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.

    STABILITY ANALYSIS OF POD YIELD AND ITS IMPORTANT TRAITS IN SPANISH RDNCH GROUNDNUT {Jlrachishypogaea L) GENOTYPES
    (University of Agricultural Sciences GKVK, Banglore, 2007-01-04) KALMESHWER GOUDA, PATIL; P. V. KENCHANA, GOWDA
    An experiment was carried out involving thirteen genotypes and four check varieties during kharif 2003 at six different locations to know the magnitude of variability present and to assess the stability of genotypes for productivity traits. The genotypes were also assessed for change in the nature of inter-relationships and path effects of different characters towards pod yield. Mean performance of genotypes indicated that Nippani was the most favourable environment for better expression of most of the characters. Analysis of variance revealed significant differences among most of the characters suggesting a high degree of variability among the genotypes tested. Genetic variability analysis revealed pod yield per plant and hundred kernel weight had higher variability, heritability and expected GAM as compared to other traits. The pooled analysis of variance revealed significant differences among the genotypes and environments for most of the characters indicating the genotypes and environments tested are diverse in nature. Genotype x environment interaction was significant for all the traits suggesting genotypes interacted significantly with the environments. While, genotype x environment (linear) interaction was significant for plant height, pod yield per plant and shellirg per cent indicating genotypes responded linearly to the changing environment. The non-linear component (pooled deviation) was highly significant for all the traits indicating this part of the variation in terms of performance of the genotypes is unpredictable. On the basis of stability parameters, Dh-104 and Mutant III were promising genotypes for majority of characters with higher mean performance across the six environments. The association analysis revealed that pod yield per plant exhibited significant positive association with number of pods, shelling per cent and SMK per cent at five locations and path analysis indicated that number of pods, shelling per cent and SMK per cent exerted high direct effect each in three locations.

    MOLECULAR CHARACTERIZATION, INHERITANCE AND VALIDATION OF MARKERS LINKED TO AROMA IN RICE (Oryza sativa L.) UNDER AEROBIC CONDITION
    (University of Agricultural Sciences GKVK, Bangalore, 2008-06-15) KALMESHWER GOUDA, PATIL; KULKARNI, R. S.
    Rice (Oryza sativa L.) has a renowned relationship with the humans since ages. India produces some of the best quality aromatic rices in the world, which includes Basmati type and non-Basmati, short and medium grained type. Most of the work on aromatic rice is concentrated mainly on basmati rice while, very limited organized efforts have been made on the latter. Characterization of 24 aromatic rice genotypes revealed, none of the genotypes were superior in respect of all the traits studied. Nevertheless, the genotype IET 18981 exhibited higher grain yield per plant while, Kalanamak and K 44-1 were rich in iron and zinc content. Correlation studies indicated highly significant and positive correlation of grain yield with number of productive tillers per plant and number of tillers per plant. The inter-cluster distance was not consistent with the geographic distribution of varieties. The varieties belonging to diverse ecological regions clustered together whereas, genotypes of the same region have entered widely into separate groups. Contribution of each character towards genetic divergence indicated that grain yield per plant contributed maximum towards the genetic divergence. The results of molecular characterization revealed presence of variation between basmati and non-Basmati genotypes for aroma. Most of the Basmati genotypes were grouped to one cluster while, all the local non-basmati genotypes were grouped to another cluster. The results of evaluation of F2 populations of three crosses developed viz., IRRI 38 x Jeerige sanna, BI 33 x Jeerige sanna and Azucena x Moro mutant, indicated higher PCV, GCV, heritability and genetic advance as per cent of mean for most of the characters. The results of studies on inheritance pattern of aroma in all the three crosses indicated that, the trait is governed by single recessive gene (3 non-aromatic: 1 aromatic). The results of single-marker analysis revealed the association of OPC 07 and RM 264 markers with aroma which explained 34 and 44 per cent of variation in the respectively.
