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.

    GENETIC DIVERGENCE IN UPLAND COTTON (Gossypium hirsutum L.)
    (Acharya N.G. Ranga Agricultural University, Guntur, 2015) PRADEEP, SEEPANA; Dr. Y. SATISH
    The present investigation was carried out during Kharif, 2014-15 at Regional Agricultural Research Station, Lam farm, Guntur, Andhra Pradesh to characterize 60 genotypes of cotton (Gossypium hirsutum L.), to study the variability, heritability, genetic advance as per cent of mean, genetic divergence, character association and the magnitude of direct and indirect effects of 15 yield component traits with seed cotton yield per plant viz., plant height, days to 50% flowering, number of monopodia, number of sympodia per plant, number of bolls per plant, boll weight (g), ginning outturn (%), seed index (g), lint index (g), 2.5% span length (mm), micronaire (10-6g/in), bundle strength (g/tex), uniformity ratio, seed cotton yield per plant (g) and lint yield per plant (g). The genotypic coefficients of variation for all the characters studied were lesser than the phenotypic coefficients of variation indicating the masking effect of the environment. Moderate to high variability and high heritability coupled with high genetic advance as per cent of mean was observed for plant height, number of monopodia per plant, number of bolls per plant, lint index, seed cotton yield per plant and lint yield per plant indicating the predominance of additive gene action and hence, direct phenotypic selection may be useful with respect to these traits. Correlation study revealed that plant height, number of monopodia per plant, number of sympodia per plant, number of bolls per plant, boll weight, ginning out turn, seed index, lint index and lint yield per plant had positive significant association with seed cotton yield per plant. The path analysis indicated that plant height, number of monopodia per plant, number of sympodia per plant, number of bolls per plant, boll weight, ginning out turn, seed index, lint index and lint yield per plant showed positive and significant correlation, direct selection based on these attributes may be helpful in evolving high yielding varieties of upland cotton. The results of multivariate analysis indicated the presence of considerable genetic divergence among the 60 genotypes studied. The 60 genotypes were grouped into 11 clusters in case of D2 analysis indicating that the genetic diversity and geographical diversity were not related. By Mahalanobi’s D2 statistic, it could be inferred that 2.5% span length, seed index, days to 50% flowering, micronaire, number of monopodia per plant and bundle strength contributed maximum towards genetic divergence. Based on intra-and intercluster distance among the groups, it is suggested to make crosses between the genotypes of cluster IX (HYPS 152) and cluster X (IH 65), between genotypes of cluster IX (HYPS 152) and cluster XI (L 389), between the genotypes of cluster VII (TCH 1705) and cluster XI (L 389), between the genotypes of cluster VIII (GISV 267) and cluster X (IH 65) after confirming their general combining ability. Principal component analysis identified seven principal components (PCs), which contributed 78.696 per cent of cumulative variance. The significant factors loaded in PC1 towards maximum genetic divergence were plant height, ginning out turn, lint yield per plant, number of bolls per plant, 2.5% span length, seed index, lint index, number of monopodia per plant, days to 50% flowering, seed cotton yield per plant, number of sympodia per plant and boll weight. 2D and 3D graphs showed wide divergence between GISV 267, MCU 5, HYPS 152, TCH 1741, CNH 120 M/B, LH 2256 and IH 65 signifying their usefulness in cotton breeding to develop high heterotic hybrids. The genotypes HYPS 152, GISV 267, MCU 5, L 389 and TCH 1741 showed maximum inter-cluster distance in Mahalanobi’s D2 analysis, principal component analysis and also have better per se performance in sympodia per plant, number of bolls per plant, boll weight, seed index, lint index and quality characters . So they can be exploited for the development of heterotic hybrids in future breeding programmes.
