| Abstract: | GS Yumai 21 ranks frist in two years on demonstration tests of Henan province and Yellow Huai river valley experiment in 1988-1993. Its average yield of 85 locations in six years was 416. 2kg per mu and increased by 11. 67% over four check varieties in prefecture,province and state tests. For exampte.the average yield of 11 co-cations in 1992 was 506. 9kg per mu in Yellow -Huai river valley. The highest output was 625. 5kg per mu in production. It was regestered by Henan province and state crop varieties regestation committee in 1992 and 1993 respectively. The characteristics of se-lection include multiple cross of four parents from dissimilar genetic background and complementary characters,extension of selected population,repeated selection artificial inoculation of disease germ, test of fertilization and irrigation,selection of plant type in the field and examination of seed quality in the room et al. The variety with steadily high yield combined short-stem with large spike,high yield and multiple disease-re-sistance. The total planting area of Yumai 21 was over 20 millions mu by 1995 and the variety adapts further planting in Yellow - Hai river valley. |
