[6] The Rutgers tomato, at its peak, made up more than 60% of all commercial tomato sales. [7] The Rutgers tomato plummeted in popularity with commercial farmers in the 1960s.
1 For tomatoes with determinate stem growth, paprika and aubergines. In tomatoes with indeterminate stem growth and only one sympodial branch at the corresponding axis, the apical side shoot formation occurs concurrently with the emergence of the inflorescence (Principal growth stage 5), so that the coding within principal growth stage 2 is not necessary
