Abstract:
An investigation entitled "Genetic Variability Studies in Tamarind (Tamarindus indica L.)" was conducted at Main Garden, Department of Horticulture, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola during the year 2018-20 with objectives to estimate the extent of genotypic and phenotypic variability among tamarind genotypes. To study genotypic, phenotypic and environmental correlation for yield and yield contributing characters of tamarind genotypes. The experimental evidences point out that, analysis of variance revealed that highly significant difference among the genotypes for all the traits studied. The mean performance of 22 genotypes showed wide variation. The study on genetic variability parameters observed high PCV and GCV estimates for the character rag weight, Yield/plant, stem girth, pulp weight, pod weight, shell weight, seed weight, inflorescence length, number of pod/kg, non-reducing sugar, number of seed/pod, seed: pulp ratio. High heritability accompanied with high expected genetic advance was recorded for length of pod, pod width, pod weight, no. of pods/kg, shell weight, rag weight, pulp weight, seed weight, pulp: shell ratio, seed: pulp ratio, no. of seed/pod, inflorescence length, stem girth, non-reducing sugar, yield per plant (kg). It is clear that, these traits were highly heritable showing the presence of additive gene action. Thus, it is indicating better scope for improvement of these traits by an effective selection programme. On the basis of yield and yield contributing characters the genotype viz., MGNT7, MGNT5, MGT1/1 and AGT-3 were found promising for future improvement programme. Hence, these genotypes may be given consideration while formulating selection indices for the improvement of yield and pod qualities of tamarind. Qualitative parameters revealed a wide range of variation for the characters under investigation.
