要提高小麦单产,就要有优良品种。一个小麦优良品种从选育到生产上利用,要经过省内区域、生产等一系列试验环节。为此,如何准确拿出较好的试验材料参加试验,使之尽快在生产上发挥作用,不仅是育种者的责任,也是进一步提高小麦产量的主要途径。一、对供试品系即要“求全”还要有重要改进性状对任何一个省内参试品系而言,其适者生存的含义,不仅限于该品系可在某种生态条件下生存下去, To improve wheat yields, there must be good varieties. A good wheat varieties from breeding to production use, to go through the province’s regional, production and a series of test sessions. Therefore, it is not only the responsibility of the breeders, but also the main way to further increase the yield of wheat by accurately taking out the better test materials to participate in the experiment so as to make it play its role as soon as possible. First, for the test line that is to “Seek the whole ” There are important improvements Traits For any one of the province of the test line, the survival of the fittest meaning, not limited to the line can survive under some ecological conditions,
