The surgar-fruit cane yield as affected by main yield characters

Main yield characters such as stalk length, diameter, effective stalks per hectare and cane yield were analysed using the correlation and path coefficient of 12 varities both for suger and fruit use. The results showed that stalk length and effective stalks per hectare were significantly or highly significantly correlated with cane yield. And the stalk diameter was not significantly negatively correlated with cane yield. Among the characters, stalk length was not significantly positively correlated with effective stalks per hectare. Stalk diameter was slightly negatively correlated with effective stalks per hectare, and significantly negatively correlated with stalk length specially. The direct effect and total contribution of effective stalks per hectare to yield ranked the first, the stalk length and diameter ranked the second and third. Because the using type has changed, in breeding and field cultivation of sugar-fruit cane, it should be aimed at higher effective stalks, while most paid more attention to stalk diameter too. To obtain higher economic effect, coordination of three characters, seems important.
