Carrot root being used as vegetable and salad due to the nutritional value, hence consumers demanding carrot production. Thus, the production can be achieved by an understanding of the genetics of root traits namely root length, root weight, root diameter, core diameter, flesh thickness and root to top (shoot) ratio. Thus, the results assist in the development of carrot hybrids or varieties. Genetic analysis of economic traits of carrot was estimated through three cross combinations, and the results revealed the existence of additive [d], dominance [h], additive × additive [i], additive × dominance [j] and dominance × dominance [l] gene actions. The nature and magnitude of gene interaction and effects showed the importance of the inheritance modes, and the complimentary type of non-epistatic gene action of traits could be used for the exploitation of heterosis through favourable positive [h] and [l] gene interaction and effects. This information on root genetics aided to the adoption of suitable breeding method, handling and selection of segregates with desirable economic traits.

由于营养价值，胡萝卜根被用作蔬菜和沙拉，因此消费者要求生产胡萝卜。因此，可以通过了解根系性状的遗传学来实现产量，即根长，根重，根部直径，芯部直径，果肉厚度和根冠比。因此，结果有助于胡萝卜杂种或品种的开发。通过3种交叉组合对胡萝卜经济性状进行遗传分析，结果表明存在添加剂[ d ]，优势[ h ]，添加剂×添加剂[ i ]，添加剂×优势[ j ]和优势×优势[ l]。]基因作用。基因相互作用的性质和大小及其效应表明了遗传模式的重要性，性状的非上位性基因行为的互补类型可以通过积极的[ h ]和[ l ]基因相互作用和互作来进行杂种优势的开发。效果。有关根遗传学的信息有助于采用合适的育种方法，处理和选择具有理想经济性状的分离株。
