我们于1951年开始梨的杂交育种,到1977先后27年间分四批杂交,共168个组合,培育6,894个单株。第一批是在1951和1952年进行的,当时辽西梨产区栽培的西洋梨、砂梨经常遭受冻害,我们想通过杂交改进品种的抗寒能力;1956、1957年又做了一批杂交,这次主要是想培育早熟的新品种和品质优良兼能抗病耐寒的晚熟品种。经过二十多年的工作,已培育出一些基本上符合上述要求的新品种,有的已在生产上大面积推广。
We began hybrid breeding of pears in 1951, and crossed with four batches in 1977 for the first 27 years in a total of 168 combinations, breeding 6,894 single plants. The first batch was carried out in 1951 and 1952. Pear and sand pear cultivated in the Liaoxi pear producing area at that time often suffered frost damage. We wanted to improve the cold resistance ability of the hybrids by crossing. In 1956 and 1957, This time, we mainly want to breed precocious new varieties and good late-maturing varieties that are hardy and cold-resistant. After more than 20 years of work, some new varieties that basically meet the above requirements have been bred and some of them have been widely promoted in production.
