北京地区生态条件下木豆引种适应性试验

为扩大木豆品种资源,筛选适合北京地区生产上利用的优质资源,对从中国广西引进的MN1,MN5和从印度引进的ICPL93173,ICPL93174,CPL85010,ICPL86012,ICPL99066,ICPL93081,ICPL8809,IC-PL93097个木豆品种在北京进行了适应性、生长动态和产量构成的观察。结果表明,(1)引进的木豆品种在北京地区为一年生;5月下旬播种,生育期在150 d内的品种均能够正常成熟;(2)MN5,ICPL93173,IC-PL93174,CPL85010为早熟品种,籽粒产量较高,在北京地区种植适宜收获籽粒;MN1,ICPL93081,IC-PL93097为中熟品种,可以收获部分青荚做蔬菜;ICPL86012,ICPL99066,ICPL8809生育期均在150 d以上,为晚熟品种,可作饲用或绿色植被植物;(3)木豆单株荚数为30~115荚,百粒重5.47~8.93 g,单株产量3.09~27.0 g;在供试的10个品种中,ICPL93174和MN5生育期短、株高生长快、叶面积指数大、籽粒产量较高。

Adaptation research of Pigeon Pea in Beijing

Ten varieties of pigeon pea from Guangxi in China and India were investigated on adaptability,growth dynamics and yield factors in ecological condition of Beijing.The result showed these varieties become annual in Beijing.The varieties that finished their developmental period in 150 days can mature when seeds were sowed in late May.MN5,ICPL93173,ICPL93174,CPL85010 are rare ripe and high yield variety,their mature seeds can be harvested in Beijing region.MN1,ICPL93081,ICPL93097 are medium maturing varieties,their fresh legumen may be picked as the vegetables.The developmental period of ICPL86012,ICPL99066,ICPL8809 are over 150 days and they may be planted as feedstuff or vegetation.In general,pods per plant are between 30 and 115,100-seed weight is from 5.47 to 8.93 gram and yield per plant is between 3.09 and 27.0 gram.The ICPL93174 and MN5 display dominance for shorter developmental period,quickly growth,high leaf area index(LAI)and high yield among ten varieties.
