Abstract

Groundnut TMV 14 is high yielding Spanish bunch genotype. It is the cross derivative of VRI 6 x R 2001-(2) through pedigree method of breeding Groundnut TMV 14 (2124 kg/ha) has given higher pod yield over the check varieties; 11.5 % increase over VRI (Gn) 6 (1904kg/ha); 15.2 % over check variety TMV Gn 13 (1844 kg/ha) during Kharif season. Groundnut TMV 14 (2286 kg/ha) has given higher pod yield over the check varieties; 29.7 % increase over VRI(Gn)6 (1762kg/ha); 32.3 % over check variety TMV Gn 13 (1727kg/ha) during rabi season under irrigated condition.For oil yield during Kharif season (720 kg/ha), variety TMV 14 gave 14.6%(720kg/ha)increase over VRI(Gn)6  (628kg/ha); 10.7 % over TMV Gn 13 (650 kg/ha) during Kharif season. Similarly for oil yield during  rabi season under irrigated condition(775 kg/ha), variety TMV 14  gave 33.3% increase over VRI(Gn)6  (581 kg/ha); 27.2 % over TMV Gn 13 (609 kg/ha).For dry haulm yield (3640 kg/ha), variety TMV 14 gave 12.3% increase over VRI(Gn)6  (3240kg/ha); 22.6 % over TMV Gn 13 (2970 kg/ha) during Kharif season. For dry haulm yield (3758 kg/ha) the variety TMV 14 gave 13.02% increase over VRI(Gn)6 (3326kg/ha); 4.03 % over TMV Gn 13 (3604 kg/ha) during rabi under irrigated condition. Shelling turnover of TMV 14 (70.6%) comparable with VRI(Gn)6 (68%). Sound Mature Kernels are more in TMV 14 (93.9%) compared to VRI(Gn)6 (92%). 100 kernel weight are more in TMV 14 (38g) compared to VRI(Gn)6 (35.0) and TMV Gn 13( 34.6).The variety TMV 14 matures early in 95-100days.For Late leaf spot and rust diseases, variety TMV 14 has shown moderated resistance incidence compared to check varieties.TMV 14 has shown tolerance against Spodoptera litura, thrips and Heliathis armigera and leaf miner.
