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.

    Genetic analysis of multiloculed pod character in sesame
    (Kerala Agricultural University, 1981) Sverup John; Gopinathan Nair, V; KAU
    Genetic analysis of he multiloculed condition in sesame was undertaken. Four multiloculed types isolated from a varietal collection and the four loculed type (Kayamkulam-1) were crossed in all passible combinations. The pod type in the hybrids was compared with that of the parents and conclusions drawn. The multiloculed condition was recessive to the four loculed condition. Estimation of the number of genes responsible for this character revealed the operation of two independent recessive genes symbolised as i ' and 'I/. Either of these in hoTiozygous condition produced multilocular expression. Presence of these two genes together in a genotype in the double recessive condition can produce a better expression of this character.

    Relative mutagenic effects of ionizing radiations and alkylating chemicals in rice
    (Kerala Agricultural University, 1981) Gopinathan Nair, V; KAU
    Studies were undertaken on the relative mutagenic effects of three ionizing radiations (X-rays, gamma rays, fast neutrons) and five alkylating chemicals (DES, EMS, MMS, NMH, MNNG) in rice. Observations on seed germination, seedling survival, seedling height, seed fertility and chlorophyll deficient chimeras were made in the IV^ generation. The M3 generation was grown as M, ear progenies. Chlorophyll mutation frequency, segregation percentage and mutant spectrum were estimated. The mutagenic effectiveness and efficiency were also worked out. Germination of seeds was not affected by radiations even at high doses. Chemical mutagens inhibited germination. Radiation induced lethality was manifested subsequent to germination, whereas lethality induced by chemical mutagens was expressed mostly through inhibition of germination. Seedling height was reduced fay mutagen treatments • Gamma rays and NMH were more effective in this respect Radiations induced high degreesof sterility than chemical mutagens. Fast neutrons induced more sterility per unit dose than sparsely ionizing radiations. Chlorophyll deficient sectors were more frequent in M; plants after treatment with NMH and EMS. NMH, however, was more effective than EMS in this respect. Mutation frequency estimated on M,ear basis was as efficient as that on M.J plant basis because the study was confined to pre-formed ears. Gamma rays fast neutrons, EMS and NMH had induced high frequencies of chlorophyll mutations. Per unit dose, fast neutrons was more effective than gamma rays and atequimolar concentrations NMH was more effective than EMS. The mean segregation percentages were higher after treatment with radiation than with chemical mutagens. The spectra of mutants differed between radiations and chemical mutagens. Albina was the most frequent type following irradiation. In chemical mutagen treatments, the frequency of albina was low and that of viridis was high. Radiations were more effective than chemical mutagens• Mutagenic effectiveness decreased with increase in doses of mutagens. This was due to the failure of mutation frequency to increase proportinately with increase in mutagen doses. Mutagenic efficiency was higher for radiations when estimated on the basis of lethality and injury whereas, based on sterility, chemical mutagens were more efficient. Mutagenic efficiency also decreased with increase in doses of mutagens. The most effective as weli as efficient radiation was fast neutrons Among chemical mutagens the most effective was NMH whereas the most efficient was EMS.

    Inheritance of fruit colour in normal and irradiated progenies of brinjal
    (Kerala Agricultural University, 1980) Gopimony, R; Mary K George; Gopinathan Nair, V; KAU
    The inheritance of fruit colour in brinja! (Solarium metongena) was studied by analysing the progeny belonging to the F, M2, FjM^ and F3M generations resulting from a cross between varieties insanum and purple giant followed by gamma irradiation. The F0 phenotypic frequencies fitted very well with the dihybrid ratio indicating that the fruit colour is governed by two independently inherited genes. Three colour mutants, namely, purple, mottled green and white were induced in the F]MI generation by the irradiation. The appearance of these mutants is explained as due to independent mutations at either or both of the two genetic loci. The colour pattern in the F3M., progenies derived from the F, Mj mutants substantiates the two gene mechanism for the inheritance of fruit colour. The genotypes for the different colour types in the FL, F, and FlMl mutants have been indicated and discussed.

    Mutual dependance of m1 fertility and m2 mutations in rice
    (Kerala Agricultural University, 1982) Gopinathan Nair, V; KAU
    The mutual dependance of Mj fertility and Ma mutations in rice was studied after treatment with gamma rays and EMS. The frequency of chlorophyll mutations increased with decrease in seed fertility when M, ears were selected at random. However, at the lowest fertility class the mutation frequency was low. This reduction is attributed to the elimination of mutants in the high sterility class. The mutation yield can therefore be significantly enhanced by selecting Mj ears of low fertility. The segregation ratio of mutants increased as fertility decreased. Mutation spectrum was however not influenced by IV!1 fertility. This makes selection for fertility quite ineffective in altering the mutation spectrum.
