture stress condition. The experiment-II comprised of twenty six Pup1 positive back cross inbred lines (BC2F2) derived from crossing of KMR-3R with Kasalath and were evaluated at IIRR, Rajendranagar, Hyderabad during rabi, 2018 on experimental fields at normal P (> 18.3 ppm) and low P (< 2 ppm) conditions so as to identify the backcross inbred lines with higher grain yield under low P deficient conditions. Analysis of variance indicated the existence of significant differences among the BILs in both low P and normal P environments for all traits except for number of tillers per plant, number of panicles per plant and unfilled grains per panicle. A perusal of character association indicated highly significant positive association of grain yield per plant with harvest index, spikelet fertility and leaf P in both conditions. Number of tillers per plant, number of panicles per plant, filled grains per panicle and leaf P displayed significant positive association with grain yield per plant under low P conditions. Seven BC2F2 introgressive lines viz., GSP-2, GSP-4, GSP-12, GSP-16, GSP-20, GSP-23 and GSP-26 were confirmed as Pup1 QTL positive lines with higher grain yield under both low P and normal P conditions and could be utilized in breeding programme for development of cultivars of rice for low ā€˜Pā€™ condition.

    EVALUATION OF GROUNDNUT (Arachis hypogaea L.) GENOTYPES FOR POD YIELD AND ITS COMPONENT TRAITS
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) KAVITHA, GALIPOTHULA; REDDI SEKHAR, M
    The experimental material consisted of fifty genotypes of groundnut which were evaluated at dry land farm of S.V. Agricultural College, Tirupati during kharif, 2014 so as to identify the genotypes with high yield and water use efficient genotypes. The analysis of variance revealed the existence of significant differences among the genotypes for all the traits studied. The genotypes viz., MLTG(SB)-3, MLTG(SB)-6, MLTG(VB)-11 and MLTG(VB)-2 showed high mean performance for pod yield and its components viz., number of primary branches per plant, number of sound mature kernels per plant, pods per plant, kernel yield per plant (g), leaf nitrogen (%) content at 60 DAS, leaf nitrogen (%) content at 80 DAS and shelling percentage. The estimates of genetic parameters revealed that dry matter per plant, number of sound mature kernels per plant, kernel yield per plant, pod yield per plant and number of primaries per plant registered high GCV and PCV estimates. High heritability (broad sense) was observed for all the traits. High GAM was recorded for dry matter per plant, number of sound mature kernels per plant, pod yield per plant, number of primary branches per plant, number of pods per plant, specific leaf area at 60 DAS, number of seeds per pod, shelling percentage and specific leaf area at 80 DAS indicating that these traits can be further improved by simple selection in the present breeding material. The D2 analysis revealed that the 50 genotypes had considerable amount of diversity and grouped into five clusters. Inter cluster indicated that clusters III and V were quite distant apart followed by IV and V, I and V, III and IV, I and IV and II and III in decreasing order of genetic distance. Hence, genotypes for these clusters namely MLTG(SB)-6, MLTG(VB)-9, MLTG(VB)-2, MLTG(VB)-11, Abhaya, IET-1531, INS-II-15 and AVT(D)1429 (Cluster-I), MLTG(SB)-3 and MLTG(SB)-2 (Cluster-II), TCGS 320 (Cluster-III), K-6 (Cluster-IV) and MLTG(SB)-12 (Cluster-V) were suggested for inclusion in hybridization programme for obtaining superior and desirable recombinants. Further, canonical root analysis confirmed the clustering pattern obtained by D2 analysis. A perusal of character association indicated highly significant positive association of kernel yield per plant with pod yield per plant. The other traits viz., number of sound mature kernels per plant, number of primary branches per plant, dry matter per plant, leaf nitrogen (%) content at 60 DAS and specific leaf area at 80 DAS exhibited significant positive association with pod yield per plant (g). These characters also exhibited strong and positive inter-se associations among themselves. Path coefficient analysis revealed that kernel yield per plant exerted the highest positive direct effect on pod yield per plant. It was also revealed that number of primary branches per plant, number of sound mature kernels per plant and leaf nitrogen (%) content at 60 DAS contributed indirectly to pod yield per plant through kernel yield per plant. These characters also exhibited highly significant positive association with pod yield as well as among themselves. Hence, these characters should be given due emphasis in formulating selection criterion for genetic improvement of pod yield potential with high water use efficiency in the present genetic material.
