Screening of rice (Oryza sativa L.) genotypes for root characters related to drought tolerance and its association with yield under aerobiccondition

problem in major rice growing areas where there is acute scarcity of water and rainfed cultivation depends on the seasonal rainfall. So, order to overcome for cultivation, breeders have made prompt efforts breed genotypes which can tolerate drought stress condition. develop such an efficient breeding programme, selecting plants with desirable root characters one objectives that enables withstand Hence, present investigation was carried under aerobic condition evaluate 21 released by recognized agricultural institutes/universities tolerance whose potentiality conferred traits also correlation studies grain yield taking field trial involving same genotypes. The be done PVC pipes as well polythene bags. Eight viz., MAS-26, MAS -946-1, CR DHAN-204, DHAN- 206, DHAN-210, DRR DHAN-41, DHAN 54, DHAN-55 check variety Belgaum Basmati showed significantly superior mean values most traits. had positive significant association length, volume, root/shoot ratio number indicating perfect criteria selection genetic improvement tolerance. Therefore, programme suitable these potential donors resistance programme. &nbsp
