گزارش نهایی بررسی و مقایسه عملکرد هیبریدهای سورگوم دانه ای و تعیین سازگاری آنها با شرایط اقلیمی مشهد

To determine the most suitable sorghum grain variety, ten sorghum varieties, namely Rubino, Gold mine, Pacific 810, Durado-Dr, Bravo-M, Tamaran, N,K. 2776-w, Goldrush-2, Ruby, and Bravo-E Were compared in randomiaed comlete block design (RCBD) with four replications over a three years period (1989-1991) in Mashhad. The results of the simple and also combined analysis of variance on the grain yield over the three years and using the stability indexes (variation range and variance of hybrid means in the three years) showed the significant differences between years and varieties. Comparisons of variety mean yields with duncan multiple range test and stability indexes showed that variety "Rubino" with 7.718 tons per hectar was the best and stable variety.
