对新近育成的28个杂交中稻组合(以扬两优6号为对照,共计29个)的丰产性、稳产性、适应性及抗病性等性状进行了综合鉴定,两系杂交组合有24个,占参展的82.76%;而三系杂交组合只有5个,占参展的17.26%;米质优良的两系杂交组合有13个,占参展两系杂交组合的54.17%;在单产比对照增产8个杂交组合中,两系杂交组合有7个;三系杂交组合只有一个。全生育期比扬两优6号短10 d以上的有15个,均为两系杂交组合。
A total of 28 newly cultivated hybrid rice combinations (a total of 29 in Yangliangyou 6) were identified for their high yield, stability, adaptability and disease resistance. Among them, 24 Accounting for 82.76% of the total exhibitors; only three of the three-line hybrids accounted for 17.26% of the total exhibitors; 13 good-quality two-line hybrids accounted for 54.17% of the two-line hybrids; In the hybrid combinations, there are seven lines in two lines and only one in three lines. The whole growth period was 15 days shorter than that of Yangyougyou 6, which was more than two dwarf hybrid combinations.
