Bhadra (MO 4) A high yielding dwarf rice variety for Kuttanad
(Kerala Agricultural University, 1981) Nair, N R; Nair, S S; Rema Bai, N
IR-8 and Ptb-20 were crossed in 1967-68 at Rice Research Station Moncompu in order to evolve a high yielding variety possessing good grain quality attributes. Culture M-11-57-5-1 is a derivative of the above cross. It has recorded significantly higher yield than the popular high yielding varieties Jaya and Bharathy in the experiments in the Research Station, in State Seed Farm and in cultivators' fields It was also superior to two other varieties Sabari and Aswathi under Kuttanad conditions. Further, this possesses additional attributes like good tolerance to Brown plant hopper and desirable grain qualities. This culture was released by the variety Release Committee of the State as a 'variety under the name "Bhadra" (M 04).
Genetic variability and correlation in short duration rice cultivars
(Kerala Agricultural University, 1994) Ahmed Regina; Rema Bai, N; Devika, R; Joseph, C A
In order to understand the nature and extent of variability and association of various quantitative characters with grain yield, a field experiment was conducted with 45 short duration rice genotypes at the Rice Research Station, Moncompu. The environmental influence on the different traits was evident from the phenotypic coefficient of variability being higher than the genotypic coefficient of variability. Characters such as plant height, flag leaf area, panicle exsertion, number of grains per panicle and grain yield exhibited moderate to high heritability and genetic advance. Grain yield was found to be positively correlated both at genotypic and phenotypic level with number of productive tiller's per hill, plant height, flag leaf area, panicle length anil number of grains per panicle.
Pavithra (MO 13) and Panchami (MO 14): Two gall midge resistant varieties of rice

Studies on intervarietal hybrids of tomato
(Division of Agricultural Botany, College of Agriculture, Vellayani, 1975) Rema Bai, N; Mary K George
The present investigations were carried out in College of Agriculture, Vellayani during the year 1974-75. Five varieties of Lycopersion esculentum viz., YRFN-3, Mech9, VF36, Walter and Local were utilised for intercrossing. Investigations on the quantitative and qualitative characters, heterosis, hybrid sterility and sucrose content of the parents and hybrids were undertaken. Though the hybridisation work was done in all combinations, there was fruit setting only in fourteen crosses. YRFN-3 as male parent failed to cross with any other varieties except with Walter. In this case though fruit setting was occurred, seeds obtained were not viable. YRFN-3 as female parent also failed to cross with any other varieties except with Local.
