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.

    GENOME WIDE ASSOCIATION STUDIES FOR GRAIN IRON AND ZINC CONTENTS IN CHICKPEA (Cicer arietinum L.)
    (Acharya N G Ranga Agricultural University, 2024-05-01) SRUNGARAPU RAJASEKHAR; Dr. LAL AHAMED M.
    Chickpea is a cheap source of protein and micronutrients to the poor people living in arid and semi-arid regions of Southern Asia and Sub-Saharan Africa and contribute towards reducing malnutrition resulting from protein and micronutrient deficiency. The current study evaluated chickpea reference set of 280 accessions (landraces, breeding lines, and advanced cultivars) to study the variability, diversity and to delineate the genetic nature of grain nutrient (protein, Fe, Zn content) and agronomic traits in normal (NS) and heat stress (HS) conditions using genome-wide association studies. The analysis of variance (ANOVA) revealed highly significant difference among the accessions for grain nutrients and agronomic traits under normal and heat stress seasons. Genetic diversity studies revealed a wide range of variability for grain protein (15.7–25.3%), Fe (44.8–74.9 mg kg-1 ) and Zn (38.4–65.7 mg kg-1 ) contents along with agronomic traits. The accessions, ICC 9848 (NS-Protein: 26.21%, Fe: 76.74 mg kg-1 , Zn: 55.74 mg kg-1 ; HS-Protein: 25.25%, Fe: 65.52 mg kg-1 , Zn: 59.71 mg kg-1 ), ICC 9895 (NS-Protein: 25.49%, Fe: 75.65 mg kg-1 , Zn: 52.48 mg kg 1 ; HS-Protein: 24.19%, Fe: 70.90 mg kg-1 , Zn: 59.92 mg kg-1 ), ICC 9862 (NS-Protein: 25.69%, Fe: 72.78 mg kg-1 , Zn: 52.53 mg kg-1 ; HS-Protein: 24.85%, Fe: 67.74 mg kg 1 , Zn: 63.27 mg kg-1 ) and ICC 9872 (NS-Protein: 25.70%, Fe: 69.85 mg kg-1 , Zn: 52.46 mg kg-1 ; HS-Protein: 25.13%, Fe: 73.84 mg kg-1 , Zn: 63.27 mg kg-1 ) were found promising for grain protein, Fe and Zn content across the environments. The kabuli accessions showed high average grain protein and Fe content when compared with the desi types. The PCV and GCV of nutrient traits was low to moderate across the environments. High heritability was noted for all the traits under individual seasons of normal and heat stress whereas pooled seasons noted moderate heritability for grain Fe and Zn contents. High heritability with high GAM was recorded for days to first flower, days to 50% flowering, plant height, number of filled pods per plant, number of unfilled pods per plant, number of pods per plant, number of seeds per plant, 100 seed weight, harvest index and seed yield across the environments. The xvii association among the nutrient traits across the environments was positive and was negative with seed yield. The principal component analysis revealed first four PCs under normal season1 (NSI) and three PCs under normal season2 (NSII), Pooled and heat stress (HS) contributed maximum per cent of total variation for nutrient and agronomic traits. Cluster analysis grouped the accessions into two clusters across the environments. GT biplot identified the accessions, ICC 9848, ICC 9872, ICC 9895 and ICC 9862 with high grain protein and Fe content; ICC 1161, ICC 8522 and ICC 2242 with high Zn content; and ICC 6874 and ICC 1392 with high values for seed yield over the seasons. The genotyping of chickpea reference set using mid-density 5k SNP array panel resulted in 4603 highly informative SNPs distributed across the chickpea genome. Population structure analysis revealed three subpopulations (K=3) in the reference set. PCA using SNP markers data revealed three distinct clusters where PC1 explained 38.2% and PC2 revealed 9.31% of total variance. The unweighted neighbor-joining (NJ) tree method grouped the accessions into three clusters. Linkage disequilibrium (LD) was extensive across the chickpea genome and LD decay was relatively low at a physical distance of 4032Kb across the genome. Genome-wide association analysis revealed a total of 20 and 73 marker-trait associations (MTAs) for grain nutrient and agronomic traits over normal seasons while a total of 11 and 45 MTAs were significantly associated with grain Fe and agronomic traits under HS using FarmCPU and BLINK models. The marker, S4_4477846 on chr4, was found to be co-associated with grain protein over seasons. The markers, S1_11613376 and S1_2772537 on chr1, co-associated with grain Fe content under NSII and pooled seasons and the marker, S7_9379786 on chr7, was co associated with grain Fe content under NSI, pooled and HS. SNP annotation of associated markers was found to be related to gene functions of metal ion binding, transporters, protein kinases, transcription factors, and many more functions involved in plant metabolism along with Fe and protein homeostasis. The identified significant MTAs require further validation and characterization to elucidate the exact role of these genes in chickpea. Further, it was noted, 92.9%, 74.3% and 10.4% of the accessions showed reduction of ~25% of grain protein, 22% of Fe and 16% of Zn under heat stress. The accessions, ICC 9848, ICC 9895, ICC 9862 and ICC 9872 were least affected by heat for protein, ICC 9895 and ICC 9643 for grain Fe content can be exploited in breeding programmes to develop nutrient-rich climate resilient chickpea cultivars. The present study highlighted the use of chickpea reference set for exploitation in marker-assisted selection to develop nutrient dense climate resilient chickpea varieties
