Vegetable Soybean Cultivars belonging to MG III thru V were evaluated for their Seed Yield Efficiency (SYE) and Resistance to Heliothis Zea.

This study was conducted in 1968 and 1969. Each entry was planted in a single row plot. Each plot was 5.0 m long and 0.75 m apart in a randomized complete block design with 4 replications.. All entries were evaluated for Seed Yield Efficiency by computing the ratio of seed dry matter wt. to non-seed dry matter wt. and their resistance as the percentage of damage pods.

Preliminary data indicated that cultivars kim and Oakland (MG III), Kingston and Jefferson (MG IV), Pershing and PI 416.467 (MG V) were very high in SYE while Fuji (MG III), Sanga (MG IV) and PI 417.266 (MG V) were observed to have high level of resistance to Heliothis Zea.

We hope that these cultivars could be used as parents for the development of Breeding Program in Vegetable Soybean.
