Abstract

Sweet potato (Ipomoea batatas (L.) Lam.) is one of the important tuber crops of tropical and sub-tropical regions of the world. Studies on morphological characterization of 51 sweet potato genotypes were carried out at Shalmala Vegetable Research Centre, Regional Horticultural Research and Extension Centre (RHREC), Dharwad (University of Horticultural Sciences, Bagalkot) during rabi, 2019-20 and 2020-21. Aim of study is to know the morphological variations in collected genotypes. The sweet potato genotypes showed wide morphological variability for plant type, inter-nodal length, leaf size, mature leaf shape, petiole length, tuber shape, tuber skin color and tuber flesh color. The observed morphological characters variations were used to discriminate genotypes into different groups. The morphological study helps for identifying superior genotypes for variety development.

Keywords

Sweet potato; Morphology; Genotypes.

Conclusion

Significant morphological variation were observed among the 51 sweet potato genotypes studied. Majority of genotypes having semi erect plant (30 genotypes), short inter-nodal length (43 genotypes), medium size leaf (39 genotypes), very deep lobed leaf (29 genotypes) and short petiole length (43 genotypes). Similarly tuber shape, tuber skin colour and flesh colour showed greater variability. The study reveals that the morphological characters used in this study would effectively discriminate the different genotypes. The evaluation of morphological characters of distinct genotypes helps for identifying superior genotypes for crop improvement.
