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.

    MOLECULAR AND BIOCHEMICAL VARIABILITY OF CERTAIN BRINJAL GENOTYPES AGAINST SHOOT AND FRUIT BORER Leucinodes orbonalis (GUENEE) (LEPIDOPTERA: PYRALIDAE
    (ACHARYA N G RANGA AGRICULTURAL UNIVERSITY, GUNTUR, 2019) CHINNABBAI, CHETTUBATHINA; DAYAKAR, S
    The present investigations on “Molecular and biochemical variability of certain brinjal genotypes against shoot and fruit borer Leucinodes orbonalis (Guenee) (Lepidoptera: Pyralidae)” were carried out at college of Horticulture, Venkataramannagudem during both Rabi and Kharif seasons of 2016-17 and 2017-18, 2017-18 and 2018-19. Studies on screening of genotypes against shoot and fruit borer revealed that none of the genotypes showed complete resistance to shoot and fruit borer. Significantly lowest shoot infestation (9.01 %), as well as fruit infestation (12.73 %) were recorded with IC 136061.The highest infestation of shoot (34.99 %) and fruit (46.77 %) was recorded on Dommeru Local.The shoot infestation on remaining genotypes ranged from 11.34 % to 30.96 % and while the same for was 15.39 % to 43.79 %. Based on per cent fruit infestation genotypes fourteen genotypes viz., IC 136061 (12.73%), IC 136148 (15.39%), IC 135912 (16.08%), IC 136299 (16.14%), IC 136041(16.23%), IC 136296 (16.94%), IC 154517 (17.18%), A.Nidhi (17.18%), IC 203589 (17.23%), IC 213564 (17.46%), S.Pratibh (17.54%), IC 137751(19.06%), IC 144525 (19.42%) and IC 136231(19.89%) were categorized as moderately resistant due to low level of fruit infestation (11-20 %). In the remaining genotypes, twenty four were categorized as tolerant (20.00 to 30.00 % fruit infestation), twenty as susceptible (30.00 to 40.00 % fruit infestation) and five genotypes as highly susceptible (above 40.00 % fruit infestation). Genotype IC 136061 recorded highest fruit yield (1.484 kg plant-1) whereas VR 02 recorded lowest fruit yield (0.211 kg plant-1). The fruit yield in the remaining genotypes was ranged from 0.279 to 1.089 kg plant-1. IC 136148 (1.089 kg plant-1), A.Nidhi (1.070 kg plant-1) and IC 135912 (1.051 kg plant-1) were the other promising moderately resistant genotypes with low per cent shoot and fruit infestation and higher yield. xix The influence of physicomorphic and biochemical factors of shoot and fruit on the infestation of shoot and fruit borer revealed that per cent shoot infestation showed positive and highly significant correlation with shoot thickness (r = 0.9403), significantly high negative correlation with trichomes on leaf lamina (r = - 0.9755), significantly high negative correlation with trichomes on shoot (r = - 0.9484), non significant correlation with plant height (r = 0.1899), number of branches (r = 0.2395) and plant spread (r = 0.0557). The per cent fruit infestation showed positive correlation with fruit length (r = 0.9403), fruit diameter (r = 0.9755), pedicel length (r = 0.0009), number of branches (r = 0.1921), plant spread (r = 0.0379) while a significant and negative correlation with calyx length (r = - 0.3298). The per cent shoot infestation showed negative and highly significant correlation with phenol content in shoot (r = - 0.9587), highly significant and negative correlation with peroxidase content in shoot(r = - 0.9645), highly significant and negative correlation with PAL content in shoot (r = - 0.9692). Highly significant and positive correlation was observed between phenol content of shoot with peroxidase (r = 9937) and PAL (r = 0.9776). Peroxidase and PAL also showed highly significant and positive correlation (r = 0.9911). The per cent fruit infestation showed negative and highly significant correlation with phenol content in fruit (r = - 0.9717), highly significant and negative correlation with peroxidase content in fruit (r = - 0. 9586), highly significant and negative correlation with PAL content in fruit (r = - 0.9719). Significant and highly positive correlation was observed between phenol content of fruit with peroxidise (r = 0.9628) and PAL (r = 0.9758). Peroxidase and PAL also showed highly significant and positive correlation (r = 0.9643). The highest PIC was recorded in the SSR marker 133 (0.5911), while it was found to be lowest for the marker 120 (0.3504). SSR marker 139 recorded the highest heterozygosity of 0.5801 while the lowest in 133 (0.2217). All the genotypes under the present investigation were found to have unique allelic profiles with SSR loci.The ten selected SSR primers amplified alleles across the 60 genotypes and 3 checks with varying degrees of polymorphism. High level of polymorphism was observed with as many as 3 alleles per locus with 131,133 and 134 primers. The high level of polymorphism obtained with SSRs in the present study is consistent with their known characteristics that they were more variable and revealed greater diversity. The similarity index based on 10 SSR markers ranged from 0.200 to 1.000 Out of the seven modules evaluated against shoot and fruit borer, M1(moderately resistant genotype) found effective by recording low mean shoot infestation (11.76%), fruit infestation (15.05%) and was significantly superior over other modules. M7 (farmers practice) was the next best performer with 14.28% and 19.51% of shoot and fruit infestation respectively and was followed by M6 (17.69%, 31.34%), M5 (20.61% and 36.33%), M4 (23.24% and 39.75%), M3 (25.82% and 43.55%) and M2 (29.23%, 50.45%). In overall mean fruit infestation on weight basis also M1 showed significant superiority in performance over other modules. xx In terms of marketable fruit yield, M7 (farmers’ practice) effective as it recorded significantly highest marketable fruit yield (31692.27 kg ha-1) followed by M1 (31315.20 kg ha-1), M6 (25603.20 kg ha-1), M5 (23654.40 kg ha-1), M4 (19159.47 kg ha-1), M3 (17808.00 kg ha-1) and M2 (15052.80 kg ha-1). Observations on yield and cost economics of different IPM modules revealed that module M7 showed superiority over other modules in terms of yield ( 31692.27 kg ha-1), cost of production (Rs. 121750.00 ha-1) and gross returns (Rs.380307.20 ha-1). Module M1 produced 31315.20 kg ha-1 fruit yield, incurred low production cost (Rs.93137.00 ha-1) with gross returns of Rs. 375782.40 ha-1. The highest B: C ratio of 4.03:1 was registered with M1 and next best was M7 with 3.38:1. From the above investigation conducted for two years, it was concluded that selection of a moderately resistant variety and adoption of IPM methods are more effective in the management of shoot and fruit borer and was economically profitable.
