为了适应生产和科技发展的需要,四川省培育甘蔗实生苗创造甘蔗新品种的工作,由1954年至1978年已有25年了,曾先后育成经鉴定推广的有川蔗1—13号等新品种(尚有成百个新品系及成千的新材料正在培育选择中)。这些品种具有抗逆性强,适应性广,蔗和糖产量均高的优良特性,深受工农业欢迎,从而代换了土种芦蔗及旧良种印度290、运河点29/116、49/50,促使我省蔗糖生产大发展。据1978年统计我省自育良种已占值蔗总面积的64.8%,产糖率由1964年的7.8%提高到1972年的10.67%。现在不少糖厂已超过11%大关。但在出现新品种的16年实践工作历程中(即从1954年原内江甘蔗试验站到我所截
In order to meet the needs of the development of production and science and technology, Sichuan Province to cultivate sugarcane seedlings to create a new variety of sugarcane work, from 1954 to 1978, 25 years, has been bred by the identification of a promotion of new varieties of Sichuan 1-13 (Hundreds of new lines and thousands of new materials are still under development). These varieties have strong resistance, wide adaptability, sugar cane and sugar yield are high, welcomed by the workers and peasants, which replaces the soil seed sugar cane and old India 290, the canal point 29 / 116,49 / 50, to promote the great development of sucrose production in our province. According to the statistics of 1978, the self-breeding seeds of our province have accounted for 64.8% of the total area of sugarcane, and the sugar yield has risen from 7.8% in 1964 to 10.67% in 1972. Now a lot of sugar has more than 11% mark. However, in the course of 16 years of practice of new varieties (that is, from the original Neijiang sugarcane experimental station in 1954 to what I intercepted
