随着茄子杂交种在生产上逐渐应用和推广,首先遇到的是茄子杂交种的制种问题。如何保证杂交种子纯度达到98％以上,发芽率达到85％以上,净度95％以上,而又降低杂交种的成本,这是当前需要引起注意的问题。茄子种子小,数量多,繁殖系数高,用种量少,一般获得一个杂交果,可得到500—1000粒种子,如1亩地按定植3000株计算,只需要4—5个杂交果就够用了。每100—150个杂交果可采0.5公斤种子。只要严格正确地掌握制种技术,就可以提高杂交种子的产量和质量。
With the eggplant hybrids gradually applied in the production and promotion, the first encounter is the seed production of eggplant hybrids. How to ensure that the purity of hybrid seeds reaches more than 98%, the germination rate of more than 85%, the clarity of more than 95%, while reducing the cost of hybrids, which is the current need to pay attention to the problem. Eggplant seed small, large number, high multiplication coefficient, with a small amount of seed, generally get a hybrid fruit, can get 500-1000 seeds, such as 1 acres of land by planting 3000, only 4-5 months of fruit is enough used. Each 100-150 fruit can be collected 0.5 kg seed. As long as strict and accurate grasp of seed production techniques, we can improve the yield and quality of hybrid seeds.
