Kerala Agricultural University, Thrissur

The history of agricultural education in Kerala can be traced back to the year 1896 when a scheme was evolved in the erstwhile Travancore State to train a few young men in scientific agriculture at the Demonstration Farm, Karamana, Thiruvananthapuram, presently, the Cropping Systems Research Centre under Kerala Agricultural University. Agriculture was introduced as an optional subject in the middle school classes in the State in 1922 when an Agricultural Middle School was started at Aluva, Ernakulam District. The popularity and usefulness of this school led to the starting of similar institutions at Kottarakkara and Konni in 1928 and 1931 respectively. Agriculture was later introduced as an optional subject for Intermediate Course in 1953. In 1955, the erstwhile Government of Travancore-Cochin started the Agricultural College and Research Institute at Vellayani, Thiruvananthapuram and the College of Veterinary and Animal Sciences at Mannuthy, Thrissur for imparting higher education in agricultural and veterinary sciences, respectively. These institutions were brought under the direct administrative control of the Department of Agriculture and the Department of Animal Husbandry, respectively. With the formation of Kerala State in 1956, these two colleges were affiliated to the University of Kerala. The post-graduate programmes leading to M.Sc. (Ag), M.V.Sc. and Ph.D. degrees were started in 1961, 1962 and 1965 respectively. On the recommendation of the Second National Education Commission (1964-66) headed by Dr. D.S. Kothari, the then Chairman of the University Grants Commission, one Agricultural University in each State was established. The State Agricultural Universities (SAUs) were established in India as an integral part of the National Agricultural Research System to give the much needed impetus to Agriculture Education and Research in the Country. As a result the Kerala Agricultural University (KAU) was established on 24th February 1971 by virtue of the Act 33 of 1971 and started functioning on 1st February 1972. The Kerala Agricultural University is the 15th in the series of the SAUs. In accordance with the provisions of KAU Act of 1971, the Agricultural College and Research Institute at Vellayani, and the College of Veterinary and Animal Sciences, Mannuthy, were brought under the Kerala Agricultural University. In addition, twenty one agricultural and animal husbandry research stations were also transferred to the KAU for taking up research and extension programmes on various crops, animals, birds, etc. During 2011, Kerala Agricultural University was trifurcated into Kerala Veterinary and Animal Sciences University (KVASU), Kerala University of Fisheries and Ocean Studies (KUFOS) and Kerala Agricultural University (KAU). Now the University has seven colleges (four Agriculture, one Agricultural Engineering, one Forestry, one Co-operation Banking & Management), six RARSs, seven KVKs, 15 Research Stations and 16 Research and Extension Units under the faculties of Agriculture, Agricultural Engineering and Forestry. In addition, one Academy on Climate Change Adaptation and one Institute of Agricultural Technology offering M.Sc. (Integrated) Climate Change Adaptation and Diploma in Agricultural Sciences respectively are also functioning in Kerala Agricultural University.

    Fruit component and seedling progeny analysis of komadan coconut types
    (Department of Plant Breeding, College of Agriculture, Vellayani, 1992) Manju, P; KAU; Gopimony, R
    The present study was undertaken with a view to unravel the genetic status of a coconut type, Komadan, popular in the Central Travancore region of Kerala, in relation to its origin by comparing its three generations with WCT and NCD through fruit component and seedling progeny analysis. The study revealed that the Komadan types showed significant superiority for majority of the mother palm characters especially number of bunches and spadices and number of nuts per palm per year. Number of nuts per palm per year and number of female flowers per bunch had high heritability combined with moderate to high genetic advance indicating the predominance of additive genes. Among the Komadan palms, 33 per cent were of self pollinating nature thereby occupying a position in between WCT and NCD regarding pollination system. All the Komadan palms had nuts of different shades of brown while 70 per cent of WCT palm had nuts of green shade and NCD palms had varying shades of green, olive and brown nuts indicating the distinction of Komadan as a separate group. Komadan types were superior to WCT in all seednut characters except polar diameter of nut, oil content, thickness of husk and husk/nut ratio. It behaved as a distinct type regarding thickness of meat. One or the other of the Komadan generations was found to be on par with NCD for majority of the seednut characters. Komadan types occupied an area midway between NCD and WCT based on Niu kafa-Niu vai Introgression hypothesis with a clear progression through generations towards better weight of unhusked nut. Inbreeding depression was noticed in WCT and NCD as indicated by significant reduction in embryo and kernel weight in selfed nuts compared to open pollinated nuts. In Komadan there was no inbreeding depression indicating a high degree of homozygosity. The seednuts of Komadan types showed early germination compared to WCT and NCD. Regarding seedling characters, Komadan behaved as a distinct type for total leaf area over both WCT and NCD. Number of seedlings with split leaves was also more in Komadan. This type was superior to WCT for seedling vigour index also. Estimation of prepotency based on recovery of quality seedlings showed that 40 to 60 per cent of Komadan palms were prepotent where as the same in WCT and NCD were only about 20 per cent. Analysis of petiole colour of seedlings showed that 71 to 82 per cent of seedlings among the three Komadan generations showed moderates brown colour (bronze) ; 97 per cent of WCT seedlings had different shades of green and wider variations in petiole colour were noticed in NCD seedlings. It can be concluded that the Komadan type maintained its genetic identity over generations with respect to economically important characters viz. Kernel, copra, and oil content and also in the recovery of quality seedlings which inturn reflects its prepotent nature. The collection and maintenance of typical komadan germplasm through inter se crossing and development of isolated seed gardens for large scale production of komadan seedlings are suggested as future line of work.
