Stability Analysis for Quantitative Traits in Sugarcane (Saccharum officinarum)

The experimental material comprising of seven varieties viz., Co 05009, CoH 05262, CoH 05265, CoLk 05201, CoPk 05191, CoJ64(s) and CoPant84211(s) were grown in randomized block design with three replications, in three environments at Agriculture Research Station Ummedganj, Kota North west zone, India during 2009 to 2011. Mean squares due to genotypes were highly significant for tillers population (ha), NMC (ooo ha), cane length (m), cane diameter (cm), single cane weight (kg), yield (t/ha), brix at 300 days, ccs (t/ha) and brix at 250 days. However, Extraction % and Sucrose % at 240 days were no significant. Variety CoPk 05191 was found stable for NMC (‘000 h), yield (t/ha) traits, except Tillers Population(ha), Cane Length (M), Cane Diameter (cm), Single Cane Weight (kg), Extraction (%), BRIX% at 240 Days, BRIX% at 300 Days, Sucrose % at 240 Days and CCS (t/ha), variety CoH 05265 was found stable for Cane Diameter (cm) and Single Cane Weight (kg) traits, except Tillers Population(ha), NMC (‘000 h), Cane Length (M), Extraction (%), yield(t/ha), BRIX% at 240 Days, BRIX% at 300 Days, Sucrose % at 240 Days and CCS (t/ha) while, variety CoH 05262, was also found stable for Cane Diameter (cm) except remaining traits. Hence, these CoPk 05191 CoH 05265 and CoH 05262, promising lines could be recommended for commercial cultivation or could be suitability used in further improvement programme.
