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.

    STABILITY OF PHENOLOGICAL TRAITS, SEED YIELD AND QUALITY TRAITS IN ADVANCE BREEDING LINES OF CHICKPEA (Cicer arietinum L.)
    (guntur, 2022-11-11) PRASANTHI, GOLLA.; JAYALAKSHMI, V.
    The present investigation entitled “Stability of phenological traits, seed yield and quality traits in advance breeding lines of chickpea (Cicer arietinum L.)” was carried at Regional Agricultural Research Station, Nandyal, Andhra Pradesh, during rabi 2020-21 to study the nature and extent of genotype by environment interaction on phenological traits, seed yield and quality traits in chickpea and to investigate the stability and adaptability of the advance breeding lines of chickpea to various sowing windows of Andhra Pradesh. The study was taken up with 10 advance chickpea breeding lines and four released varieties planted in Randomized Block Design with three replications sown during October (E1), November (E2) and December (E3) representing various sowing windows adopted by farmers in Andhra Pradesh. The analysis of variance for nineteen characters viz., phenological traits like days to first flowering, days to 50% flowering, duration of vegetative phase, duration of flowering, duration of reproductive phase, days to maturity, leaf area index; yield attributing traits namely plant height, number of branches per plant, number of pods per plant, 100 seed weight, harvest index, seed yield; and quality traits like hydration capacity, swelling capacity, cooking time, protein content, zinc content and iron content recorded in three days of planting revealed significant variation among genotypes for all these traits, except for harvest index and protein content in E1 and days to first flowering and duration of vegetative phase in E3. Across various environments, advance breeding lines NBeG 690, NBeG 776 and NBeG 699 and released variety NBeG 119 exhibited high per se performance for phenological traits. Desi genotypes, NBeG 776, NBeG 779 and NBeG 690 were identified as promising for seed yield while in Kabuli genotypes, NBeG 789 is promising for harvest index, 100 seed weight and zinc content. NBeG 833 is a large seeded Kabuli with desirable quality traits like high protein content, hydration capacity and swelling capacity. Stability analysis as per Eberhart and Russel (1966) revealed highly significant genotype × environment interaction for days to 50% flowering, duration of flowering, leaf area index, number of branches per plant, number of pods per plant, harvest index, seed yield, hydration capacity, swelling capacity and iron content indicating a variable response of the genotypes to different dates of planting studied. Environments + (genotype x environments) were significant for all characters except for leaf area index, hydration capacity, swelling capacity, iron content and zinc content. The higher magnitude of mean sum of squares for environment (linear), compared to genotype × environment (linear) indicated that linear response of environment accounted for major part of the total variation for all the traits studied and might be responsible for high adaptation of the genotypes in relation to yield and other traits. Except for days to first flowering, cooking time, protein content and zinc content, the mean squares for pooled deviation (non-linear) were also significant indicating the importance of both linear and non-linear components in genotype × environment interaction observed for the traits in the present investigation. The E1 environment (October) was favourable for phenological traits, yield attributing traits and quality characters and E2 environment (November) was congenial for yield attributing traits. NBeG 47, NBeG 798 and NBeG 690 were stable genotypes with respect to the seed yield and considered to be promising genotypes for achieving high yields under variable environments. Genotypes NBeG 699, NBeG 440, NBeG 789, NBeG 833, NBeG 119 and KAK 2 were recommended for December planting (late planting) where as NBeG 779, NBeG 776, NBeG 452, NBeG 857 and NBeG 810 could be suggested for rich environment (October) for realizing enhanced yield. With respect quality traits, Kabuli genotypes NBeG 833, NBeG 789 and NBeG 440 had stable performance in all three sowing windows. The studies on variability revealed that there is sufficient genetic variability for leaf area index, number of branches per plant, number of pods per plant, plant height, harvest index, seed yield, 100 seed weight, hydration capacity, swelling capacity, cooking time and iron content in the genotypes and the traits exhibited high heritability and high to moderate genetic advance. Breeders can exploit the additive gene effects of these traits and transgressive segregation in breeding programmes would be fruitful for further genetic improvement in chickpea to develop high yielding chickpeas with matching phenology to various environments and with faster cooking time and high iron content. Seed yield exhibited positive and significant association with phenological traits viz., duration of flowering and duration of reproductive phase in all the three sowing windows. These key traits were influencing seed yield indirectly via other contributing characters like days to first flowering, duration of vegetative phase, leaf area index and days to maturity in October sowing and traits like plant height, number of branches per plant, number of pods per plant, 100 seed weight and also harvest index in late planting situation where crop is exposed to high temperature. Number of pods per plant though exhibited highly significant correlation with seed yield but had negative direct effect in October planting and high positive direct effect in December planting. Its significant correlation during October planting was established indirectly through duration of vegetative phase, days to maturity and leaf area index. Plant height with significant positive correlation with seed yield in December planting had high positive direct effect and also high indirect effect via duration of vegetative phase, duration of flowering, number of branches per plant. Swelling capacity, hydration capacity and cooking time are positively associated with 100 seed weight, but cooking time increased with the increase in seed weight. Strong correlations have been established between seed size and cooking time especially in Kabulis and therefore, special emphasis may be given for improving the seed size with less cooking time in extra-large seeded Kabulis.
