Effect of plant types on grain yield and lodging resistance in pea (Pisum sativum L.)

Published on

In the present experiment 56 diverse pea genotypes were
chosen belonging to seven different plant type groups and
observations were made on eight traits related to yield and
lodging. Normal foliage with reduced stipule plant type
(stst genotype) found to be shortest (in terms of days to
flowering and days to maturity) while, semi-leafless plant
type had the highest 100-seed weight as compared to the
normal plant types (LeLe AfAf TlTl StSt). On the other hand,
the pleiofila with reduced stipule foliage type (afaf tltl stst)
had smallest 100-seed whereas, seed yield per plant was
highest in case of semi-leaf plant types in both tall and
dwarf groups. Similarly, Pleiofila with normal and reduced
stipule plant types in both tall and dwarf groups were found
to be more lodging susceptible than the normal.The dwarf/
semi-dwarf genotypes combined with semi-leafless peas
appear to be the most ideal plant type that would provide
better tolerance to lodging and yields high.
