豫南稻茬麦区优质高产小麦育种目标探讨

Discussion on Breeding Target for Wheat Following Rice in the South of Henan Province

分析了豫南稻茬麦区小麦育种工作的现状,依据独特的生态气候条件、耕作制度和小麦生产水平,结合几个推广品种的性状特点,提出了应以培育优质高产、稳产、耐湿、多抗、早熟小麦品种为目标。具体性状指标要求:选育半冬性多穗型品种,产量三要素中要突出单位面积穗数和穗粒数,千粒重要求中等或偏上即可,早熟或中熟,灌浆速度快,半矮杆,抗倒伏能力强,耐湿抗病,适应范围广,播期弹性大,抗逆力强。

Status of wheat breeding and advantage of wheat production were analyzed in the wheat following rice field in the south of Henan province. According to the distinct ecology climate condition, farming system and wheal development level in the region,and combining with the characteristics of several spread cuhivars, the wheat breeding objective of fine quality, high and stable yield, endurance to wet, resistance to wheat primary diseases and insect pests and early maturity was put forward .
