Testcross performance for anthocyanin and antioxidant activity in the ear components of purple waxy corn lines

Kalapakdee W, Dermail A, Lertrat K, Sanitchon J, S Chankaewi, Lomthaisong K, Surihari B

Published: June 2020

The anthocyanin and phenolic yields and antioxidant activity of seven waxy corn genotypes, their F1 progenies, and hybrid checks grown during two growing seasons in 2018–2019 were assessed. The mode of gene action on the traits of interest was investigated, and promising lines with high anthocyanin in whole-ear components were identified. An overwhelming dominance genetic effect, high reciprocal cross effects, and low heritability for targeted traits in corn husks and cobs were revealed. Promising lines, namely NSX/DKA/PF for corn husk anthocyanin content, PF/AB and S6248/TB/KND//PF for corn cob anthocyanin content, and PF/AB and TB/KND//PF for corn kernel anthocyanin content, were identified.

Published: June 2020

The diversity and functions of bamboo in peatlands were determined. Five genera, 17 species, and three varieties were identified and delineated into two groups. The most closely related species were Bambusa vulgaris Schard. Ex Wendl. var. striata and B. vulgaris Schard. Ex Wendl. var. vulgaris, whereas the most distantly related species were Gigantochloa kuring Widjaja and Gigantochloa atter (Kurz). Bamboo had 21 types of uses and is generally used as a soil-retaining plant and a clean-water filter. B. vulgaris Schard. Ex Wendl. var. vulgaris had multiple purposes and showed adaptability to all types of habitats. This species has the potential to be developed in peatland areas.

Starch accumulation of cassava genotypes grown in paddy fields during off-season

Nimlamai T, Banterng P, Jogloy S, Vorasoot N

Published: June 2020

Starch production by four different cassava genotypes grown in four different upper paddy fields during the off-season of rice was studied. Early storage root formation, rapid starch production rate, and high starch yield accumulation were identified as relevant traits top-yielding cassava genotypes in off-season rice paddy systems. CMR38-125-77 was identified as a satisfactory cassava genetic resource.

Identification of the secondary metabolite capsiate in Capsicum germplasm accessions.

Tarinta T, Chanthai S, Lertrat K, Nawata E, Techawongstien S

Nineteen pepper accessions were evaluated for high capsiate levels without capsaicin. The presence of capsiate and capsaicin were evaluated by using two DNA markers. The KKU-P31146 accession showed the highest capsiate levels without capsaicin and could be used as a new source for breeding high-CAT accessions.
