ABSTRACT

The seeds of 6 × 6 half diallel progenies of Jatropha curcas were used to evaluate the effects of genotypes (parents and their hybrids) on germination traits of jatropha at Universiti Kebangsaan Malaysia. Germination traits were varied significantly (p<0.01) among the seeds of hybrids and their parents. The germination was started at four days after planting and prolonged until 15 days. Seed germination varied from 58.06 to 92.76% among the parents and 53.43 to 98.96% among the hybrids. The highest germination was observed in the hybrid P2 × P4 and none of the hybrid or parent showed complete (100%) germination. The maximum GI (germination index) and SVI (seedling vigour index) were found in the hybrids P1 × P5 and P1 × P2 and the lowest in P2 × P4 and P3 × P6, respectively. For most germination parameters parents behaved poorly than that of the hybrids.

ABSTRAK

Biji benih progeni dialel separa 6 × 6 telah digunakan untuk menilai kesan genotip (induk dan hibridnya) terhadap ciri percambahan Jatropha curcas di Universiti Kebangsaan Malaysia. Ciri percambahan didapati berbeza secara bererti (p<0.1) pada biji benih hibrid dan induknya. Percambahan dimulakan pada hari ke empat selepas penyemaian dan dibiarkan sehingga 15 hari. Percambahan biji benih adalah berbeza-beza dari 58.06 hingga 92.76% antara induk dan dari 53.4 hingga 98.96% antara hibrid. Percambahan tertinggi dicerap pada hibrid P2 × P4 dan tiada percambahan 100% ditunjukkan oleh hibrid dan induk. Indeks percambahan GI dan indeks kecergasan anak benih SVI didapati paling tinggi masing-masing pada P1 × P5 dan P1 × P2 dan paling rendah pada P2 × P4 and P3 × P6. Kebanyakan parameter percambahan pada induk menunjukkan nilai yang kurang baik berbanding hibridnya.

 

Kata kunci: Bahan api biologi; dialel; hibrid; indeks percambahan; kecergasan anak benih
