Production of cold tolerant wheat doubled haploid lines and evaluation of production methods

This research was conducted to compare haploid production methods in wheat using chromosome elimination by wheat x maize crosses. The three methods used were a) classic b) detached tiller c) intermediary. Emasculation methods (scissors and foreceps , hot water) were also compered. Parental material...

Summary:This research was conducted to compare haploid production methods in wheat using chromosome elimination by wheat x maize crosses. The three methods used were a) classic b) detached tiller c) intermediary. Emasculation methods (scissors and foreceps , hot water) were also compered. Parental material were2 Fl wheat genotypes (female parents) and and maize genotypesHl(KSCI08), H3(KSC301), H7(SC704) hybrids. The traits studied were: seed set, embryo formation, and haploid plant production. The comparison among these methods revealed that the B method with scissors emasculation was superior with respect to seed set, embryo formation, and haploid production. Amongst the maize genotypes for seed setting H7H3Hl were ranked. Combination ofC method with H7 had highest seed set 81.09%, C method with HI highest embryo formation 19.06% and and A method with H3 had highest haploid production i.e 53.7%.
