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.

    STUDY OF GENE ACTION FOR GRAIN QUALITY, PHYSIOLOGICAL AND YIELD TRAITS IN RICE (Ovza sativa L.)
    (Acharya N G Ranga Agricultural University, Guntur, 2009) ADILAKSHMI, D; RAGHAVA REDDY, p
    ABSTRACT In 21 cr0sse.s obtained from seven parent diallel, nature of gene action and extent of heterosis were studied for six yield components, five physiological and eleven grain qualit) characters along with yield during rahi 2006-07, kharif2007 - . . and rabi 2007 -08. Gene effects were estimated from six generations of two crosses Genetic parameters like GCV, PCV, heritability and genetic advance were estimated. Combining ability analysis, generation mean analysis, character association, path coefficient analysis and selection indices were also carried out. The phenotypic coefficient of variation was higher than the genotypic coefficient of variation. indicating the profound influence of environment on the expression of characters. The estimates of genetic parameters exhibited higher heritability and genetic advance for all the characters except for ear bearing tillerslplant and panicle length. Thus improvement can be sought by straight selection for these characters. . '.. ' Gca effects were greater than sca effects, non-additive gene action primarily governed almost all the yield components, physiological and quality characters as the sca variance is greater than the gca variance. The estimates of heterosis and heterobeltiosis were variable among crosses in desirable direction and some of them turned out to be best specific crosses. Samba mahsurilprabhat (Ear bearing tillers), samba mahsuril Jagtial samba (1000 grain weight) Samba mahsuri/ Nellore mahsuri (harvest index), Nellore mahsuril Viljetha (head rice recovery). Indra/vi.ietha (LIB ratio) Indralvijetha and Samba mahsurit Polasa prabha (kernel elongation ratio), Samba Mahsurillndra (amylose content), Samba mahsuril lndra (protein content) and IndraIPrabhat ( Iron and Zinc contents) were best specific crosses and exhibited maximum heterosis. These can be used in recombination breeding to spot true breeding progenies. - . Among the parents, Prabhat was good general combiners for most of the yield contributing characters viz.. panicle length. number of seeds per panicle and 1000 grain weight and Prabhat for ear bearing tillerslplant. Samba mahsuri for harvest index and lndra for biological yield were good general combiners among physiological traits. lndra contributed maximum for hulling whereas samba mahsuri contributed highest towards milling trait and important cooking quality trait elongation ratio. Among nutritional quality traits Samba mahsuri and Nellore rnahsuri contributed maxim~rm with intermediate gelatinization temperature and amylose content whereas Nellore mahsuri for protein content. I Additive variance was available for selection in the crosses for Ear bearing tillers (Samba mahsurit Polasa prabha), head rice recovery (Samba mahsuri1Polasa prabha), kernel elongation ratio (Samba mahsuril Nellore mahsuri), Specific leaf weight (Samba mahsuril Polasa prabha and Samba mahsuril Nellore mahsuri) protein content (Samba mahsurimellore mahsuri and Samba mahsuri/Polasa prabha) and grain yield (Samba mahsuri/Polasa prabha' and Sarnaba mahsuri/ Nellore mahsuri). -. - -- For character association Ear bearing tillers, panicle length and 1000 grain weight among the yield component; harvest index, biological yield and flag leaf lU content among physiological traits exhibited positive significant correlation with yield. I J~~lling percent, milling percent and protein content exhibited positive association with yield in case of quality traits. Protein content exhibited negative association with elongation ratio suggesting that, superfine rices are to be upgraded regarding protein content. All the characters under study except days to 50% flowering, panicle length and specific leaf weight exhibited positive direct effect on yield. Keeping in view the significant association along with positive direct effects; Ear bearing tillers, 1000 grain weight, harvest index, biological yield, flag leaf N content, hulling percent, milling percent and protein content can be considered for isolating good genotypes. The association of flag leaf Nitrogen content with days to 59% flowering, plant height, ear bearing tillers, panicle length, number of seeds per panicle, 1000 grain weight. biological yield, hulling percent, milling percent, LIB ratio, protein content, Zinc and yield per plant indicates its significance.
