随着芝麻育种工作的不断深入,一些比较高产稳产的分枝型品种(系)相继育成,许多新的品种(系)正在大面积试验、示范和推广应用。但对此类品种(系)产量性状及与产量间的相关回归分析研究报道甚少。在大面积栽培上还存在着密度过大或过小,施肥不当,打顶不彻底,收获后仍上大堆等不 With the deepening of sesame breeding work, some of the more stable varieties of branching varieties (lines) have been bred, many new varieties (lines) are large-scale test, demonstration and promotion. However, little research has been done on the correlation analysis of yield traits and yield between these varieties (lines). In large-scale cultivation there is still too much or too little density, improper fertilization, not topped, after harvest still a lot of other
