Achievements

Popular varieties developed

• Co V 09-356 (2003 V 46 - Bharani): Released in 2010 by SVRC for Andhra Pradesh. It is high yielding, sucrose rich, erect, early maturing, non lodging variety with excellent ratooning ability and with resistance to red rot (cf 419, cf 671, cf 997 races prevalent in A.P.) and smut. Suitable for water logged and irrigated conditions and also uplands. Suitable for multiratooning. Suitable for for machine harvesting. Recording higher yields in water logged conditions and in Coastal areas with saline irrigation water than other varieties. Gives good quality jaggery. It has become popular in all sugar factory areas in A.P.and also cultivated in Tamilnadu, Orissa and Telangana.
• Co V 94101 (86 V 96): It is high yielding, sucrose rich, early maturing variety with resistance to red rot (cf 419, cf 671, cf 997 races prevalent in A.P.) and smut. It is opening mill cane and suitable for I–D conditions and garden lands. It can not tolerate drought and waterlogging. Gives good quality jaggery. It is cultivated in A.P.and Tamilnadu.
• Co V 92102 (83 V 15 - Kanaka Durga): Released in 2002 by SVRC for Andhra Pradesh. It is high yielding, high tillering, sucrose rich, mid-late maturing variety with good ratooning ability and resistant to red rot (cf 419, cf 671, cf 997 races prevalent in A.P.) and smut. It is suitable for irrigated, rainfed, water logged conditions, problematic soils and also for rainfed late planting. Gives good quality jaggery. It is susceptible to post harvest deterioration. It can be planted after taking rabi pulses/turmeric/elephant yam etc. i.e., in April also. It is cultivated in A.P. and Tamilnadu.
• 93 V 297: It is high yielding, sucrose rich, early maturing variety with thick canes. It is opening mill cane and gives higher recovery in the factories. It is suitable for irrigated and waterlogged conditions. Gives good quality jaggery. It is tolerant to smut but as it became susceptible to cf 419 and cf 671 races of red rot, now confined to uplands and borewell irrigated areas in A.P. and also in Telangana.
• Co V 95101 (91 V 83 – Krishna): Released in 2002 by SVRC for Andhra Pradesh. It is high yielding, sucrose rich, erect, early maturing, opening mill cane with solid cane and longer internodes. It is good ratooner and resistant to red rot (cf 419, cf 671, cf 997 races prevalent in A.P.) and smut. It is suitable for irrigated and waterlogged conditions. Susceptible to GSD and post harvest deterioration.
• CoV 89101(81 V 48): Released in 1996 by SVRC for Andhra Pradesh. It is high yielding, sucrose rich, high tillering variety with resistance to smut. Cane yield and sugar recovery in Krishna district increased by cultivation of this variety but now withdrawn from cultivation due to susceptibility to cf 419 race of red rot. It is widely used variety in crossing programme by breeders from all over India and good number of selections with high sucrose were forwarded to final yield trials.
• Co V 92103 (83 V 288): It is high yielding, mid-late maturing variety and highly suitable for lanka soils. It is resistant to smut and field tolerant to red rot. Mostly it is planted after taking rabi pulses/turmeric/elephant yam etc. i.e., in April in Krishna district of A.P.
• 98 V 95: It is high yielding, early maturing variety with suitable for irrigated and waterlogged conditions. It is resistant to red rot and smut. Cultivated in Krishna district of A.P. both in irrigated and waterlogged conditions.
• 2002 V 48: It is high yielding, mid- late maturing variety with resistance to smut and field tolerance to red rot. It is suitable for irrigated, waterlogged conditions and up lands. Cultivated in Krishna district of A.P. in irrigated and waterlogged conditions and lanka soils.

Other varieties with high potential of yield and quality viz., Co 8013, Co V 92101 (82 V 12), 89 V 74, Co C 85036, 97 V 97, 98 V 100, CoV 05-356 (99 V 30) and CoV 06-356 (2000 V 59) were cultivated in different periods in different factory areas.

Vuyyuru varieties suitable for saline water irrigated conditions: Co V 09-356 (2003 V 46), Co V 92102 (83 V15), CoV 05-356 (99 V 30), Co V 12-356 (2006 V 51), Co V 12-357 (2005 V 96), Co V 13-356 (2006 V 41), Co V 14-356 (2007 V 127).

Major interventions which improved the productivity/recovery of sugarcane

• The herbicides metribuzine @ 1.0kg a.i./ha (or) oxyflourfen @ 0.2 l/ha were effective in controlling weeds as pre emergence or early post emergence (35-40 DAP) application in sugarcane.
• Paired row (2’/4’) planting was found better to facilitate mechanical harvesting instead of wide row planting due to lodging problem in coastal areas.
• Surface or sub-surface drip are equally effective with paired row planting. With drip there was 35% yield increase and 26% water saving.
• Co V 09-356 (2003 V 46) is suitable for delayed harvesting up to 11th month without losing yield and quality and also suitable for delayed crushing upto 48 hours without deterioration in juice quality and reduction in cane weight.
• Substitution of Phosphobacteria @ 8 kg /ha and VAM @ 5 kg /ha combinedly reduced the use of chemical phosphate fertilizers upto 50%.
• Soil application of Trichoderma viride and Pseudomonas aeruginosa at the time of planting reduced the red rot disease intensity drastically and improved the yield and quality.
• Sett treatment with propiconazole @ 0.1% was most effective in control of settborne infection of smut both in plant and ratoon crops.
• Integrated red rot disease management module was developed i.e., exploitation of native potential biocontrol agents and need based foliar spray of the fungicide in combination of other cultural/agronomical strategies has high potential to manage the disease under field conditions.
• Spraying of chlorantraniliprole 0.3 ml / l of water is recommended to manage Early Shoot Borer.
• Field release of egg parasite, Trichograrmma chilonis @50,000/ha at weekly intervals from 4th week after planting upto 90th day will reduce Early Shoot Borer.
• Spraying Acephate / Acetamiprid / Imidacloprid reduced white fly and scale insect incidence.
