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 DIVERGENCE OF ELITE PARENTAL LINES USEFUL FOR DEVELOPMENT OF RICE HYBRIDS AND STUDY OF HETEROSIS OF SOME RESULTANT HYBRIDS IN RICE (Oryza sativa L.)
    (guntur, 2022-08-17) ANAND VARDHAN, C.; SUBBA RAO, M.
    The present investigation was undertaken in rice during kharif 2020- 21 to study the genetic variability, heritability, genetic advance, genetic divergence, character association, path analysis, identification of maintainer / restorer reaction of parental lines, heterobeltiosis and standard heterosis of hybrids for yield and yield components of promising hybrids. The present investigation was carried out at Regional Agricultural Research station (RARS), Nandyal with 8 CMS lines, 27 male parental lines and 38 hybrids of rice (Oryza sativa L.) to elicit information on the nature and extent of variability, heritability, genetic advance, character association, the magnitude of direct and indirect effects of yield components on yield and genetic divergence based on 10 characters viz., days to 50% flowering, days to maturity, plant height (cm), productive tillers plant-1, panicle length (cm), total grains panicle-1, filled grains panicle-1, spikelet fertility (%), test weight (g) and grain yield plant-1 (g). High PCV, high GCV and high heritability coupled with high genetic advance were observed for grain yield plant-1 (g), filled grains panicle-1 and spikelet fertility per cent indicating the presence of broader variability for these traits in the genotypes studied. xv The results of Mahalanobios D2 analysis indicated the presence of considerable genetic divergence among 37 genotypes studied. The genotypes were grouped into seven clusters. Of the 10 characters studied, grain yield plant-1, total grains panicle-1, days to 50% flowering, test weight and plant height contributed maximum towards divergence. Correlation study indicated positive significant association of days to 50% flowering, days to maturity, days to maturity, productive tillers plant-1, panicle length, total grains panicle-1, filled grains panicle-1, and test weight at both genotypic and phenotypic levels with grain yield plant-1. So, increase in grain yield plant-1 can be attained by improvement of the above-mentioned characters in breeding programme. The path analysis indicated positive significant association and high positive direct effect for days to 50% flowering, plant height, productive tillers plant-1, total grains panicle-1, spikelet fertility per cent and test weight on the grain yield plant-1 at genotypic and phenotypic level and filled grains panicle-1 at phenotypic level. Floral studies indicated maximum out crossing per cent in CMS line APMS 6A followed by IR 58025A. This is attributed to floral traits viz. panicle exertion per cent and angle of floret opening. Eight superior WA based CMS lines viz., CMS 16A, CMS 23A, APMS 10A, IR 68888A, IR 68897A, IR 58025A, IR79156A and APMS 6A were crossed with 27 elite male lines during kharif, 2020-21. Pollen and spikelet sterility / fertility for 38 specific crosses were studied and of all 38 crosses studied and 14 hybrids showed maintainer reaction (75% spikelet fertility) and they are they are designated as partial restorers, 5 (50 – 75% spikelet fertility) showed partial fertility and 7 hybrids displayed partial fertility (< 45% spikelet fertility) and they are designated as partial maintainers. The male parents which showed maintainers reaction can be further studied for floral traits and best lines can be backcrossed for development of new CMS lines. The male parents which have showed fertility restoration can be further used for crossing with different CMS lines for development of new heterotic hybrid combinations. The hybrids NDLRH 244, NDLRH 304 and NDLRH 293 exhibited significant standard heterosis over the two check varieties BPT 5204 and MTU 1010 with desirable traits like days to 50% flowering, day to maturity, productive tillers plant-1, total grains panicle-1, filled grains panicle-1 and grain yield plant-1. These hybrids may be thoroughly tested over large number of locations for further confirmation before they are exploited commercially.
