Повторні добори за масою насіння в лініях-закріплювачах стерильності соняшнику

Abstract

A possibillity to increase seed weight of selfed lines of sunflower by means of repeated selection is confirmed. Some sublines possessing a higher 1000 seed weight than that in the original ones are singled out. It is established that in most cases seed weight increase at the repeated selection did not reduce the number of seeds per head and was accompanied by plant productivity improvement
