ABSTRACT
An experiment was conducted to estimate heterosis and combining ability for tuber yield and its components under early harvest crop (75 day after planting) and medium harvest crop (90 day after planting) of potato in 32 crosses using Line × Tester (8 × 4) matting design. The female parents, Khfri Pushkar, Kufri Jyoti and Pollinators, Kufri Chipsona 2 was found good combiners at both the harvest conditions. The hybrids, Kufri Jyoti × Kufri Chipsona 2 had the highest per se performance with significant positive relative heterosis and positive SCA effects while, hybrid Kufri Laukar × Kufri Chipsona 1 and MS/95-117 × TPS 13 had the highest per se performance and significant positive SCA effects for tuber yield along with significant heterobeltiosis in 75 days harvest condition. The hybrid Kufri Pushkar × Kufri Chipsona 1 had the highest per se performance and significant positive SCA effect while, the hybrids Kufri Jyoti × Kufri Chipsona 1 and MS/95-117 × TPS 13 had the highest per se performance and significant positive SCA effect along with heterobeltiosis in 90 days harvest condition for tuber yield per plant.
