Morphological characterization of four peanut (Arachis hypogaea L.) varieties under Lal-lo, Cagayan condition: Its phenotypic changes to type II climate of the Philippines
Abstract
The study was conducted to characterize the four peanut varieties during wet season with type II climatic condition in terms of its morphological characteristics. The treatments used were: T1 – Luna Seeded, T2 – BPIPn9, T3 – NSICPn11, T4 – NSICPn17. These were randomly allocated in the different plots following the Randomized Complete Block Design (RCBD). The results of the study are: (1) erect growth habit, stem pigmentation, glabrous type of hairiness, alternate types of branching pattern, opposite leaf arrangement, yellow-orange flower color in all varieties were noticed; (2) leaflet shape: luna Seeded and NSIC11 exhibited elliptic while BPI Pn9 and NSIC17 exhibited lanceolate; (3) leaf color: luna Seeded and NSIC17 exhibited a dark-green while BPI Pn 9 and NSIC 11 exhibited light-green (3) pod Beak.: Luna Seeded and BPI Pn 9 exhibited prominent types, however, NSIC 11 and NSIC 17 has slight type; (3) pod constriction: Luna Seeded, BPI Pn 9 and NSIC 17 exhibited prominent types, while NSIC 11 has a moderate type (4) pod reticulation: Luna Seeded, BPI Pn 9 and NSIC 11 gave prominent types, however, NSIC 17 has a slight type; and (5) primary seed color: pink were predominantly noticed in Luna Seeded, BPI Pn9 and NSIC17, while NSIC11 has a tan seed color. The four peanut varieties are suitable under type II climatic condition. However, it is important that genetic purity and viability of the germplasm is maintained as a separate activity of agricultural R & D agencies.
