一种预测待测猪的窝产活仔数遗传性能的SNP位点组合及方法
摘要：
本发明公开了一种预测待测猪的窝产活仔数遗传性能的SNP位点组合及方法。本发明所提供的SNP位点组合，由猪基因组中序列表中序列1自5’末端起第501位核苷酸、序列表中序列2自5’末端起第501位核苷酸、序列表中序列3自5’末端起第501位核苷酸、序列表中序列4自5’末端起第501位核苷酸和序列表中序列5自5’末端起第501位核苷酸组成。实验证明，采用本发明筛选的5个SNP位点预测可靠性值为0.081，相比BLUP方法提高了13.8％。因此，利用5个SNP位点来预测待测大白猪的窝产活仔数遗传值，可以加快遗传进展，为育种者带来经济效益，具有重要的应用价值。
摘要（英）：

The invention discloses an SNP site combination and a method for predicting alive litter size genetic performance of to-be-tested pigs. The SNP site combination is composed of the 501st nucleotide from the 5'-terminal in the sequence 1, the 501st nucleotide from the 5'-terminal in the sequence 2, the 501st nucleotide from the 5'-terminal in the sequence 3, the 501st nucleotide from the 5'-terminal in the sequence 4 and the 501st nucleotide from the 5'-terminal in the sequence 5 in the genome of pigs. A test proves that prediction reliability value is 0.081 by means of the five SNP sites screened in the invention, which is increased by 13.8% than a BLUP method, so that by means of the five SNP sites, the genetic value of alive litter size of to-be-tested large white pigs can be predicted. The SNP site combination can accelerate genetic progress, brings economic benefit to breeding farmers, and has important application value.
