针对育种工作中对矮秆、早熟、大粒、抗病以及优质等特异种质的需要,笔者以花药培养为手段,利用其易诱发新突变、产生新类型的特点,在较短的时间内创造出一批各具特色的新种质,并进行了比较系统的鉴定及多年考察,结果简报如下: 1 材料和方法 1.1种质创新 采用常规育种杂交组合及花培后代与生产上推广品种杂交组合的F_1花药进行培养,诱导出的绿苗经低温贮存越
Aiming at the need of special germplasm with short stalk, early maturity, big grain, disease resistance and high quality in the breeding work, the author takes the anther culture as a means to make use of its easy to induce new mutations to produce new types of features and create them in a relatively short period of time A new batch of germplasm with unique characteristics, and carried out a more systematic identification and years of inspection, the results are summarized as follows: 1 Materials and methods 1.1 Germplasm innovation using conventional breeding hybrid combinations and flower breeding progeny and production of hybrid varieties F_1 anther culture, induced by the green seedlings stored at lower temperatures
