exploit yield heterosis through hybrid rice technology. Several traits contribute to hybrid rice seed
production efficiency, and
thereby enhancing hybrid seed set. Few rice stigma exsertion types are enumerated but phenotyping
methods are not systematic and well compared. This study reports the extent of variability for the trait
in par
some of them, and identifies good donors, namely BF16B and BF96B for the trait. During
phenotyping, sample processing was improved for non
storability between sampling and phenotyping. Method comparison analyses between the two
modified phenotyping methods for stigma exsertion indicate that the whole panicle and the panicle
zone methods are statistically on par in quan
interchangeable. However, the latter being less resource demanding, may be the choice for stigma
exsertion phenotyping in rice.DB
