“30选”恢复系是从IR2153—159—1—4品系中系选育成。它的恢复力强,一般配合力高,多抗性和光温反应保持了原品系的特点,抗白叶枯病、黄矮病,中抗稻瘟病,抗褐飞虱,较耐寒。本身为感温型,但与珍汕97、V20、二九南1号、珍白等野败质源不育系配组,杂种一代呈弱感光性。用“30选”配制的组合作晚稻栽培,较适应华南晚季的生态特点。它不同于过去所选育的恢复系,如1、2、3、4、5,6、7号等,因这些恢复系与野败质源不育系配组育成的杂交组合,均属于感温型,在华南作晚稻, The “30” restorer lines were selected from the IR2153-159-1-4 lines. Its resilience is strong, its general combining ability is high, its resistance and photothermal response keep the characteristics of original lines, bacterial blight, yellow dwarf virus, medium blast resistance and brown planthopper resistance. Itself is a temperature sensitive type, but with Zhenshan 97, V20, two nine South 1, Zhenbai and other wild and vestigial sterile line with the group, the hybrid generation was weak photosensitivity. The combination of “30 selected” for late rice cultivation, more suitable for the ecological characteristics of southern China in late seasons. It is different from the restorer lines selected in the past, such as 1, 2, 3, 4, 5, 6, and 7. Because these restorer lines are bred with wild-type CMS lines, Type, late rice in southern China,
