Interpretive Summary: Six sorghum [Sorghum bicolor (L.) Moench] pollinators were developed from random mating using a recurrent selection followed by pedigree methods and released by the Kansas State University Agricultural Research Center, Hays, KS, in August 2017. The released pollinator (R) lines have been evaluated in hybrid combinations over several environments for agronomic and yield traits. These lines were selected for release based on their agronomic desirability and unique combination of drought and stalk rots tolerance, grain quality traits, and high yield potential in hybrid combinations of importance to sorghum breeders. Also these R lines are with more pollen production and perfect sync with most of the adapted seed parents having A1 cytoplasmic male sterility background for more grain sorghum hybrid seed production.

Technical Abstract: Six sorghum [Sorghum bicolor (L.) Moench] pollinators [KS142R (Reg. No. PI XXXX), KS143R (Reg. No. PI XXXX), KS144R (Reg.No. PI XXXX), KS145R (Reg. No. PI XXXX), KS146R (Reg. No. PI XXXX) and KS147R (Reg. No. PI XXXX) were developed from random mating using a recurrent selection followed by pedigree methods and released by the Kansas State University Agricultural Research Center, Hays, KS, in August 2017. The released pollinator (R) lines have been evaluated in hybrid combinations over several environments for agronomic and yield traits. These lines were selected for release based on their agronomic desirability and unique combination of drought and stalk rots tolerance, grain quality traits, and high yield potential in hybrid combinations of importance to sorghum breeders. Also these R lines are with more pollen production and perfect sync with most of the adapted seed parents having A1 cytoplasmic male sterility background for more grain sorghum hybrid seed production.
