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 STUDIES IN COTTON (Gossypium hirsutum L.) FOR YIELD AND YIELD COMPONENTS
    (Acharya N.G. Ranga Agricultural University, 2017) AZMI SHAIK, DADA; GOVINDA RAO, B
    The present investigation was carried out during kharif, 2016-17 at Regional Agricultural Research Station, Lam farm, Guntur, Andhra Pradesh to characterize 40 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 fifteen yield component traits with seed cotton yield per plant 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), ginning out-turn (%), seed index (g), lint index (g), 2.5% span length (mm), micronaire (10- 6 g/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. High heritability coupled with moderate genetic advance was observed in case of micronaire, 2.5% span length and bundle strength revealing the role of additive and non additive gene action. The other traits viz., number of monopodia per plant, number of sympodia per plant, number of bolls per plant and boll weight showed moderate heritability and moderate genetic advance. This indicates the presence of additive and non-additive gene action and further improvement of these traits would be possible through heterosis breeding rather than simple selection. Correlation study indicated that plant height, days to 50% flowering, number of sympodia per plant, number of bolls per plant, boll weight, ginning out turn, seed index, lint index, micronaire, bundle strength, uniformity ratio and lint yield per plant had positive significant association with seed cotton yield per plant. Path coefficient analysis revealed that days to 50% flowering, bundle strength, number of bolls per plant, number of sympodia per plant, plant height and number of monopodia per plant exerted highest positive direct effect on seed cotton yield per plant followed by, ginning out-turn, seed index, lint index and micronaire. 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 40 genotypes studied. The 40 genotypes were grouped into seven clusters by using Tocher’s method in D 2 analysis which indicated that the genetic diversity and geographical diversity were not related. By Mahalanobis’ D 2 statistic, it could be inferred that seed index, days to 50% flowering, boll weight, 2.5% span length and micronaire contributed maximum towards genetic divergence. Based on intra-and inter-cluster distance among the groups, it is suggested to make crosses between the genotypes of cluster VI (ARBH 1402) and cluster VII (HYPS 152), between genotypes of cluster I (SSGR 105) and cluster VIII (L 788), between the genotypes of cluster I (SSGR 105) and cluster IV (L 799), between the genotypes of cluster V (GJHV 497) and cluster VIII (L 788) after confirming their general combining ability. Principal component analysis identified six principal components (PCs) which contributed 81.99 per cent of cumulative variance. The significant factors loaded in PC1 towards maximum genetic divergence were seed cotton yield per plant, bundle strength, lint index, micronaire, number of bolls per plant, number of sympodia per plant, plant height and uniformity ratio. The 2D and 3D graphs showed wide divergence among the F-2522, TCH-1716, ARBH-1501, HS-296, CPD-1502 and GJHV-517 signifying their usefulness in cotton breeding to develop high heterotic hybrids. The fore mentioned six genotypes showed maximum inter-cluster distance in Mahalanobis’D 2 analysis, principal component analysis and cluster analysis and also for better performance for number sympodia per plant, number of bolls per plant, boll weight, seed index, lint index and quality characters. So they could be exploited for the development of heterotic hybrids in future breeding programmes.
