A study on stigma receptivity of cytoplasmic-nuclear male-sterile lines of pigeonpea, Cajanus cajan (L.) Millsp.
Stigma receptivity in pigeonpea [Cajanus cajan (L.) Millsp.] was studied using 2 male-sterile lines (ICPA 2039 and ICPA 2043) under field conditions. An experiment was conducted to observe the stigma receptive period at Nanning (22°N 108°E) in Southern China. The study revealed that the stigma was receptive 48 h before flower opening and continued up 4 days after flower opening. The peak stigma...

Phenotypic variation of cacao (Theobroma cacao L.) on farms and in the gene bank in Cameroon
A survey was undertaken in the 2 major cocoa producing areas (Southern and Western) of Cameroon to study the morphological diversity existing in cacao farms in relation to genetic diversity in gene bank accessions. A total of 300 farm accessions (FA) were selected in the field which were compared to 77 gene bank accessions distributed into 4 groups (AGs) according to their origin. The 17 quantitative and...
