Abstract: Two separate experiments were carried out to evaluate early (experiment I) and mid (experiment II) maturing cultures/hybrids in Horticultural Research Farm, I.G.A.U., Raipur; during rabi 1998-99. Seven treatments of potato were included in the experiment conducted for early cultures/hybrids. In case of mid maturing cultures/hybrids, eight treatments were tested. All the treatments of both the experiments were replicated three times in a randomized block design. EXPERIMENT-I 1. Significantly higher yield of total tubers as well as marketable tubers \vere recorded in cultures/hybrids MS/90-542 (2 1 8.26 and 213.89 q/ha) and JW-96 ( 193.84 and 188.43 q/ha) as compared to other treatments tested in this study. 2. The- higher genotypic coefficient of variation was found for dry weight of roots per plant, yield (kg/plot), tuber bulking rate, fresh & dry weight of shoots per plant and tuber efficiency. 3. Tuber yield (kg/plot) showed positive significant correlation with number of shoots per plant, fresh weight of shoots, roots & tuber per plant, dry matter partitioning of roots and dry weight of shoots & tubers per plant. 4. In this study, the highest positive direct effect on tuber yield was observed through fresh weight of tubers per plant. However, per cent dry matter of tuber, number of leaves per plant, dry weight of roots per plant, tuber efficiency, fresh \veight of roots per plant and plant height also showed positive direct effect on tuber yield. On other hand, dry matter partitioning of tuber, dry weight of shoots per plant, dry matter partitioning of shoot and dry matter partitioning of root had negative direct effect on yield. EXPERIMENT-II 1. The highest yield of total tubers (257.08 q/ha) as well as marketable tubers (255.65 q/ha) were recorded in Kufri Badshah. However, no significant difference was observed among all the treatments for both the traits. 2. Dry weight of roots per plant, number of tubers per plant, fresh w eight of roots per plant, dry weight of shoots per plant, tuber bulking rate and number of leaves & stolens per plant had highest genotypic coefficient of variation. 3. Tuber yield (kg/plot) showed positive significant correlation with plant height, number of shoots, leaves & stolens per plant, dry weight of shoots, roots & tubers per plant, per cent dry matter of shoot and dry matter partitioning of shoot, root & tuber. 4. In this study, the highest positive direct effect on tuber yield was observed through dry weight of tubers per plant. However dry weight of shoots per plant, number of stolens per plant, number of tubers per plant and plant height also showed positive direct effect on tuber yield. On the other hand, fresh weight of shoots per plant, dry matter partitioning of tuber, per cent dry matter of tuber & shoot and tuber efficiency had negative direct effect on yield.
