为解决培矮64s在漳州就地繁殖难的问题,引进核心种子繁殖的原原种或原种作为种源,于大寒至小寒播种,通过培育越冬秧,延长营养和生殖生长期,利用5月份24℃以下的低温,促进颖花向可育方向转化,结实率可达5755%~4903%,符合两用核不育系繁殖指标。晚季采取倒种栽培,虽可少量结实,但没有生产价值。
In order to solve the difficult breeding problem of Pei’ai 64s on-site in Zhangzhou, the original seed or original seed of core seed breeding was introduced as seed germplasm and sowed in Osamu and Osamy. By cultivating overwintering seedling and prolonging the period of nutrition and reproductive growth, The low temperature below 24 ℃ promoted the transformation of spikelets to fertile direction with the seed setting rate of 5755% -4903%, which accorded with the reproductive index of dual-purpose nuclear sterile lines. In late seeding cultivation, although a small amount of strong, but no production value.
