POLA PEWARISAN GENERASI F2 TANAMAN JAGUNG (Zea mays L.) VARIETAS LOKAL HASIL PERSILANGAN RESIPROK
Abstract
Maize (Zea mays L) is one of the important food ingredients that has great
potential and is a leading commodity. Pulut and purple corn have their own
advantages in the content of amylopectin and anthocyanin. Seeing the advantages
of the two varieties, there is the potential for further development which is to
assemble hybrid varieties by crossing them. The crossing method used is the
reciprocal method. Then the observations were analyzed using the chi-square test
for qualitative characters. While the heritability was calculated to test the
quantitative characters and the selection index was also calculated. Inheritance of
phenotypic characters of F2 generation seeds resulting from crossbreeding of
purple and white corn (Zea mays L.) reciprocal plants does not show a pattern of
segregation. The heritability value of F2 generation is high in Pulut x Purple
crossing based on grain length, grain thickness and anthocyanin characters. While
the value of heritability of generation F2 is relatively high in Purple x Pulut
crosses based on grain thickness, amylopectin and anthocyanin characters. Pulut
x Ungu corn selection results from reciprocal crossing have a selection index
range of 1.40-2.67. While the Purple x Pulut corn from reciprocating crosses
has a range selection index of 0.85-1.19.
