Studies were carried out on the process of flowering.on the crossing technique, and on the set percentagein artificial crossing, for tne research of peanut breeding. The pollens began to flow out at about 9 p.m. and completely flowed out until 2 to 3 a.m. onthe next day. Under natual conditions, 30 to 40%flowers had been pollinated by 3.a.m. and mostpistils were feritilized at about 10 a.m. The pollinized flowers withered in the same afternoon. Crossingoperation was facilitated by using the raised. whichwere about one foot high from the level and borderedby wooden frames. Both parents were arranged systematically on the beds. In this case one operator waspossible to emasculate 36.3 flowers per hour or topollinize 88.8 flowers per hour.
