Variability, heritability, genetic gain, genetic advance and correlation in morphological and seed characteristics in Toona ciliata


Author(s): Thiyam Jefferson Singh, Tara Gupta and RK Gupta

Abstract: Toona ciliata is an important timber species of India which is found in H.P. as natural populations, mostly along the cultivated fields and roads. In fact this is a multipurpose tree species of tropical and subtropical areas. Seeds of Toona ciliata were collected from ten locations and morpholological chraacters study in three locations to study the extent and pattern of variation with respect to various traits. Variability and genetic estimates for number of flower and inflorescence length showed low genotypic coefficient of variability, low to moderate genetic gain and high heritability; h=0.41 and 0.62 respectively for both the characters. It indicates that these traits are under additive genetic control and may be considered effective for selection. Positive and significant correlation was observed between flower number and inflorescence length (r = 0.94) and negative correlation was observed between leaflet number and fruit setting (r = -0.24).
