- Abstract
Sugarcane cultivated over more than five million hectare area in the world. Uttar Pradesh in the Subtropical region of India is an important sugarcane growing zone. The anthocyanin accumulation may protect sugarcane plants to oxidative damage during winter season and imperative resistance to cold. It also mitigates photo oxidative injury in leaves by efficiently scavenging free radicals and reactive oxygen species. The studies were made using twelve popular sugarcane varieties i.e. CoSe 12232, CoSe 11453, CoS 08272, UP 05125, CoS 08276, CoS 767, Co 0238, Co 05011, CoSe 01434, CoS 08279, CoSe 03234 and CoS 8436 were planted under natural condition at Sugarcane Research center Muzafferanagar during 2015-17 and 2016-18 in autumn planting and evaluated for anthocynin contents during winter season. LTM leaf were used in determine the anthocynin contents during winter season in the month of January 2nd week for both the year when average minimum temperature was 2.8°C in both year. Higher anthocyanin accumulation (O.D above then 1.00 μgm/gm) was observed in Co 0238, CoS 08279, CoSe 03234 and Co 05011. The sucrose % in juice and NMC/ha was also higher in theses varieties as compare to other tested varieties. The TAC (total anthocynin contents) is above 1.00 μgm/gm of leaf tissues be considered in possesses hardness against the cold injury. Hence, the study concluded theses three varieties having maximum tolerance to low temperature and may be recommended for cultivation under winter atmospheric temperature.
