摘要
本文研究了杂交早稻新组合威优242在我省正季栽培的生育期,产量和主要经济性状。威优242的生育期比当前生产上的主栽组合品种威优49和鄂早6号明显提早,产量与威优49相近;但比鄂早6号显著增产,很适合在我省三熟制双季稻区作“油菜—早杂—晚杂”等新的栽培模式的配套组合。
The duration of growth period,yield potential and principal economic characters of a new hybridized combination of early rice Wei-You 242 are studied in the normal season of early rice plant-ting in Hubei. The mature period of Wei-You 242 is obviously earlier than that of Wei-You 49, a chief hybridized combination,and that of E-Zao 6,a main variety of early rice. The yield potential is remarkable higher than that of E-Zao 6. Wei -You 242 is very suitable to be used in the new model of production 'colewort - early hybrid rice -late hybrid rice'in the region of the triple crop system with double cropping rice.
