Abstract:
Field experiment was conducted during 2015-16 at Horticultural College and Research Institute, Dr. Y. S. R. Horticultural University, Venkataramannagudem, West Godavari district. The objective of the experiment was to determine and evaluate the growth and yield performance of orange flesh sweet potato genotypes under coastal Andhra Pradesh condition. Treatments comprised of 25 different genotypes. The experiment was laid out in randomized complete block design with three replications. The performance evaluation of different genotypes was assessed by analyzing data on vegetative growth and yield. Results demonstrated that there is significant difference on performance of different orange flesh sweet potato genotypes. Based on the mean performance, the genotype VRSP-3 found to be elite for length of leaf lobe whereas for the width of leaf lobe SWA-2, ACC-5 for petiole length, VRSP-13 for leaf area, VRSP-12 for total leaf dry weight, for chlorophyll content VRSP-2, VRSP-4 for length of vine, for internodal length Kiran, VRSP-13 for number of branches per plant, for fresh weight of whole plant, dry weight of whole plant and fresh weight of root VRSP-12, for dry weight of root VRSP-9, for number of root tubers per plant VRSP-13, for root tuber length VRSP-1, for root tuber girth VRSP-3, for root tuber yield per plant VRSP-12, VRSP-13, VRSP-3, VRSP-1, VRSP-5 and VRSP-9 and for root tuber yield per hectare VRSP-3, VRSP-8, VRSP-13, VRSP-1 and VRSP-12 were found to be elite among all the 25 genotypes.
