Abstract: The prresentt rresearrch endeavorr was underrttaken tto accellerratte tthe wheatt iimprrovementt prrogrramme newlinetthrrough devellopmentt,, dettecttiion and charractterriizattiion off rrye iinttrrogrressed brread wheatt rrecombiinantts att iin newlineviittro and iin viivo llevell fforr drroughtt ttollerrance and yellllow rrustt rresiisttance.. Fiive ttrriittiicalles,, Hiimallayan rrye newlineand varriious wheatt genottypes werre uttiilliized as tthe parrentts iin tthe wiide hybrriidiizattiion prrogrramme.. Among newlinetthe diifffferrentt wheatt genottypes,, C--306,, VL--829 and Tyarrii--3 had hiighestt seed settttiing ffrrequency off 30..67 newlineperr centt,, 27..27 perr centt and 17..41 perr centt,, rrespecttiivelly,, iin wheatt x rrye hybrriidiizattiion prrogrramme.. The newlinettrriittiicalle x wheatt and wheatt x rrye rrecombiinantts werre ffurrttherr subjjectted tto IImperatta cylliindriica mediiatted newlinechrromosome elliimiinattiion apprroach off doublled haplloiidy brreediing.. The varriiabiilliitty iin tthe haplloiid newlineiinducttiion parrametterrs was obserrved tto be underr genettiic conttrroll fforr embrryo fforrmattiion and rregenerrattiion,, newlinewhiille pseudoseed fforrmattiion was onlly affffectted by auxiin ttrreattmentt.. Among tthe diifffferrentt generrattiions,, newlinetthe backcrross generrattiions viiz..,, BC1F1 and BC1F2 werre ffound tto exhiibiitt siigniiffiicantt posiittiive rresponse newlinettowarrds haplloiid iinducttiion parrametterrs iin botth ttrriittiicalle x wheatt and wheatt x rrye hybrriidiizattiion.. The newlinedettecttiion off new rrecombiinantts fforr iinttrrogrressiion off rrye chrromattiin tthrrough mollecullarr cyttogenettiic newlineanallysiis rrevealled 1BL..1RS ttrransllocattiion iin 33 lliines ((55..93 perr centt)),, 1BL..1RS ttrransllocattiion allong wiitth newlinesubsttiittuttiion iin 5 lliines ((8..47 perr centt)),, 1BL..1RS ttrransllocattiion allong wiitth addiittiion iin 8 lliines ((13..56 perr newlinecentt)),, substtiittuttiion off siinglle paiirr off rrye chrromosomes iin 5 lliines ((8..47 perr centt)) and addiittiion off rrye newlinechrromattiin iin 1 lliine ((
