University of Agricultural Sciences, Bengaluru

University of Agricultural Sciences Bangalore, a premier institution of agricultural education and research in the country, began as a small agricultural research farm in 1899 on 30 acres of land donated by Her Excellency Maharani Kempa Nanjammanni Vani Vilasa Sannidhiyavaru, the Regent of Mysore and appointed Dr. Lehmann, German Scientist to initiate research on soil crop response with a Laboratory in the Directorate of Agriculture. Later under the initiative of the Dewan of Mysore Sir M. Vishweshwaraiah, the Mysore Agriculture Residential School was established in 1913 at Hebbal which offered Licentiate in Agriculture and later offered a diploma programme in agriculture during 1920. The School was upgraded to Agriculture Collegein 1946 which offered four year degree programs in Agriculture. The Government of Mysore headed by Sri. S. Nijalingappa, the then Chief Minister, established the University of Agricultural Sciences on the pattern of Land Grant College system of USA and the University of Agricultural Sciences Act No. 22 was passed in Legislative Assembly in 1963. Dr. Zakir Hussain, the Vice President of India inaugurated the University on 21st August 1964.

    Development of Dual Resistance to Tomato Leaf Curl Virus and its Vector Whitefly (Bemisia tabaci) using Lycopersicon hirsutum (LA1777) Introgressed Lines in Tomato (Lycopersicon esculentum)

    Tomato Leaf Curl Virus (ToLCV) is one of the most important and major constraints in tomato cultivation which is solely transmitted by whitefly. Hence it is appropriate to develop varieties that show resistance to both virus and whitefly infestation. In the present study, Lycopersicon hirsutum introgressed Nearisogenic Lines and Back Cross Recombinant Inbred Lines were screened for whitefly resistance, ToLCV resistance, yield and fruit quality parameters. A total of eight lines (LA3913, LA3914, LA3916, LA3921, LA3942, LA3946, LA3948 and LA3978) were selected based on high whitefly resistance. These lines were crossed to ToLCV resistant varieties -Nandi, Sankranti and Vybhav for combining vector and virus resistances. Three hybrids viz., Sankranti x LA3916, Nandi x LA3948 and Sankranti x LA3948 were found to have similar yield potential as that of standard check Vybhav and were also resistant to both ToLCV and whitefly. With regard to fruit quality parameters, Sankranti x LA3916 possessed high acidity values whereas Nandi x LA3948 and Sankranti x LA3948 have exhibited lower acidity values with high ratio of total soluble solids to acidity which is good for processing industry. The combining ability analysis revealed that the additive gene action is predominantly governing most of the traits suggesting choice of combination breeding with pedigree selection to identifying transgressive segregants. The best hybrid Nandi x LA3948 was forwarded to F2 generation and six F2 plants were selected based on their yield potential. Their yield levels were on par with the standard check Vybhav but significantly higher than Nandi and Sankranti. The SCAR markers were developed based on sequence information of RFLP markers mapped in the Lycopersicon hirsutum introgressed regions specific to the selected whitefly resistant lines. Majority of these markers showed monomorphism in the respective lines except SCTG554 in the line LA3921. The RFLP marker, TG105 linked to ToLCV resistance was also converted to SCAR and it differentiated ToLCV resistant and susceptible varieties.
