A high yielding new ragi variety Paiyur 2
Abstract
A high yielding long duration ragi culture DPI 20030 was developed at Regional Research Station, Paiyur and released asPaiyur 2 during 2008 at State level. It is a derivative of the cross involving VL 145 x Selection 10. It yields on an average2527 kg/ha of grain and 4200 kg/ha of straw under rainfed condition. Besides high yield, compact incurved fingers, uniformmaturity, non-lodging nature and moderate protein content (7.2 %) are the added advantages of this culture. The 1000 grainweight of this culture is 2.9 g as compared to 2.71 g of GPU 28. This culture recorded a grain yield of 2527 kg/ha which was14.6 % increase over the check GPU 28 (2206 kg/ha) and 6.6 % over the check Paiyur 1 (2371 kg/ha) in station trials andfarmers fields. It recorded a grain yield of 2312 kg/ha which was 9.36 % increase over the check GPU 28 (2114 kg/ha) and10.62 % over the check Paiyur 1 (2090 kg/ha) in OFT’s conducted during kharif 2006 in 40 locations. It has given the meanyield of 2535 kg/ha which was 4.67 % increase over the national check PR 202 (2422kg/ha) in All India Coordinated Trialstested over three years from 2002 to 2004 ranking fourth, ninth and fourth in grain yield tested over 19, 14 & 14 locationsrespectively.
