Varieties of Italian millet vary very much in their height.An experience in the inheritance of plant height in this millet is recorded here.In 1933 a cross was made between two pure lines.S.I.1646and S.I.2485(vide illustration.)Both of these had a duration of 85 to 90 days.A first generation of 15 plants was raised.These were widely spaced with a view to selfing.Their average height was 119 cm. Contemporary to the F1 the two parents were also raised.The average height of 200 plants of the tall patent was 111 cm.and of the short parent 75cm.One of these fifteen F1 plants,i.e.,No.S.I. 2676 gave in the second generation 219 tall plants with an average height of 104cm.(85-125cm)and 67 short plants with an average height of 66cm.(45-80cm.)The segregation was sharp.there being no doubtful cases during the classification.
