植物结实多受环境条件和育种家已知的和预计有利于人工杂交成功的条件所影响。大多数作物的杂交操作都是小规模的,而文献中有关人工控制环境条件提高种子结实方法的资料却很少。甘蔗育种与大多数大规模的、费用昂贵的异花授粉作物育种有所不同。象我们这样的甘蔗育种站,每年要从一千多个杂交组合中生产20万粒左右有活力的种子。因此,通过控制 The firmness of plants is often influenced by environmental conditions and conditions known to breeders and that are expected to be successful in manual crossbreeding. The crossover operations in most crops are small-scale and there is very little literature in the literature on ways to artificially control environmental conditions and improve seed quality. Sugarcane breeding differs from the breeding of most large-scale, costly cross-pollination crops. Sugar cane breeding sites like ours produce about 200,000 or so vibrant seeds each year from more than 1,000 cross combinations. Therefore, by controlling
