Is the miniature bowl lotus determined by variety gene or artificial technology?

The varieties of water lily are divided into four types: large, medium and small, which are determined by genes. If it is a seed, you can't tell the model. Let's talk about the difference between lotus seed lotus root and vegetable lotus root. Lotus seeds and lotus roots are only one thumb thick and long, and consist of two or three sections. The first section has terminal buds, the middle section saves thumb size, but it is thin and not obvious, and the last section is smaller and longer than the tail finger. Let's talk about the basic similarities between vegetable lotus and bowl lotus. But the cabbage lotus is thicker than the bowl lotus, and usually consists of seven or eight swollen lotus roots. But many profiteers will cut off the cabbage lotus and bring a terminal bud in the first two or three paragraphs. The tail of the lotus root is thicker than the thumb, and the swollen part in the middle is described as a thick circle.
