建国以来,我省汉中等主要稻区进行了三至五次品种更换。引进品种大面积推广的有胜利籼、云南白、华东399、桂花球、农垦57、珍珠矮11号、二九矮4号、广矮3784、早金凤、南京11号、南优2号、3号、威优6号、威优圭以及原子2号、公交10号、科情3号、南粳8号、10号、梅六早、红梅10号等。我所育成品种中,粳稻推广面积在3万亩以上,籼稻在10万亩以上(最大达70万亩)的先后有沙蛮1号、稗09、高籼64、华矮选、大57、39—1,正在扩大推广的有三珍96、1561凤、24龙26、菲改A×691等。几十年来在品种工作上取得了一些经验,其中有许多就是在“吃一堑长一智”的失败教训中积累起来的。由于人事的变迁,有些教训没有被当作社会财富接受下来,至今还在反复重犯。为使今后水稻品种工作少受损失,有必要对一些基本经验进行总结探讨。
Since the founding of the People’s Republic of China, Hanzhong and other major rice-producing areas in our province have carried out three to five varieties replacement. The introduction of varieties of large-scale promotion have victory Indica, Yunnan white, East 399, sweet-scented osmanthus ball, Nongken 57, pearl short 11, 29 dwarf 4, Guang short 3784, early Jinfeng, Nanjing 11, No. 3, Wei You 6, Wei Yougui and Atom 2, Bus No. 10, Section 3, Nanjing No. 8, No. 10, Mei Liu early, Hongmei 10 and so on. Among the cultivars I cultivated, the popularization area of japonica rice was more than 30000 mu, the sativa 1, barnyardgrass 09, indica indica 64, 39-1, are expanding the promotion of Sanzhen 96,1561 Phoenix, 24 Dragon 26, the Philippines to change A × 691 and so on. Some decades of experience gained in breed work, many of which have been built up in the failed lesson of “eating one long, one wise”. Due to the change of personnel, some lessons have not been accepted as social wealth, and are still repeatedly repeated. In order to make the work of rice varieties suffer less in the future, it is necessary to summarize some basic experiences.
