Genetical analysis of 5 parents and 10 hybrids arising from 5x5 half-diallel cross for the uptake of NPK under pot culture at 35, 70 and 105 days after transplanting revealed that dominance gene effect was responsible for the uptake of nitrogen and potassium. The uptake of phosphorus was governed by additive gene effect. Parents, Marglobe Supreme and Peterson, appeared to be more suitable for breeding programme due to their high general combining ability effects. The hybrids, Punjab Tropic × KS-20, Punjab Tropic × Peterson, Punjab Tropic × Roma Super, KS-20 × Roma Super and Peterson × Marglobe Supreme performed well in relation to higher efficiency in nutrient uptake.
