High green fodder yielding new grass varieties
Abstract
Two high biomass yielding forage grass varieties one each in Cumbu Napier hybrid and Guinea grass have been evolved at the Department of Forage Crops, Centre for Plant Breeding and Genetics, Tamil Nadu Agricultural University, Coimbatore and identified for release at national (All India) level as Cumbu Napier hybrid grass CO (BN) 5 and Guinea grass CO (GG) 3 during 2012 and 2013 respectively. Cumbu Napier hybrid grass CO (BN) 5 secured first rank at all national level with reference to green fodder yield (2010), dry matter yield (2009 and 2010), crude protein yield (2011) and crude protein per cent (2010) while Guinea grass CO (GG) 3 ranked first at All India level for green fodder yield in 2010, 2011 and 2012, dry matter yield in 2010, 2011 and 2012 and crude protein yield in 2010, 2011 and 2012. Cumbu Napier hybrid grass CO (BN) 5 had recorded significantly higher mean green fodder yield (GFY) of 1082 q/ha/year, dry matter yield (DMY) of 239.03 q/ha/yr and crude protein yield (CPY) of 18.32 q/ha/yr in AICRP on Forage crops trials over the qualifying and national check varieties. Similarly, Guinea grass CO (GG) 3 too registered a higher mean GFY, DMY and CPY of 1082.4, 229.3 and 20.5 q/ha/year respectively over the qualifying and national check varieties.
