  This invention relates to compounds of the formula: ##STR1## wherein R.sub.1 is an optionally substituted alkyl or alkenyl group; at least one of R.sub.2, R.sub.5 and R.sub.6 is ##STR2## wherein (1) when R.sub.2 is ##STR3## R.sub.5 is a hydrogen atom, an alkyl group or a halogen atom and R.sub.6 is a hydrogen atom or an alkyl group, (2) when R.sub.5 is ##STR4## R.sub.2 is an alkyl group and R.sub.6 is a hydrogen atom or an alkyl group, (3) when R.sub.6 is ##STR5## R.sub.2 is an optionally substituted (C.sub.1 -C.sub.6) alkyl or a (C.sub.3 -C.sub.6) alkenyl group and R.sub.5 is a hydrogen atom, a (C.sub.1 -C.sub.6) alkyl group or a halogen atom, and (4) when R.sub.2 and R.sub.6 are both independently ##STR6## R.sub.5 is a hydrogen atom or an alkyl group; Y is a hydrogen atom or an alkyl group; X is a hydrogen atom, a halogen atom, a trihalomethyl group and the like; and n is an integer from 1 to 3; or the agronomically acceptable alkali metal or acid addition salts thereof. These compounds are useful as chemical hybridization agents on moncotyledonous crops and are especially effective in wheat, corn, barley, rice, rye, triticale and forage crops.

  本发明涉及公式如下的化合物：##STR1## 其中，R.sub.1是可选择取代的烷基或烯基基团；R.sub.2、R.sub.5和R.sub.6中至少有一个是##STR2## 其中，（1）当R.sub.2是##STR3##时，R.sub.5是氢原子、烷基或卤素原子，R.sub.6是氢原子或烷基；（2）当R.sub.5是##STR4##时，R.sub.2是烷基，R.sub.6是氢原子或烷基；（3）当R.sub.6是##STR5##时，R.sub.2是可选择取代的（C.sub.1-C.sub.6）烷基或（C.sub.3-C.sub.6）烯基基团，R.sub.5是氢原子、（C.sub.1-C.sub.6）烷基或卤素原子；（4）当R.sub.2和R.sub.6都独立地为##STR6##时，R.sub.5是氢原子或烷基；Y是氢原子或烷基；X是氢原子、卤素原子、三卤甲基基团等；n是1到3的整数；或其农学上可接受的碱金属或酸加成盐。这些化合物对单子叶作物具有化学杂交剂的作用，特别是对小麦、玉米、大麦、稻米、黑麦、小黑麦和饲料作物具有很好的效果。

  The present invention relates to N-alkyl-2-aryl-4-oxonicotinates, N-alkyl-5-aryl-4-oxonicotinates, N-alkyl-6-aryl-4-oxonicotinates and N-alkyl-2,6-diaryl-4-oxonicotinates and their use as plant hybridization agents especially useful in wheat, barley and corn. These compounds are particularly active as chemical gametocides and possess a high degree of male/female selectivity. Moreover, these compounds are relatively noninjurious to both corn and wheat crops. The fact that these chemicals possess a high degree of male sterility without affecting female fertility makes them very useful as chemical gametocides.

  本发明涉及N-烷基-2-芳基-4-羟基吡啶酮酸酯、N-烷基-5-芳基-4-羟基吡啶酮酸酯、N-烷基-6-芳基-4-羟基吡啶酮酸酯和N-烷基-2,6-二芳基-4-羟基吡啶酮酸酯及其作为植物杂交剂的用途，特别适用于小麦、大麦和玉米。这些化合物在化学杂交中具有特别的活性，并具有很高的雄性/雌性选择性。此外，这些化合物对玉米和小麦作物相对无害。这些化学物质具有很高的雄性不育性而不影响雌性育性，使它们非常有用作为化学杂交剂。
