2,4-Dichlorophenoxyacetic Acid as an aid to Seed Production when widely separated Solanum Species are crossed

Article metrics

Abstract

AFTER repeated unsuccessful attempts to duplicate Swaminathan's1 technique for overcoming the cross incompatibility between Solanum species, a study was undertaken to determine the causes of seed failure when widely separated Solanum species are crossed. This work showed that some pollen germinated in all attempted crosses between several tuber-bearing series of the genus. Apparently normal pollen tubes were even observed at the bases of S. melongena L. styles when that species was pollinated by S. phureja Juz. and Buk.
