Abstract
Sugarcane clones tolerant to rainfed and waterlogged conditions is the need of the hour as sugarcane yields are drastically reducing. The objective of the study is selection of high yielding climate resilient clones with high yield under rainfed and conditions and waterlogged conditions during 2019-20 to 2020-21. The experiment was carried out in Randomized Block Design with three replications. Gross plot size adopted was 8mt X 0.8mt X 8R = 51.20m2 and Net plot size is 8mt X 0.8mt X 6R= 38.40 m2The clones 2006A223,2009A107 and 2009A252 were found to be significantly superior over the standards,87A298 and 83V15 for NMC,cane yield, ccs yield, yield components.Significant morphophysiological traitslike number of nodes, adventitious roots,total dry matter production per stool,relativewater content were higher in 2006A223 followed by 2009A107and 2009A252 under rainfed conditions where as under water logged conditions the clones2003V46, 2006A223 and 2009A107 were found to be significantly superior over the standards,87A298 and 83V15 for NMC, cane yield, ccs yield, yield components besides quality traits. Significant morphophysiological traitslike number of nodes, adventitious roots, total dry matter production per stool, relative water content were higher in 2006A223 followed by 2003V46, 2009A252 and 2009A107 in Sugarcane.Identification of promising drought tolerant clones based on LAI and SCMR values, water use efficiency, SLA, root volume and leaf proline content highlights the potential of integrating physiological screening in collaboration with breeding selection strategies. In future, the new flood tolerant and promising rainfed and submergence tolerance sugarcane genotypes can can serve as valuable genetic resources for developing climate resilience through targeted breeding efforts.
