摘要
2000—2002年在甘肃的夏河、碌曲和天祝等地,对自国际干旱农业研究中心引进的4 个箭舌豌豆品系2505,2556, 2560 和2566的原种及其选育后代(已表现稳定的第3 代),以及当地狭叶野豌豆333/A品种进行了形态特异性研究。结果表明,1)各新品系较原种最大的形态特性差异是千粒重极显著增加,平均增加66%左右。2)各新品系及333/A间亦存在明显差异,主要表现为:2505-3 的花期最早;2556-3 的叶片为椭圆形,而其它品系为条形;2560-3的种子群体为杂色,而其它品系种子群体个体间表观一致;2566的花为白色, 而其它为紫红色。
Distinctness of morphological characteristics was evaluated in Xiahe, Luqu, Tianzhu of Gansu province from 2000 to 2002. A local Vicia angustifolia commercial cultivar named 333/A, four Vicia sativa lines introduced from ICARDA and their third selective generation were included in this study. The result shows that the new lines have a significant increase of 1 000 seeds weight than the old ones (P<0.01), and the average increase is about 66%. There is also a significant difference among new lines and 333/A cultivar. The 2505-3 line has earliest flowering stage compared to others. Leaf shape of 2556-3 line is elliptic, and others are bar-shaped. Seed capsule color of 2560-3 line is varied though others exhibit uniformly among individuals. The 2566 line has white flower color while others are mauve.
