Abstract
A high yielding mid late maturing clone CoPb 08217 was developed from Co 1158 GC at Punjab Agricultural University, Regional Research Station, Kapurthala, Punjab. It was tested against the popular check varieties CoJ 88 (state) and CoS 8436, CoS 767 and CoPant 97222 in mid late maturity group under All India Coordinate Research Project on Sugarcane its performance during 2010-11 to 2013-14. The clone CoPb 08217 exhibited a mean cane yield of 93.14 (t/ha) as compared to CoS 767 (77.52 t/ha), CoS 8436 (73.44 t/ha) and CoPant 97222 77.30 (t/ha) with an increase of 20.15, 26.82 and 20.49 percent, respectively. It has tall thick cylindrical yellowish green canes, asymmetric auricles (i.e. deltoid / transitional), prominent weather and ivory marks with shallow bud groove. Matures in 300 to 320 days and can be crushed from February onwards. CoPb 08217 significantly out-yielded the checks CoJ 88 and CoS 8436 by a margin of 22.03 % and 28.22 %, respectively in 42 station and AICRP(S) research trials. It is a good ratooner which gave 12.28% higher cane yield as compared to CoJ 88 and 45.90 % higher than CoS 8436. It is at par with CoJ 88 and CoS 8436 for quality in both plant and ratoon crops. It is moderately resistance to both red rot pathotypes CF 08 and CF 09 under artificial inoculation conditions, were also found less susceptible to borer complex as compared to checks. Identification of this variety would add to the varietal diversification in the state in mid maturity group. The clone has been found promising with respect to cane yield, sugar yield and red rot resistance to standards. It is identification and release in the state will help the farmers and sugar industry for sustainable sugarcane production.
