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 AND MOLECULAR CHARACTERIZATION OF COTTON (Gossypium hirsutum L.)
    (Acharya N.G. Ranga Agricultural University, 2018) ANJANI, ALLURI; PADMA, V
    The present investigation was carried out during kharif 2017-18 at Regional Agricultural Research Station, Lam and APGC, Lam, Guntur to characterize 40 genotypes of cotton (G. hirsutum) using DUS characterstics of PPV & FRA and SSR markers and also to study the variability, heritability, genetic advance as per cent of mean, and genetic divergence of seed cotton yield per plant and yield component traits. The data were recorded on 20 descriptors viz., leaf colour, leaf hairiness, leaf appearance, gossypol glands, leaf nectaries, leaf petiole pigmentation, leaf shape, stem hairiness, stem pigmentation, bract type, petal colour, petal spot, stigma position, anther filament colouration, pollen colour, boll bearing habit, boll colour, boll shape, boll surface, prominence of boll tip and 14 quantitative characters viz., plant height (cm), days to 50 % flowering, number of monopodia per plant, number of sympodia per plant, number of bolls per plant, boll weight (g), seed index (g), lint index (g), ginning outturn (%), 2.5% span length (mm), uniformity ratio, micronaire value (10-6 g/inch), bundle strength (g/tex) and seed cotton yield per plant (g). The morphological descriptors indicated variability for eight characters (leaf petiole pigmentation, stem pigmentation, petal colour, stigma position, pollen colour, boll shape, boll surface, prominence of boll tip) out of twenty characters studied and these traits are helpful for the identification of the genotypes from one another and some of the characters like stem hairiness, can be exploited for breeding pest resistant genotypes. The genotypic coefficients of variation for all the characters studied were lesser than the phenotypic coefficients of variation indicating the masking effect of environment. Wide genetic variability was observed for the characters viz., plant height, number of sympodia per plant, number of bolls per plant, boll weight and seed cotton yield per plant. High heritability coupled with high genetic advance as per cent of mean was recorded for seed cotton yield per plant indicating the preponderance of additive gene action and hence further improvement may be done through simple selection procedures. The results of Mahalanobis D2 analysis indicated the presence of considerable genetic divergence among the 40 genotypes and the traits bundle strength, days to 50% flowering, number of monopodia per plant, 2.5% span length and boll weight contributed maximum towards genetic divergence. The 40 genotypes were grouped into 7 clusters using Tocher’s method indicating genetic diversity and geographical diversity were not related. The cluster I had the maximum number of genotypes while the intra-cluster distance was maximum in the cluster II. The clusters III, IV, V, VI, and VII were solitary clusters. The inter cluster distance was maximum between clusters II (SCS 1061, CCH 14-2, TSH 0533-1, RS 2767, SCS 1207, L 1008, CCH 14-1, GJHV 510, BS 26) and VI (BS 23) indicating the importance of genotypes present in these clusters in hybridization programme for the exploitation of heterosis. The cluster II recorded the highest mean values for the quality traits and seed cotton yield per plant and these genotypes can be effectively exploited in the breeding programmes. In the present study, 40 genotypes were also screened with 50 SSR primers out of which 19 showed polymorphism and the PIC values were also higher for 17 primers indicating their usefulness in characterization. The jaccard’s similarity coefficient values ranged from 0.03 to 0.80 indicating that the cultivars have a vast genetic base. The genotypes, RAH 1033 and L 788 showed least similarity coefficient value among the genotypes revealing their use in hybridization programme for generating variability and production of transgressive segregants in the future generations. The genotypes were grouped into seven clusters using UPGMA method. The cluster I had nine genotypes while the cluster III was the second largest cluster with 11 genotypes. The cluster IV was the largest with sixteen genotypes. The clusters II, V, VI and VII were solitary clusters.
