通过对6个参试品种的主要农艺性状、生育期、抗逆性、产量进行综合比较分析,选出适合本地栽培的杂交中籼新品种。结果表明:D优68、冈优527米质优良、丰产性好、抗逆性较强,是理想的杂交中籼新品种;冈优22虽具有良好的农艺性状,且产量较高,但米质中等偏下;两优培九具有分蘖力强、穗大粒多、优质、抗性中等、出米率高等优势,在提高肥力及栽培水平条件下,增产潜力较大。
Through the comprehensive comparative analysis of the main agronomic traits, growth period, stress resistance and yield of 6 tested varieties, the new mid-season indica hybrid rice suitable for local cultivation was selected. The results showed that D You 68 and Gangyou 527 were the ideal mid-season indica hybrid rice varieties with good grain quality, high yield and strong resistance. Gangyou 22 had good agronomic characters and high yield Middle-lower in quality; Liangyoupeijiu has the advantages of strong tillering ability, spike large grain, high quality, moderate resistance and high rice yield. Under the condition of increasing fertility and cultivation, the potential for yield increase is larger.
