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.

    STUDIES ON GENETIC DIVERSITY OF PROMISING SLENDER GRAIN GENOTYPES IN RICE (Oryza sativa L.)
    (Acharya N G Ranga Agricultural University, 2023-12-02) A. ARUN KUMAR; Y. SUNEETHA
    The present investigation entitled “Studies on genetic diversity of promising slender grain genotypes in rice (Oryza sativa L.).” was carried out during Kharif, 2020 at Agricultural Research Station, Bapatla with 30 slender grain rice genotypes, sown in a randomized block design with three replications and observations were recorded on 16 yield, yield component and quality characters. The experiment was carried out with the objective of identifying slender grain genotypes with high yield and good quality, in addition to estimation of genetic diversity, genetic parameters, character associations and path studies to aid in the improvement of slender grain rice genotypes. Analysis of variance revealed the existence of significant differences among the 30 genotypes for all the characters studied. The estimates of GCV, PCV, heritability, and genetic advance as per cent mean were observed to be high for ear bearing tillers per plant, panicle length, grains per panicle, test weight, gran yield per plant, protein content and zinc content, indicating the effectiveness of direct selection for improvement of these traits. However, low GCV, PCV, heritability and genetic advance as per cent mean were observed to be low for the quality traits, namely, hulling, milling and head rice recovery percentage in addition to volume expansion ratio, indicating the ineffectiveness of direct selection for these traits. A perusal of the results on character associations and path effects revealed high positive direct effect for ear bearing tillers per plant, panicle length, grains per panicle, test weight, protein content and zinc content in addition to significant and positive association with grain yield per plant. Hence, these traits are inferred as important selection criterion and direct selection for the traits is recommended for yield improvement in slender grain rice improvement programmes. Further, the quality traits namely., hulling and milling percentage, head rice recovery percentage, water uptake and amylose content had recorded low to moderate positive direct effects on grain yield per plant. However, association of these traits was noticed to be positive with grain yield per plant indicating indirect effects to be the cause of correlation and hence, the need for consideration of indirect causal factors during selections for yield improvement through these traits. xiii Studies on genetic divergence of genotypes resulted in their grouping into five clusters. Among them cluster I was the largest cluster with 25 genotypes, followed by Cluster IV with two genotypes. The clusters II, III, V were monogenotypic with one genotype in each cluster. Maximum inter-cluster distance was observed between Cluster V and Cluster III, indicating a scope for realization of transgressive seggregants from hybridization between the genotypes of Cluster III and Cluster V. The results on cluster means revealed high cluster means for Cluster III for grain yield per plant, test weight, panicle length, hulling percentage and zinc content. The cluster V had also recorded greater plant height, milling percentage, head rice recovery percentage and protein content. Hybridizaton of the genotypes belonging to cluster III and V is suggested for obtaining of high yielding transgressive segregants with good quality. Further, maximum contribution towards genetic divergence was noticed by grain yield per plant (22.40 %), followed by grains per panicle (18.50 %) and iron content (12.21 %). The results on Principal Component Analysis (PCA) revealed first five principal components with eigen value more than one. These principal components were observed to contribute to 72.5611 per cent towards the total variability. The first principal component (PC 1) contributed maximum towards divergence (22.8344 %). The two-dimensional scatter diagram revealed 18 different clusters. Among these, 11 clusters were noticed to be monogenotypic. The pattern of distribution of the genotypes in these clusters was observed to be at random with no reference to geographical diversity. Molecular characterization of the slender grain rice genotypes with 14 SSR markers revealed polymorphism for ten markers. The allele number ranged from two to three alleles per locus and PIC values ranged from 0.287 to 0.666. The markers, RM 33825, RM 167 and RM544 were highly informative, while the markers, namely, RM231, RM12292, RM670, RM447, RM5791 and RM24 were moderately informative. Cluster analysis and dendrogram construction by UPGMA (Unweighted Pair Group Method with Arithematic Averages) based on Jaccard’s similarity coefficient using NTSYS 2.0 version resulted in grouping of the genotypes into three major clusters. Cluster I comprised of 17 genotypes and was further divided into five sub-clusters (IA, IB. IC, ID and IE). Cluster II contained 13 genotypes and was further divided into four sub-clusters (IIA, IIB, IIC and IID). Cluster III comprised of two genotypes only. The study identified MTU 2374-129-1-6, JMP 12, JMP 35, MTU 2404-111-1-1, BPT 3082 and JMP 186 as promising high yielding slender grain genotypes with good quality.
