有性杂交是当前花生常规育种的重要手段之一。一九七六年我们开始杂交育种,一九七七年认真总结了前一年的经验教训,从播种到拴针等主要环节,作了一些必要的改进,加上杂交过程中温度条件比较有利,工效、受精率和结实率均有大幅度提高。七七年,我们做了16个组合,授粉总花数为2536朵,拴果针1511个,收获荚果1468个。平均受精率为59.6％,结实率为57.9％,比七六年受精率和结实率提高接近5倍,其中省花生育种协作组分配的8个组合,平均受精率为64.7％,结实率为62.6％,最高的一个组合,受精率和结实率分别高达90.4％与85.3％,超过了子想的结果。
Sexual crossbreeding is one of the important means of routine peanut breeding. In 1976, we started hybrid breeding. In 1977, we carefully summed up the lessons we learned from the previous year. We made some necessary improvements from the main aspects such as sowing to tethering. In addition, the temperature conditions during the hybridization process were favorable , Ergonomics, fertilization rate and seed setting rate have greatly increased. In the last seven or seven years, we made 16 combinations with a total number of pollination of 2536 flowers, 1511 tied needles and 1,468 pods. The average fertilization rate was 59.6% and the seed setting rate was 57.9%, which was nearly five times higher than that of the seventy-six years. The average fertilization rate was 64.7% and the seed setting rate was 62.6 %, The highest one, fertilization rate and seed set rate as high as 90.4% and 85.3%, respectively, more than the desired result.
