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.

    MORPHOLOGICAL, BIOCHEMICAL AND MOLECULAR CHARACTERIZATION OF FOXTAIL MILLET [Setaria italica (L.) Beauv.] GERMPLASM
    (guntur, 2022-08-25) SANDHYA, MUNAGAPATI; RAMANA, J. V.
    The present study was carried out with the prime objective of assessing morphological, biochemical and molecular diversity in 100 genotypes of foxtail millet. The experiment was conducted at Regional Agricultural Research Station (RARS), Lam, Guntur in Augmented Randomized Complete Block Design (ARCBD) during kharif, 2017 and rabi, 2017-18. Morphological and biochemical data for 21 parameters collected from these genotypes was pooled over seasons and analyzed for divergence using Mahalanobis’ D2 statistic and PCA analysis. Molecular divergence was estimated using 85 SSR markers. Highly significant variability was observed among the 100 genotypes for plant height (PH), carbohydrate (CARB), calcium (Ca), carotene (CARO) and phenols (PHE); whereas moderate variability was observed for days to 50% flowering (DFF), panicle length (PL), days to maturity (DM), grain yield (GYP), protein (PRO) and folic acid (FOA). Eight genotypes viz. ISe 1286, ISe 751, ISe 1201, ISe 1181, ISe 1674, ISe 1511, ISe 1704 and ISe 1338 were observed to be superior for at least four nutritional parameters (carbohydrate (CARB), protein (PRO), fat (FAT), crude fibre (CF), calcium (Ca), iron (Fe), phosphorous (P), potassium (K), niacin (NI), thiamine (TH), carotene (CARO), phenols (PHE), folic acid (FOA), lysine (Lys)) while, the genotypes ISe 1286, ISe 1674, ISe 1511, ISe 1704 and ISe 1338 are calcium rich genotypes. High PCV and GCV (>20%) were recorded for majority of the traits viz. plant height (PH), panicle length (PL), test weight (TW), productive tillers per plant (NPT), grain yield (GYP), crude fibre (CF), calcium (Ca), iron (Fe), phosphorous (P), niacin (NI), thiamine (TH), carotene (CARO), folic acid (FOA) and lysine (Lys) indicating the presence of high amount of variability. Low PCV and GCV (20%) was reported for the traits, days to 50% flowering (DFF), plant height (PH), panicle length (PL), test weight (TW), productive tillers per plant (NPT), days to maturity (DM), protein (PRO), fat, crude fibre (CF), calcium (Ca), iron (Fe), phosphorous (P), niacin (NI), thiamine (TH), carotene (CARO), folic acid (FOA), lysine (Lys) and grain yield (GYP) indicating the operation of additive gene action in the expression and exploitation of these traits by simple selection is suggested for improvement. The correlation studies of present investigation had revealed that the dependent variable grain yield had significant positive correlation with days to 50% flowering (DFF), plant height (PH), panicle length (PL), no. of productive tillers (NPT), days to maturity (DM) and test weight (TW) indicating their key role in selection for improvement of grain yield/plant (GYP). Path analysis also revealed days to 50% flowering (DFF), plant height (PH), panicle length (PL), no. of productive tillers (NPT), days to maturity (DM) and test weight (TW) had true relationship with grain yield per plant (GYP) by establishing significant positive association and positive direct effect revealing their importance in selection of high yielding genotypes in foxtail millet. Mahalanobis’ D2 analysis indicated the presence of substantial diversity in the studied material by forming nine clusters and maximum number of genotypes were present in cluster I (58 genotypes) followed by cluster IV (20 genotypes), cluster II (nine genotypes) and cluster V (eight genotypes). Clusters III, VI, VIII and IX were solitary clusters containing single genotype, ISe 1789, ISe 1685, ISe 1181and ISe 1201, respectively. Among the characters studied highest percentage of contribution towards divergence was noted by grain yield/plant (38.22%) followed by productive tillers per plant (35.46%), plant height (21.21%) and phosphorus (1.9%). The maximum inter cluster distance was observed between clusters, VII and IX (46356.45), followed by clusters VIII and IX (30901.85) and clusters V and VII (27950.79) which suggested the presence of broad genetic divergence among these clusters and can be exploited to generate transgressive segregants for the desired traits. It is apparent that the productive crosses can be expected from ISe 969 (cluster VII with higher mean values for grain yield (GYP), test weight (TW), panicle length (PL), no. of productive tillers (NPT) and calcium (Ca)) with ISe 1201 of cluster IX (higher mean values for fat (FAT), potassium (K), thiamine (TH), folic acid (FOA) and lysine (Lys)) by considering significant divergence and higher mean values for yield and its contributing traits. The principal component analysis (PCA) indicated the contribution of first ten principal components for about 76.59% variability and the contribution of first principal component (PC1) towards variability was 17.651% while PC2 was 10.753% and PC3 was 9.189%. The traits, panicle length (PL), grain yield (GYP) and number of productive tillers (NPT) contributed maximum towards divergence in PC1. Two dimensional (2D) plot based on PCA scores showed that the genotypes ISe 710, ISe 1181, ISe 771 and ISe 969 were scattered relatively away from the other genotypes indicating their usefulness in hybridization programmes. Molecular divergence analysis with 85 simple sequence repeats (SSR) markers resulted thirty polymorphic markers. The Polymorphism Information Content (PIC) values ranged from 0.037 to 0.573 with the mean value of 0.30. High PIC markers with better discriminatory power were SICAAS4007, SICAAS2043, SICAAS6067 and SICAAS9130 and these can be used for diversity studies, gene mapping, molecular breeding and germplasm evaluation. The number of alleles per primer was varied from two to six with an average of 2.56 alleles per primer. The dendrogram prepared from the UPGMA grouped the genotypes into 3 clusters with similarity coefficient value of 0.69. Cluster I had fifty five genotypes and the similarity coefficient range was 0.27 to 0.50. Cluster II had two sub-clusters with similarity coefficient values ranged from 0.33 to 0.69 while cluster III had ten genotypes and the similarity coefficient values ranged from 0.23 to 0.58.The genotype, ISe 746, formed a separate sub-cluster in cluster III as IIIC indicating its’ differentiation from other genotypes of this cluster Morphological, biochemical and molecular diversity of 100 foxtail millet genotypes clearly reported the presence of huge variability for yield and quality parameters. The genotypes viz. Ise237, ISe 710, ISe 1685, ISe 1767, ISe 1773, ISe 1808, ISe 1859, Ise 1888, Ise 90, Ise 771 and Ise 969 recorded high grain yield whereas ISe 1227, ISe 1286, ISe, 1674, Ise 1312 and Ise 1320 are early maturing genotypes. The genotype, ISe 1286, is rich in eight nutritional parameters (protein (PRO), fat, calcium (Ca), iron (Fe), niacin (NI), phenols (PHE), folic acid (FOA) and lysine (Lys)).The superior millet genotypes identified with high yield and nutritive values can be explored for the identification, characterization and mining of genes/alleles governing these traits and this forms the future line of study for other researchers.
