| dc.description.abstract | Stability analysis was performed on yield data from the co-ordinated rice varietal trials, which were conducted at 13 locations using 34 cultivars (varieties). The data used in the analysis came from the trials conducted in 1993 Yala, 1993/94 Maha and 1994 Yala seasons. The stability parameters (Bi and Ai) and the variance components of the genotype x environment interaction were evaluated for each cultivar. Based on the results of the analysis general and specific recommendations can be made. In the 4 - 4'12month age group the varieties BG 1528, BG 1222 and BG 1959 performed consistently well in all locations and seasons and can be used for general recommendation. In the 3'12month age group BG 1639 and BG 94-1 can be recommended for general use throughout all locations, while in the 3 month group none of the varieties are suitable for general recommendation. Some varieties though not consistent in performance over all seasons and locations, performed well in I or 2 sites in I or more seasons. They are suitable specifically to these sites. Varieties BW 306-2 and AT 90-332 of the 4-4'12 age group can be recommended to Maha- Illuppallarna (in Yala) and Ambalantota (in Maha)respectively. The variety BW 326-3 (3'12 month) can be recommended to Paranthan, while BG 1492 (3 month) can be recommended to Labuduwa, and to Ambalantota and Paranthan in Yala. | |
