Abstract:

A study was conducted at Horticultural College and Research Institute, Venkataramannagudem, W.G Dist during kharif season of 2010-11 to differentiate morphological marker characters between male and female plants and these characters will be helpful to identify the male plants at an early stage and to plant new female plants in that space. The male and female plants were, observed for distinct morphological characters. The differences were evaluated between sex forms and the results were analysed through two sample t-test. Plant height, internodal length, leaf margins, number of lobes, leaf shapes and days to appearance of first male and female flowers were found to be significant. The plant height of male and female plants measured at regular intervals revealed that the growth of male plants was faster when compared to female plants. Similarly the internodal length was more in male plants. The number of lobes in leaf was more in female plants. Male flower appear earlier than female flowers. The leaf shape of female plant was mostly mapple like where that of male plant was cordate and mapple. The characters like leaf length, leaf width, petiole length, tendril length, leaf area were found to be non significant. The lobe tip of female leaves was 80 % acuminate where as in male leaves the lobe tips were 50 % acute and 50% acuminate The marker characters giving distinct difference between male and female sex forms were leaf margin, leaf shape and number of lobes.
